One of three types of battery can be selected for the electric screwdriver:
The first type models are large. They are notable for their low cost and smooth operation at negative and positive temperatures. These devices can be charged a large number of times, but due to the memory effect, they must be stored fully discharged. Charge also after the battery has reached the end of its useful life.
The memory effect is referred to as a decrease in battery capacity, which reduces the duration of use of the device between charging procedures. The indicator of remaining charge is fixed by the battery, and after recharging it will consume energy to this level. Therefore, it is important to fully discharge the battery capacity when working with the tool.
Batteries of the NiMH group are lightweight and environmentally friendly. They can work for long periods without additional recharging. Models of this type are also equipped with a memory effect, but it does not affect the battery performance as much. A considerable disadvantage of this line of batteries is intolerance to negative temperatures. When the reading on the thermometer drops to minus two degrees, the battery gradually loses its charge. Store tools with this type of power in a warm room, discharging the battery completely.
Batteries of lithium-ion type appeared in 1991 and became the most popular and convenient power source. They have no memory effect and have high capacity and can hold a charge for a long time. Almost half the weight of comparable batteries. Can be recharged at any battery capacity. Screwdriver models for professional use are most often equipped with this type of battery.
Cordless angle grinder (angle grinder) 800W 18V (Makita battery)
A small review (comparison) of a cordless angle grinder (angle grinder). The beauty of wireless compact grinders. you can cut or clean up without any fuss. And no need to unwind extension cord, and no need to balance at height with large corded angle grinder. zzzhzhik. and that’s it. And in this case, even a great price (37).
As a matter of fact, I’ve already mentioned this angle grinder (reference to the action at 36). We will talk about a specific model of angle grinder, which runs on a battery type Makita 18V.
Features: Type: Cordless Brushless Angle Grinder Features: Adapted to 18V Makita battery Power:18V Power:800W RPM Speed:10,000 rpm Spindle diameter:14mm Disc diameter:100mm
A little distraction, tools. The Chinese, of course, well done. Released a series of tools that do not copy, but complement the well-known brands. You can find cordless tool carcasses like Makita, Bosch, DeWALT and more. Keep the old batteries, and you can order any tool you want. A concrete example: I bought on sale Makita electric screwdriver set two batteries the case charger. electric screwdriver is not enough for me, I bought a wrench to him. There was a review on the wrench, great tool, 1/2″ seat, brushless motor, 100nm does! At the link to the wrench in the lot is the charger and batteries (non-original) In general, such a way you can buy a lot of tools under one (!) battery: cordless jigsaws, circular and saber saws, blowers and peorators, impact drills and more.
So, as for the angle grinder itself. the usual cordless (cordless) compact angle grinder.
The length is convenient, only 320 mm. Easy. With the battery at 5.0 Ah is heavier, but not the point.
Included was a cover, nuts, washers, wrench. The battery is already looking for separately.
The battery is a standard Makita type DGA504Z 18V. Note, the soleplate has an indicator, and two modes of operation (more RPM. less RPM). At low speeds it is convenient to work with the brushes. With the battery looks a bit bulky, but the balance is more or less respected. The power button, or rather the slider, is standard. This point is implemented in the same way as others, there is no discomfort at work. Metal gearbox, marking of rotation direction, shaft blocking. The spindle is small, M10, for small disks.
Yes, it came with a wrench. For comparison. the angle grinder from Wosai. They are twin brothers, run on the same type of battery, can be switched from Makita to Wosai.
About this angle grinder I also did a review
And also an angle grinder Worx
All have the same design, more or less similar dimensions. For comparison, the hoods of the Wosai, Worx angle grinders. I bought a separate cover under the worx for 125mm. The original one from the angle grinder goes to 115. Examples of references: cheap, a lot to choose from. Diameter seating 42. 44 mm.
Now about the seat for the disk. Originally designed for 100/16mm disc, spindle thin. Basically it fits 115/16mm max. It looks like this with real nuts Under the big disk you need to install spacer rings or “modernized” nuts and washer for 125/22mm. The disk fits well on these “upgraded”, with an enlarged casing works, there is no runout. I do not recommend working without a hood.
Yes, the kit also included a handle
This is what it looks like with the handle I use it seldom, because it becomes inconvenient and more bulky. The handle can be moved to the other side.
Just in case, let’s check the reducer. It has a sealed bearing, the grease is present.
So the angle grinder is packed and ready to go. In the background is the home band saw Grinder))))
What can I say about the work (I tried a strip 4mm, angle, pipe, etcп.). Saws more or less. Suitable for short-term work on thin-walled metal. The rods and small items no problem sawing. But under a heavy load, it withers. imho, it’s the fault of the cheap battery. It just does not give the necessary current and goes to the cutoff (battery from an electric screwdriver). If you have an original Makita 18-volt battery, especially the 5-volt model.0 Ah (high-current), this angle grinder is your choice. For the ridiculous money you get a useful tool. But if you need to buy another charger and batteries, I would think twice The angle grinder, on the other hand, handles small tasks (e.g., sawing off a rod, a small corner, scrape off rust). If you compare a small angle grinder with a large one, then, of course, it loses in power, and will not replace a full-size network angle grinder. But it’s a great addition to it.
To take or not to take. you decide. Quality meets cost. Of the more expensive ones, I can recommend something like Milwaukee 2780-20 or DeWALT DCG412. A bit more expensive, but a bit more powerful.
Thank you for listening!

Battery for Makita power tools
“Makita” batteries for power tools have become in fact the standard for Chinese manufacturers. My brother and I have a few tools to this standard (unfortunately, the original Makita tool is not available), and since the battery is not a lot. I asked for this battery review. Acting on the principle of “die so with the music”, I took the highest-capacity battery at 6Ah, not really counting on a fair capacity and did not go wrong.
There is no readable inscription on any of the chips. No protection, no balancer either, in my opinion, not for sure though. Or rather, it seems to be a repetition of Makita’s know-how, where the control goes to the minus bank, that is, we can say that there is no.
Only on one battery I saw the marking:
I ran the test again and squeezed another 200mAh, that is, the capacity here instead of 6Ah is only 4.5Ah, which I basically expected. In principle it is possible to discharge to a lower voltage, but 1.5Ah is not enough there anyway.
On operation. It seems this battery has more current capability than the one in the nutrunner, at least the chain saw makes more life and cuts better with this battery. All in all, from my point of view, it is not the worst. Unfortunately, I have no way to check the compatibility with the original Makita tool. When using with Chinese tools, especially with the collector motors, you need to monitor the battery level in order not to discharge it too much, because there is no protection, I repeat, no. In the tool with a commutatorless motors has a controller, which is likely to over-discharge the tool will turn off.
At the time of ordering, as you understand, there were no problems with delivery to Belarus, now alas. “no shipping method available”. and it’s a pity.
And we have the usual discount coupon BG927125 valid until March 31

Makita 18v cordless screwdriver
Color: Blue Black No-load RPM: 0. 2700 Blocks per minute: 0. 2700 Max. force: 520200Nm (note by author) Chuck: Quick-action 6mm Power: 18V Makita battery Weight without battery: 1kg (note by author)
Unpacking and Appearance
Cardboard box Nothing superfluous, no podiums, only package, only hardcore In the kit only “body” screwdriver, the controls are classic At the base placed an indicator of the remaining charge, speed and button to adjust it As I wrote above, from the screwdriver differs only chuck, this quick-release for 6mm bits By the way, the white rim of a transparent cap is lit in the dark Powered by “Makita” 18V batteries. “Analogue with the wrench is perfect, no backlash You can buy a few pieces at once, typing into the search engine “MAK-18B-Li”, the choice is quite large The charger I have this, works without problems, at the end of a brief note about it.
The indicator on the left shows the battery level, three speeds, the fourth cell is reverse
Button is multi-step. On the first speed you can crank from 500 to 1800 rpm
On the third to 2500 rpm, reverse the same
To compare the two types of tools bought for 3 years adapter from a square to a 6mm chuck Looks good, it comes with a pin to fix it and a rubber band to compare it with this model, t.к. It is the most powerful one I have. Before After Insert the pin Fix the rubber band, you can use For the test I bought these gizmos. Do not know the correct name, but huge And the corresponding nozzle Fixed securely I will screw in without reaming in the stump (saw cut is relatively fresh), started at maximum speed
Let’s go to the impact wrench with the adapter. At first speed, the screw screw screwed in about 70 percent
The second is better, but here is the speed is clearly inferior to the sub, although at idle speed it has more
The result in the photo. The only thing I could unscrew was the one that wasn’t completely tightened.к. by hand I also did not overpower them and if you look closely, in the background in the gifs you can see a piece without a cap. I was wondering what size tool can not handle, so I bought the longest one “screw”, probably 20 centimeters drove it black until it gave up, then literally a couple of turns pulled the screwdriver and that’s it. It didn’t move to the left or right anymore, by the way, I think I invented another way to get fire
Took it harder, pushed it and broke the consumable in half. All in all, some pretty nasty stuff
I didn’t compare it to an electric screwdriver, t.к. burned one, comparing with the very first wrench. The beauty of the pulse models is that when you lock the output shaft, the motor continues to rotate, you get a kind of load limitation with a periodic shock to the side of rotation (not to be confused with the percussion tool, which work as a peorator)
I do not understand why plastic cover is needed, to preserve the aesthetic appearance? hollowed out the body board at the base poured compound motor brushless, did not cheat Button Shock mechanism is metal, disassembled after testing, no signs of wear No grease spared Gear is full metal, by the way, earlier I did not think to disassemble it Well, to the gear shaft of the motor as well claims no
As usual made the exclusive coupon BG3OMG, which lowers the price to 37.99 including shipping. As far as I know, in Ukraine and Belarus will be even cheaper)
There is also a coupon BGMKT2, he lowers the price of the charger to 25.99 including shipping
I will not post a separate review, who is interested, details are in the spoiler
In the kit was the device itself and waste paper There are no buttons, only a screen and two indicators at the bottom, in the center of the deciphering, there is a sound alert Behind a nameplate with the characteristics of the battery is fixed as a tool, the charger beeps, the red indicator lights up and the screen begins to display the current voltage and progress in percentage
Most likely 3A really gives out, t.к. The process goes pretty quickly. At 95% apparently gives the battery a little come to itself, then brings it to full, the green light turns on and sounds a short and not very loud melody
Internals I do not know what pins of the balancing connector had to “probe”, but on the plus and minus voltage slips on some pins. On the other hand, there’s no balancing in battery copies anyway, so it’s not that important.
Interesting model for scale work. It doesn’t leave small screws a chance to survive, but it twists big ones without any effort. When watching “Legends Destroyers” I noticed that they fix all wooden structures with similar screwdrivers instead of screwdrivers, which are the universal cordless tools in our country. Not a bad chuck, during the test the bit has never been jammed and it easily fell out when the ratchet moved The brushless motor no longer surprises many, but it is nice that they began to apply in the budget models To power it are used fairly common Makita batteries and their inexpensive analogues
I don’t even know what can be classified as a minus, except that the discrepancy is the torque, because 520Nm was promised, but it should be understood that it is a lot for the stated price and the models for the same 400-500Nm are much more expensive. It’s like buying a 64 gig flash drive for 300-500 at Ali store in 2014 and hoping that the capacity is real (personal example). True, it is not so bad and the actual torque is about 200Nm. The black one from the previous review was about 170, this one is a bit more powerful.

Which batteries are suitable for a Makita electric screwdriver
In addition to the type of power source, other characteristics are also important. So, the battery voltage directly affects the performance. Household instruments for which intensive use is not expected, the battery voltage to 12 V (screwdrivers, wrenches) or up to 24 V (drills, jigsaws, grinders, glue guns) is enough. Professional tools require a battery with up to 36V.
Another important characteristic of the battery is the capacity. All other things being equal (operating voltage, intensity of use), a power source with a larger capacity will last longer. At the same time, the cost of the battery also depends on the capacity. Therefore, if the tool is not intended to be used intensively all the time, you can look at power sources with a smaller capacity and therefore a lower price. For professional use, it is worth buying a higher-capacity model, and if the operation will be quite intensive. it is best to buy two batteries at once, in order to avoid forced interruptions in work.
The choice of charger for Makita batteries has a major influence on the charging time. The fastest way to charge a battery is to use a fast charger (for example, the Makita DC1439). This result is due to the internal air circulation system: it prevents the battery from heating up too much and makes it possible to charge at a higher voltage. There is no danger of the battery failing.
There are also Makita car battery chargers. They are extremely useful in the field when no mains power supply is available in the immediate vicinity. That makes Makita power tools even more portable.
But the most important criterion when choosing a charger is the type of battery. Some battery chargers can work with virtually any Makita battery (for example, the DC18RA), but others are only good for charging nickel-metal hydride and nickel-cadmium power sources.
Many for household chores. furniture assembly, bolt ties, etc.д prefer to use cordless screwdrivers. There’s a good reason for this. it’s quick, there’s no electricity, it’s convenient. Yes, it is more expensive than a screwdriver, but it is much better in terms of comfort of use.
There are certain nuances of working with such equipment fast battery discharge, slow charging, lack of voltage. And this is not the whole list of problems that may be faced by the owner of a cordless drill. To avoid such situations, it is recommended to choose the right battery for an electric screwdriver, while taking into account all the specifics and operating time of the machine.
Chinese Li-Ion battery 18 V, 4.0 Ah replacement Makita BL1815/B, BL1830/B, BL1840/B, BL1850/B, BL1860/B
Before reviewing I will describe quite an interesting situation that occurred to me when buying this battery. I ordered it from Russia, so it was received within 4 days by an IML courier, and the delivery was completely tracked.
After opening the box, first thing I pressed the test button and nothing happened. Т.к. I was not at home at the time and there was no way to check something, I assumed that just a faulty light. But it turned out to be a little more complicated than that.
What is Prostormer and why they have different battery voltages
Prostormer. Chinese brand on aliexpress. They make pretty good quality tools. By the way, if you want to buy something, read my advice on how to buy cheaper.
Prostormer has two lines of batteries. One is similar to the Dewolt 18v batteries. The Chinese call them 20v max lithium.
Others are similar to Makita 18v. They are called 21v max lithium.
There are 5 or 10 (depending on the capacity) 18650 cells inside both batteries. Each cell, depending on its degree of charge, has a voltage ranging from 2.4V to 4.35В. The conditional rating is 3.7v, but that’s just the marking. Brands write “18v” on these batteries ( 5 3.7 = 18.5 ).
The Chinese marketing people seem to think that if you write more they are cooler. over, it is impossible to find fault. on such batteries, if fully charged, the voltage will be even higher than 21v ( 5 4.35 = 21.75 ).
This also applies to brand-name 18v batteries. Do not listen to official Makita dealers, saying that there is some kind of protection in the tool and the “21v” battery should not be used in Makita tools at all. All batteries have the same cells inside and the electronics only balance the charge among the cells, but do not limit the output voltage of the battery as a whole.
Makita sometimes sells tools without batteries at very competitive prices.
But a set of one battery charger will cost you as much as two Prostormer 21v electric screwdrivers along with a battery and charger each.
If you already have a Prostormer 21v max lithium line of tools. then you don’t need to buy anything else at all.
If you insert a Prostormer 21v max lithium battery into a Makita tool, it just won’t start.
And that’s where the “wise” Makita salespeople come in from over their shoulder and start telling tales of what super batteries and super protections Makita has.
But the real reason is that the Chinese don’t put a thermistor in their batteries to protect the battery from overheating.
Реальный тест аккумуляторов Макита с Алиэкспресс
The resistor is connected to the plus side of the battery and is connected to the center contact (the one closest to the plus side). The Makita tool measures its resistance, and if it’s too high, which signals that the battery is overheating, turn the tool off.
My experience with the Prostormer shows that batteries don’t overheat to any noticeable degree, so the lack of temperature control doesn’t affect anything.
That’s why I didn’t try to match the thermistor, I just put a plug instead. 20K ohm resistor. If you don’t have one handy, you can quite safely just wire the middle contact of the thermistor to the plus contact (the one closest to it).
There is only one problem. the Chinese, although they did not use in any way the middle contact of the battery, “optimized” the wiring of the circuit board and put one line through it.
So before you connect the center and side pins, you need to rewire the tracks connected to the center pin. There are two of them, on the bottom and on the top of the board. And replace the broken this connection with a wire.
You can see how I did it in the photo. In the white shrink tube. My resistor, which, like I said, you can just replace with a wire.
When reassembling don’t forget to put the button spring back in place.
After this redesign the battery will work in Makita tools. Charge normally with their regular charger. And will continue, of course, to work in Prostormer tools, because they do not have this central contact at all.
Denoted by the symbol NiMH. Have higher specific capacities, up to 75 Wh/kg, so they have a higher ampere-hour rating at the same size as the NiCd. Another advantage is that there is almost no memory effect. However, they hold a worse charge in cold weather, so it is not recommended to leave the tool in unheated garages or in the trunk of the car. A Makita battery of this type will not last more than five hundred charge-discharge cycles.
Black battery compartment. The form factor is the same as that of NiCd cadmium batteries up to the same size. So if you want to turn your amateur electric screwdriver into a semi-professional one, just replace the battery with a metalhydride battery with the same voltage rating. Capacity and voltage ratings are given in the table.
Increased battery capacity increases the status of the tool, making it a semi-professional tool that can work for a long time without recharging. It is worth noting that for almost the same torque, a 14.4 volt electric screwdriver is preferable because it consumes the battery more economically.
Makita 18 volt cordless electric screwdriver/drill
I will probably start with why I ordered. The reel was supposed to be brushless, compatible with Makita batteries and metal 13mm chuck, which indirectly hinted at the presence of spindle lock.
As it turned out, not everything that I am interested in is available. Now the product description was changed and also the version with 13mm chuck was stopped for sale. But I will not get carried away, I will pass to the review, where I will try to tell about everything in details, and also about what difficulties can expect users of similar tool.
The packaging is very simple, a cardboard box and a plastic bag.
Inside the package is an electric screwdriver, nothing else, not even a manual.
The design of the housing and the general appearance really reminds of a tool of a famous company both in color and in shape.
The nearest similar in my opinion is Makita DHP 482 Z, but if you look carefully, you will find some differences, but at a cursory glance they are invisible.
Weighs just over a kilogram without battery, which is about 300 grams less than my Milwaukee 2607-22CT M18, the full weight will depend on battery capacity, respectively. Since my Miluki is roughly in the same “weight class” and has the same functionality, I will periodically compare the reviewed unit with it during the review.
There is no name tags on the housing, not just labels with the specifications, OEM as it is.
The handle as well as other parts of the body is rubberized, the inserts are relatively rigid, the grip is just fine, but here thanks to Makita engineers. 2. The power button is standard for similar devices, on top of the switch is classically located the direction of rotation. There is a LED backlight, but unlike both Makita and Milwaukee it just sticks out in a small hole and has no diffuser. The backlight shines, as usual, “somewhere”, but not where it should. 3. The engine and gearbox compartments are also protected by rubber inserts. 4. I paid attention already on inspection that the motor is obviously a regular one, and when I was preparing a photo, I noticed that even the marking is visible through the housing holes.
On top of the gear shifter, protected front and back by housing overhangs.
Of the available specs information, there was only a label that was clearly taken “from the ceiling”. As an example, the maximum torque is listed at 350Nm and up to 4000 RPM, but for example Milwaukee only declares 50Nm and up to 1800 RPM. I didn’t measure rotation speed, but subjectively Milwaukee has about 20-30% higher rpm, I think I would definitely notice the difference between 1800 and 4000.
an electric screwdriver, or rather, a cordless drill, has three modes of operation, the actual electric screwdriver, drilling and drilling with impact. There is no torque limit in drill mode. Above is the torque limiter adjuster, the markings have 25 steps, in reality there are 18, so it hits as it has to. Milwaukee has 18 steps as well, but the gears are also 18 and no such problem. 2. The chuck has a metal body, marked simply 1/2″ 13mm. 3, 4. No complaints about the cartridge, the minimum diameter is not listed on it, but 1.5mm clamps fine and you can hardly use a smaller diameter.
It would be possible to say everything is fine, the chuck clamps with characteristic “click”, but there is a “nuance”, the electric screwdriver has no spindle lock, so it is not convenient to use such chuck in the torque limitation mode, because you have to switch to a bigger torque often to unclamp. As an example, to fix enough to put the regulator to 5-7, but to unclamp, it is already about 21.
On the bottom of the battery pad, there is some strange marking, either 142, or 14L, or even 14V. But the key here is that there are only 2 pins to connect the battery. You will of course ask how much you need? And here is the second “nuance”, you need 3 contacts.
The thing is that compatible batteries don’t have inside elements which can switch power circuit, that’s why the regulator of the tool which is controlled by the battery controller through the third contact. Not only Makita battery has such a feature, the Milwaukee M18 has the same. The third contact is also present in Chinese boards, in the photo you can see a powerful transistor, it is in the charge circuit and has nothing to do with the load.
In the photo of the disassembled brand tool is clearly visible third wire, as the third contact was in a cordless angle grinder, a review of which I did about a year ago.
This is fraught with the fact that in the case of overdischarge, or worse, unbalance, the battery can be damaged.
And what’s interesting, I found pics of Makita with a 14 volt battery, there are only two wires, I assume that the protection is located inside the battery.
Disassembly. To open the housing will need a screwdriver for Torx, I approached the bit T-10, but since some screws are sunk deep, I used a screwdriver from the kit from the camera Hikvision.
The halves of the body fit together very tightly and if I didn’t know I was taking apart an anonymous Chinese tool I would have thought it was a “company”.
Inside you can also see that the connection diagram is two wire. 2. Regulator 7.2-24 volt, 16 amp, stepless adjustable up to about 70%, then the power circuit just closes by individual contacts and you get 100% RPM. 3, 4. It is pretty simple inside, but one of the wires is crushed by the edge of the case.
The motor with the gearbox and the gear shifter.
The motor is disconnected very simply by turning relative to the reducer and the output from the catches.
You can say it’s a standard motor for this kind of tool, RS550 for 21 volts. 2. Inside we found some rubber remnants from the filler that covered some of the vents. I took them out without much trouble, but then I thought, maybe I shouldn’t have, they additionally pressed the engine and didn’t spoil the appearance.
Gearbox case is plastic, insides are metal. Did not pick it up, but I can say that in my opinion it is ok, the only thing I would not load it too much in the percussion mode.
Unfortunately, due to health problems I was not able to make a proper test, partly because of these problems the electric screwdriver was at my disposal since the middle of February, and only now I could make a review.
I checked it nevertheless in work and can quite make some conclusions.
All tests used a board with a thickness of 50mm, here is an example of drilling with a “feather” of 25mm.
The 35mm Forstner drill bit, both here and in the previous example, didn’t notice any difference with the same Milwaukee.
I tightened the screw 6×70 with a whistle, even without pre-drilling, but as it turned out the ratchet was disabled.
After that, I tried screwing in the 8×70 screw, also without drilling, but it didn’t work completely. When I took the picture, I realized that somehow I wanted too much, because I screwed at the second speed, of course the screwdriver didn’t like it.
As a result, after the screw 8×70 there was some unpleasant smell and even a little smoke. The body of the electric screwdriver is also heated, thermo picture taken after about 4-5 minutes, I didn’t realize it right away, and then I didn’t want to force it again.
Okay, I switched to the first speed and tried again. The 6×70 goes in a little slower, but sinks together with the flat, but it feels that the load on the engine is clearly less.
In general, here we can say that it is normal. Truth it turned out, that it drives completely only with ratchet turned off, that’s two last adjusting positions (though usually either only the last one, or in drill mode). If the limiter is on and set to maximum, the 6×70 goes in almost all the way to the thickening after the thread, and the 8×70 is about 1/2-2/3.
And a little visual comparison with the Milwaukee. Dimensions are about the same, but there is a slight difference in the shape of the handle, the reviewed battery is slightly shifted forward.
Length and height are also almost identical.
Conclusions. As always I will start with the good stuff. Drills, screws, screws, pulls pretty good. No complaints about runout or backlash, about the same as Milwaukee. Sits well in the hand, the weighting is the same as in Milwaukee, but it’s a little heavier. Also, I would not particularly scold and build quality, can probably only complain about the jammed wire, otherwise fine.
Not without its flaws. In my opinion the biggest three, and one of them is a consequence of the other: 1. The chuck, it’s good, with a secure hold, but the fact that it takes one force to lock and another to unlock, really strains. If you work with one tool it is ok, but if you have to change it often and you use the torque limiter it is a nightmare You have to constantly go from low to high to work to high to release the chuck. 2. No spindle lock, if there was one, there would not be the first disadvantage. 3. The lack of a third battery contact and, accordingly, the lack of protection against battery overdischarge, unfortunately, clones are often seen this.
I know it’s not a commutator at all, it’s a regular motor, alas If you compare it to Milwaukee in terms of torque, the reviewed one is a bit weaker, but I wouldn’t say there’s much of a difference.
The store offered a discount on a version with a 10mm double clutch chuck, which just works fine without the spindle lock. With the code BGdd017c the price will be 27.19, through June 30
Also offered a discount on another model, which is claimed to have a commutatorless motor, and looks better, with the code BGb8fa5b will cost 39.19, until June 30.
