Concrete cutter head: Features of the tool
In some ways, a concrete cutter for a peorator is hardly called a circular saw, because there is very little in common between them. except for the tubular construction with a drill bit in the center. Instead of standard saw teeth, this tooth bit is equipped with tungsten carbide inserts, which are able to withstand both the friction and the impact caused by the torque. We don’t want to talk about sets, because you have to buy different tools for different hole diameters.
Hammer bit for drilling holes in concrete, despite its power and ability to crush concrete walls, can not withstand reinforcement. When it hits the armature, which happens almost every time during drilling, the cutting tips fly off, and generally speaking, the expensive tool is hopelessly ruined. I do not want to say that it is a useless tool, it is just necessary to understand that while working, getting on armature, the core bit should be removed and instead of it the usual pick should be set on the motor to finish the job. Subsequently, the rebar can either be bent with a hammer or cut with an angle grinder.
We describe everything about circular saws in great detail
Some people call a circular wood saw a end mill with good reason. the material processing is practically the same, and the tools look similar as well. The considered tooling, although it leaves a lot of shavings, but allows, using an ordinary power tool, to obtain clean through holes in wood.
Sorts of bits
At the same time, there are quite a lot of different types and purposes of drills, which help to achieve the desired result. Define several types of nozzles that are used for woodworking, among them:
There are many different kinds of bits for working with wood.
Each type is used in separate works, and also has a different structure, which allows you to apply drills for their intended purpose. When choosing a wood drill for a home tool set, it is worth looking for the greatest selection, but also to match the price. It is necessary to be guided by quality indicators and characteristics.
Circular saw: varieties and possibilities of the tool
To cut a round hole in any material has never been a problem, especially today, when craftsmen have at their disposal such device as a circular saw. In almost all cases, it is a nozzle for a drill or peorator, which allows you to cope with almost any type of material. It is this tool that we will get acquainted with in this article. together with the site stroisovety.We will study the variety of tools of this type, understand its purpose and features, and take a little excursion into its practical application.
Cement mortar peorator crown: the specifics of the tool
In a way, it is hard to call a cement mortar crown for peorator a circular saw, because there is very little in common between them. except for the tubular construction with a drill in the very center. Instead of the typical saw’s cutting teeth, such a crown is equipped with hard-alloyed pobedite tips, which are able to withstand both the friction and the impact created by the peorator. In this case we can not speak about kits, since a separate tool should be bought for different hole diameters.

The crown for drilling concrete holes, notwithstanding its own power and ability to divide concrete walls, is not able to resist rebar. When it penetrates the reinforcement, which is almost always the case during drilling, the fillings fly off and, on the impressive count, the expensive tool becomes irreparably damaged. It is not necessary to state that this tool is meaningless, it is just necessary to keep in mind that during the work, when you hit the armature, the crown should be removed and replaced by the ordinary saw, which can be used to finish the began work. Then the rebar can either be bent with a hammer or cut with an angle grinder.
What is better a wood crown or a ballerina?
There is an ongoing debate in furniture design communities over which tool to choose. the crown mill or the ballerina tool. This wood crown drill cuts a hole thanks to the two sharpened plates. By adjusting the distance between them, it is possible to get the notch in any size. The main difference between the tools is that the core bits have a fixed size, and you can drill a hole of any diameter with the ballerina. There’s no definite answer as to which is better, it all depends on the type of work involved. When carving wood, the best one will be a ballerina, and it is easier to drill holes in ceramics with a sprayed crown.
Review: Stayer Wood Circular Circular Saw Set. A great set, almost no notes.
Everyone who works in wood should be familiar with these so-called circular saws.This is the set of Stayer wood circular saws that we will talk about next. For concrete, there are also analogs, but that’s another story.
HOW TO USE A CIRCULAR SAW FOR BEGINNERS- PART 1
Stayer is a well-proven brand, so I got it without thinking too much. Time and practice have shown that for good reason.
The set includes 12 different diameters: 19,22,28,32,38,38,44,51,64,76,88,102 and 127 millimeters. These are the most common sizes, for example, if you are working with PVC pipe.
Each ring saw has a cutting depth of 22 millimeters. If you have to work on thick wood, you have to do some jiggering to get the wood out of the steel bit warmed by friction.
As you can see from the picture below the drill bit is suitable for drilling holes in solid wood, plastic, chipboard, OSB, drywall and plywood.
The saws are stored in a handy gray plastic case:
Digits are inserted into each other to save space. There are two special saw clamps.
Each bit is marked with diameter in inches and millimeters on the back.
This is how a drill bit and core bit look assembled (top view):
There used to be an extra fixing plate, but the teeth broke off pretty fast. Without it, the bit can be assembled all right.
I need this set for making holes for lights. Myself make on a summer cottage lighting and ceiling chandeliers.
I am very satisfied with the purchase. Chalky flaws are compensated by versatility, versatility and longevity. In four years the teeth haven’t broken off and the saws haven’t warped. Everything is perfect.
Wood crown with their own hands
Any craftsman can come across a situation where there is no drill bit with a suitable diameter at hand. For works that do not require high accuracy and precision, the crown on wood under the socket can be made by yourself for a couple of hours. The list of materials is minimal: metal pipe of the necessary diameter, a “fist” of the door hinge, a drill bit, a screw, a steel plate of rectangular shape.
- In the “fist” with a vice need to drill a hole corresponding to the diameter of the drill.
- On the side of the “fist” at least 1 cm from the edge must be made another hole with a thread, designed for the fixing screw.
- On the edge of the pipe, using an angle grinder, it is necessary to make notches imitating the teeth.
- Weld a plate on the underside of the pipe with a drill hole in the center.
- To assemble the construction, a drill bit is inserted into the “fist” and secured with a screw. The lower part of the drill is placed in the drill bit, and the upper part. in the chuck of the tool (drill or electric screwdriver).
Additional functions refer rather to the power tool that drives the saw blade. Depending on the work process, cooling and dust extraction options may be required. Concrete and metal work can be extremely demanding, making water cooling a necessity, and even a safety feature. For this, drilling rigs are equipped with water tanks and an automatic water supply for the working head. As an alternative, experienced craftsmen recommend that you simply stop the tool at peak times. Dust extraction systems with the possibility of connecting an industrial vacuum cleaner are less often used in systems that include a circular saw for wood, although this solution is theoretically possible. Dust collector justifies itself to a greater extent in the processing of concrete and stone surfaces, the released particles of which not only contaminate the work site, but can also be dangerous for the operator.
