How much revolutions per drill?
Typically, the maximum rotation frequency of the drill cartridge within 3,000 revolutions per minute. Below 3000 rpm there is usually an electronic adjustment, and it is very difficult to achieve a powerful moment of rotation of the cartridge in such droplets. In some more expensive models, the revolutions are reduced to 270, 350, 400 or 700 mechanically.
To tighten the screws, 200-400 revolutions per minute (rpm) are enough, for drilling with certain diameters it is necessary to up to 1200-1500 rpm. As a rule, screwdrivers will be drilled in unstressed mode, but there are models with a shock mode of drilling.
Drill mission, the difference from the peorator and electric screwdriver
When choosing a device, it is necessary to first take into account the scope of use. The tool can be used both in the apartment and in the country. The device will also be indispensable in the garage and a small workshop. You can use the drill for the following purposes:
- Drilling holes in concrete and brick walls;
- Drilling in wooden surfaces;
- Screwing and dismantling the bolts;
- Drilling metal.
Depending on the power of the device, you can drill any surfaces. Therefore, such equipment will become indispensable during the repair.
Important! For universal use of the tool, often users purchase additional nozzles.
An electric screwdriver, unlike a drill, can unscrew the bolts with different speeds, and can even cope with the encouraged copies. Some models go with a shock function, so they are often used instead of a penetrator. However, it must be borne in mind that for prolonged drilling concrete the drill is not used. For such purposes, it is necessary to purchase a peorator. The difference between the devices is that the drill is drilling, and the peorator hollows and allows you to get large holes.
Question from the reader
The reader Alexander turned to me in the mail, with the following request:
Good evening. I stumbled upon your blog, where you repair the Bosch drill. I have a similar problem, only I have almost no relation to electronics. By stupidity, the trigger of the drill Bosch GSB 1600 Re was disassembled. Everything worked wonderful before, somehow gathered, now a smooth start does not work. Perhaps in the wrong sequence and I insert spare parts in the wrong place. I attach a photo of the disassembled. I hope for help, the drill is good.

What power should be a shock drill?
When choosing a shock drill, pay attention to the power of the tool. So that the impact function is normal, this indicator should be at least 800 watts. Also pay attention to the reverse rotation function and the presence of a safety coupling.
The torque is defined as the impact on the solid body of the force during rotation. For example, you need to tighten a bolt with a hexagonal head. For this task, the key is intended to be attached to the force. The work of this force and the length of the key, and there is the very torque.
What is the difference between an electric screwdriver and a drill?
The next difference that affects work is the behavior of the tool after turning off. The drill is inertial, so after turning off the rotation continues for several seconds. The scorchor stops immediately. The cartridge of the device for working with fasteners rotates more slowly than that of a drill.
The torque of the engine is a work of power on the shoulder of the lever to which it is applied. If you remember, then the force is measured in Newtons, but the lever shoulder is measured in meters. Nm. 1 nm is equal to the force of 1n (Newton), which is attached to a lever of 1 meter.
Which is better to choose an electric screwdriver for the home?
This allows you to perform labor.Intensive drilling, twisting or mixing. At a reduced frequency, there is no overheating of a large diameter equipment, and to tighten short screws is more convenient at low speeds. At the second speed: you get the maximum rotation frequency.
What torque should have an electric screwdriver?
The values of the torque in the household instrument, which are used at home for one.Time tasks, is quite enough within 10. 15 nm. In professional two- and three-speed batteries, this parameter exceeds 130 nm to easily cope with the drilling of very solid materials.

How to choose a peorator. An article to help when choosing the best peorator
At first glance, the peorator is a more specialized tool than the drill. It would seem that it should be less in demand for home use. However, comparing the volume of their sales, there is no significant advantage of drills. Why is that? After all, a powerful shock drill can beat the wall in the same way, many think.
So, not so. In this case, the correct choice of the tool for solving a wide range of household problems should not be based on the external similarity of functions, but on assessing their effectiveness and understanding of fundamental differences in the method of their implementation.
Definition of goals and selection of means of achievement
It is not necessary to have both devices at home with similar functionality, if you understand what their difference is from each other. The drill has the main action. Rotational, and deterrence is an auxiliary function. Therefore, all its constructive is aimed at drilling holes, milling, grinding, polishing of various surfaces, screwing/twisting medium-sized methysis, mixing solutions, varnishes, paints-you only need to insert the corresponding drill or special nozzle into the cartridge and everything will twist, will be blown away. For maximum use of the rotational properties of the drill, the main parameters are selected: power, moment, The number of revolutions.
And her shock capabilities are only an addition, allowing, again, to drill concrete and brick. In this case, the reciprocating movements of the winning drill are organized by slipping of the oblique teeth of two rotating ring couplings, one of which is tightly attached to the cartridge drive, and the second to the housing plate. As a result, the energy of the blow is small and depends mainly on the strength with which the operator presses on the drill and only to some extent. From its parameters.
Completely different priorities are observed if you choose a peorator as a home tool. Its main task is the shock impact on the appropriate nozzle: Boer, chisel or Peak, with which you can make holes in the most durable material, knock down the unnecessary or punch the right. Window opening, ventilation duct, recesses under the sockets, wires, etc. And drilling is an auxiliary type of shock tool. Although, according to many experts, he can replace a drill in almost everything, except, perhaps, the functions of an electric screwdriver.
The principle of the formation of a blow in the peorater is fundamentally different from that in the drill. Here is a node that transforms the engine rotation into the back of the drill, acts on an intermediate element-a massive boiler, and it already hits the shank of the drill. Thus, the case is not strictly connected with a hollowing nozzle and does not participate in creating a blow, the effectiveness of which in this case depends only on the characteristics of the device, and not on the strength of the operator.

Structurally, the system can be implemented in the form of a crooked-shaped mechanism or using a “drunk” bearing. Further, the linear force either directly affects the spring.Loaded striker, or through pneumatics. The compression and vacuum creates a piston that is with a brisk in a hermetic cylinder. It should be noted that by choosing a device of pneumatic shock mechanism, you get a more effective and reliable tool with high efficiency and long service life.
The drill is intended for grinding-distilled, mixer and assembly works of a wide spectra. Its shock functions are auxiliary, implemented in a simple but not very effective way, which limits its use to solve serious problems in concrete, granite and brick structures.
The pediatricrator is originally “sharpened” on a blow, the principle of the implementation of which is based on the optimal transformation of the electrical parameters of the engine into mechanical energy of the impact. At the same time, its acquisition solves almost all issues related to drilling, plus use as a mixer is an order of magnitude more effective than a drill.
All the same “pro” or “for home”
The question is not idle, since the purchase is not cheap and, most likely, several years ahead. Therefore, your desire to choose the best peorator among the proposed variety of models is quite understandable, although not entirely true. The approach based on the determination of the list of upcoming work, the number of finances, the analysis of the reviews of friends and acquaintances will be rational, after which you can make a more or less conscious selection of tools.
A professional peorator, of course, is more reliable, has a power of more than one kilowatt, an energy of the blow of up to 20 J, can pierce a hole of more than 50 mm in concrete and at the same time work for several hours without a break. But it will hardly be in demand for the repair of the apartment, plus a large weight and considerable cost. In fact, “minus” in relation to homework. Household models in their characteristics are quite suitable for solving periodically arising problems with any repair and even small construction.
Simple rule: if the choice of the peorator is due to the need to earn money, then only a professional tool is needed. For home, country, garage repair and construction work-enough domestic class.
We pay attention to the main parameters
After you have already finally determined what type of peorator you need, do not rush to buy to the nearest tool store, since in the framework of even one category there is a huge assortment of products that differ in their characteristics. Know and understand how significant their influence on functionality is extremely important.
Home drill. How to choose the best option
In the arsenal of a home master, there is simply such an instrument as a drill. Agree that you often need to drill something and just without a drill nowhere. Hang a shelf, tighten the self.Tapping screw, drill metal or wood. All this is done using a drill. How to choose a tool, what should be paid to the home master when buying. Several useful tips.
The entire power tool is divided into 2 types. Professional and household. The question arises. What is the difference and which drill to choose for the home, household or professional? In a big account, the difference between a household and a professional tool is a mode of operation, a household drill can work without distracting about 15-20 minutes, after which you should take a break, give time to cool down the engine. A professional drill can work with a full work shift without resting at all. That’s the whole difference.
Now ask yourself the question. Will you work at home 8 hours without a break?
Of course not, then why buy professional, for home needs there will be enough household instrument. Of course, if you have a certain amount for the purchase and fit into the price of a professional one-then it is better to take a profile for a senior, it will serve you for a long time, and when working in the mode of “household” use, such a drill will work for many years.
Of the companies producing household tools, first of all, brands should be noted:
Skil. Bosch branch, segment of household tools. Skil drills. Reliable, strong, durable, even suffer intensive loads. Users reviews are positive, the guarantee from the manufacturer is 2 years old.
Black and Dekker. A fairly famous company, is engaged in the production of only household tools, orange. A distinctive feature. High quality, 2 years warranty, reviews of grateful users only positive.
“Zubble”. The Moscow brand gaining popularity is positioned as a domestic instrument, but the assembly is the Chinese. By the way, the quality of the drills is not bad, they give a guarantee for 3 years, and this is a lot. So the manufacturers are sure. By the way, if you had a duck of a hurricane company, then the “bison” is a continuation of the “Uraganovo” line. Hurricane drill is just super, all my friends have such, it can be repaired, it is not killed.
Stern (Stern) is the most famous tool, such as a manufacturer Austria, but this is pure China, and of a low quality. However, a very low price has gained popularity to him, many people buy Stern drills for home and work with them. Of course, if you follow the rules and not overheat the tool, then even Stern will serve for a long time.
DVT, Hammer, Prorab. A Chinese tool of approximately one class, the most advertised foreman, but the quality of everyone is approximately at the same level. Low also allowed them to win a cheap tool segment, for the home, of course, more and no need.
Well, perhaps, and everyone ran through the brands, now let’s look at what you should first pay attention to when choosing a drill for the home.
Of course, the most important parameter is power. The optimal power for the home is considered to be 700-800 watts, it will already be a powerful drill that can be tightened by thick self-tapping screws. Indeed, in addition to the main functions, the drill performs a bunch of auxiliary ones. Self.Tapping screws are spinning it, a solution, cement, varnish and paint, etc. Interfere with it. Therefore, if the drill is powerful. You can knead putty, I use special mixers for paint, putty or glue. However, over 800 watts drill will already be heavy and bulky, therefore, for example, it will already be inconvenient to twist the screws. Therefore, 700 watts is a golden middle for a home drill, you can do all the housework.
Why is it necessary to adjust the revolutions on a home drill? First of all, so that it is convenient to drill. After all, at first you flinch at small speeds and only then press it stronger. It is simply impossible to outline the drilling point on the metal without adjusting the revolutions. Also twisting screws. If a drill is without adjustment, then it immediately starts at maximum speeds, so it is unrealistic to tighten the self.Tapping screw. Revolutions can be adjusted both by pressing the start button and a special regulator on the start button.
An important feature, the presence of a reverse on a drill is mandatory. Why do you need a reverse? First of all, reverse is used when twisting, twisting screws. If in order to save money you use a drill as an electric screwdriver, then you need to buy a tool with a return. After all, how to unscrew a wood self.Tapping screw if there is no reverse? No way, so take it with a reverse. The return switch is located directly above the start button, on the right and left.
Most often, most of the drifts are already driving, that is, at the top of the drill there is a switch between shock and drilling modes without impact. Very often a shock drill is confused with a peorator. Difference. The penetrator has an electric blow, more than ten times, and the drill has a blow due to a sprocket from getting teeth on the teeth. The shock drill can only be drilled brick, the concrete will not take. But for drilling concrete you already need a peorator. If you initially take a drill for drilling brick, then take more powerful, watts for 1000, this will help to strengthen the blow. By the way, the stronger you click on the tool when drilling with a blow, the stronger the blow. When drilling metal and wood, the blow must be turned off.
