Which is better to choose: a drill or a rotary hammers?
When drilling in hard building materials like bricks and concrete, both the rotary drill and the impact drill can be used. The peculiarity of these power tools is that when they work, the rotation of the drill is supplemented by blows.
When drilling in hard building materials such as bricks and concrete, both a torch and an impact drill can be used. The peculiarity of these power tools is that when they work, the rotation of the drill is supplemented by blows. However, despite appearances, the drill and the rotary tool are very different, e.g. in their main function. In the first tool, it is drilling holes, while in the second, it is chiselling.
The difference between an accelerator and an impact drill
The main difference between the impact drill and the torch is its construction and its application. Whereas a peorator is mainly used for chiselling and drilling and only optionally for drilling, a drill, even with an impact mechanism, is mainly used for drilling.
Technical characteristics of drill and lever differ considerably: in drill, a blow is made by displacement of gear ratchet mechanism, but in lever the blow is made due to compression and rarefaction of air in pneumatic chamber. The hammer is driven by antifriction bearing or crank mechanism.
The rotational speed of the drill is higher than that of the geared drill, as it is designed specifically for drilling, the geared drill mechanism wears out faster when drilling at high speed. But the impact force of the accelerator is greater than that of a drill, which makes it possible to make holes in hard materials faster.
The chuck of these two tools also differs: in a drill it is a quick-action chuck, and in a peorator it is SDS Plus or SDS Max. SDS Plus is available in home models and allows to work with drills and core bits of 30 mm. SDS Max chuck belongs to the professional peorator and allows to make holes up to 120 mm in diameter.
When to use a drill
Handy for making small-diameter holes. The drill is most often used for making holes in metal, wood, and brick. An impact drill can be used for infrequent drilling in concrete, brick or stone.
The drill can be used to screw or unscrew fasteners, and to deburr, grind and polish surfaces using a variety of attachments.
When to use a peorator
A drill is useful for demolition and construction work, including making holes in stone, concrete and reinforced concrete. Long operating time and powerful impact allows it to work effectively virtually nonstop for an entire shift.
With the drill you can cut holes for electrical outlets, pipes and pipes in concrete walls, even with diameters of up to 120 mm.
Most often the peorator is used for demolition of walls, floor coverings, shearing old tiles, window sills, creating new door or window openings. It will also come in handy for shrewdness. creating shallow channels in the walls, where wires or plumbing pipes are laid. All of this is possible due to the chisel mode without drilling.

What do you use a peorator for?
This tool serves for breaking up any materials. It is often used both by tough “pros” engaged in construction and repair on a regular basis for more than a year, and by home craftsmen.
With the help of the peorator you can:
- To drill a hole in concrete, brick, blocks
- remove plaster;
- knock down tiles;
- break off the bricks;
- Make a reamer of concrete walls.
You can’t make repairs or build a house without this tool. It’s easy to work with. it’s fast and has almost no kickback.
The attachments of the device can be:
As for tooling, it can have a tail part of two systems. It is either SDS Max or SDS Plus.
SDS Plus system features four oval grooves for fastening. Two are exposed at the end, the other two are hidden. When the shank is inserted in the chuck, it runs in open slots as if it were a guide. Special locking balls keep it locked in closed holes.

The SDS Max system has five, rather than four, slots for fastening. There are now three open grooves, so the drill is held more securely. This system is most commonly used in professional tools.
The chisel bit is put on the drill when you want to dismantle something. The spade bit is used for cutting through walls for installing cables or for making holes in walls. The nose cone bit helps you make a larger through-hole.
The difference between a peorator and an impact drill
The electric drill and the impact drill. electric screwdriver have a common feature: they are equipped with an impact mechanism, they can drill with a blow. But in this case, what is the best choice for working with dense surfaces: concrete or masonry? Let’s look into this in more detail.
The mechanism of blow in drills is implemented by means of ratchet wheels: they create a reciprocating movement in the chuck. The method is bad in that it gives very low impact energy. In order to achieve any results, the impact drill must be pressed hard against the material to be machined.
Even the cheapest peorator for home will cope more effectively with stone and concrete structures than an expensive industrial percussion drill. It’s about a more advanced percussion mechanism. An electric motor drives the shaft, on which the cylinder oscillating bearing is fixed. Directly in the cylinder itself there is a layer of air that separates the wall and the piston. The latter has a fixed bit that interacts with the tool.
What is better to choose for the house. an impact drill or a peorator
It is not clear whether it is better to buy a drill or a peorator, both tools can be very useful in the household. In general, a domestic hammer is considered more practical and versatile device, it is suitable for drilling and for chiseling hard surfaces. But the device is distinguished by its large size and high price. The capabilities of an electric drill are more modest, but it also costs less, and it takes up less space.
In the repair the electric hammer is more in demand, but on normal days it is hardly useful, unlike a drill
Advice! For small amounts of work it is better to prefer an electric impact drill, it can quickly drill small holes. Buy a peorator is recommended for stitching walls, removing old tiles or making holes for sockets.
What productivity tools have
On sale there are different peorators, manufacturers produce models for domestic use, semi-professional and products for professional use. But even a household tool will cope with the task better and in a shorter time than an impact drill.
- In peoratorov installed more powerful motors and advanced percussion mechanisms, so the tool has a better performance.
- For percussion drills, this index is lower, moreover, it is not allowed to use them in percussion mode for a long time.
If you need a tool for regular work in percussion mode, the question of what is better drills or a peorator for the home, is not even necessary. the peorator clearly wins. The drill is designed for impact and suffers minimal wear and tear through constant intensive use. An electric drill is designed with the expectation that the impact will only be switched on occasionally.
The weight of an electric drill with a hammer is in the range of 2-3 kilograms, so they are comfortable to work long hours without interruption. Everything is a bit more complicated with the torches, because their weight depends on the class of the tool.
|Performance grade||Weight of the machine, kg|
|Lightweight (residential)||4 or less|
|Medium (semi-professional)||6 and under|
|Heavy duty (barrel rotary hammer drill)||6 and larger|
Noticing that the price difference between the drill and the torch is rather big, the first-time masters buy the first one to save money. As a rule, it ends up in disappointment, because with frequent use with impact the device quickly falls into disrepair.
To avoid throwing your money away, buy equipment for its intended purpose! Yes, the peorator is noticeably more expensive, but if you often drilled and chiseled concrete, it will serve you many times longer, and it will be faster and more pleasant to work with. The purchase of an electric drill with a blow should be considered only if you drill concrete very rarely and with narrow drills.
Among the functions of the peorator are the following:
When checking the quality of the torch you should pay attention to the fact that its noise was smooth, without jumps and knocks. Turn the machine on and wait until it has reached the maximum number of revolutions. Now turn it off. The speed must be reduced gradually and smoothly. It is inadmissible to stop the revolution abruptly.
There are professional and non-professional rotary tools. They are differentiated by color. The first respectively are more expensive, but also designed for a large volume and duration of work. So keep that in mind when choosing.
Look at how the device is equipped. You can save money by choosing a peorator with fewer tools included. But eventually, in the future, you may need these parts and spares, and have to buy them separately, which will be more expensive.
- The number of brushes designed for the motor of the torch, which go in stock. If you use the device only at home, the brushes will last a long time, but if you work often, the brushes may soon wear out.
- Plug adapter. This part is designed to fit the drill bit from a regular drill. It will help to avoid additional financial costs.
- Standard drill set. For work only at home, their number, which comes in a set is enough, but if you choose the peorator for professional activity, you will have to buy different types of special drills by yourself.
