Drill mixer
An irreplaceable tool when carrying out repair work, for mixing building mixtures, mortars, mastics, etc. Due to the high loads, more powerful bearings are provided in the design. The gearbox is also reinforced and made in a metal housing. Feature - long-term operation at low speeds, as the mixtures are stirred at a speed of no more than 500 rpm. The motor power reaches 1600 W. torque up to 70 N / m. Weight - 6-7 kg.
The tool has a narrow specialization. However, it remains a drilling tool. For example, it can be used as an earth drill.

Metabo BE 10 SSBF
Metabo BE 10 SSBF
The drill is very powerful, extremely easy to use and compact. Designed for drilling holes with a fairly wide range of diameters:
- in metal - up to 10 mm
- in wood - up to 20 mm
The use of a keyless chuck provides good fixation and high speed of tool change. The BE 10 SSBF has a reverse system. In addition, due to the smooth start-up and low weight (1.1 kg), the drill can be used as a screwdriver.
Advantages:
- efficient operation at high gearbox loads
- Metabo's exclusive Variospeed system. Allows you to adjust the torque by pressing the trigger
- convenience of work at high altitudes. Achieved due to the convenient suspension system of the drill on the belt
- the presence of a rubber pad on the handle of the drill. Allows you to conveniently position the tool in your hand when drilling in various positions
Disadvantages:
- low power output (240 W)
- high noise level when operating at maximum speed (up to 91 dB)
- difficult access to the brushes, which requires disassembling the drill

Recommendations: how to choose a drill for home
Before choosing a drill, you should decide which class of tool you need - household or professional. And then make the final choice of the device. For home use, a household unit will be enough, especially if you have to use a drill infrequently.
When choosing a drill, keep in mind:
- Power - home drills can range from 500W to 1,000W. This value makes it possible to work with metal, wood, concrete and other materials.
- The presence or absence of an impact mechanism - for work at home, it is desirable that the "blow" was, since often you have to do a variety of work, where you need to check both walls and other very different materials.
- Power supply - can be mains or rechargeable. At home, the first option is quite suitable. True, it is better to stock up on an extension cord just in case.
- Rotational speed - usually this figure is 500-1500 rpm. All drills have a dedicated rotational speed control knob that should be used when working with different materials.
- Hole diameter - these indicators can be found in the model passport. Knowing the maximum diameters is necessary so as not to accidentally burn the tool on the very first working day.
- Chuck Type - For home use, it is best to use a metal key chuck that holds the drill securely. True, in this case, you need to be careful not to lose the key to the cartridge itself.
When choosing a drill for home use, you should take into account the frequency and intensity of work, since the model is household, then it assumes a short-term use
If the work is to be done for a long time, the drilling machine must be periodically cooled by unplugging it from the network. It is especially necessary to do this if heat has gone from the drill body or the smell of burnt insulation has become audible.
By the way, the speed of rotation or the number of revolutions performed shows how the tool will behave when working with various materials.The higher this indicator, the higher the capabilities of the drill. Even if the power of the drill is small, the high rotational speed will override this. You can do a little test to make sure of this.

How to choose?
From all the variety of Russian and foreign-made drills on the modern market, choosing the best option is not so easy, especially if you are a non-professional builder
Pay particular attention to important characteristics
Power parameters
In most cases, the power of the instrument varies from 400 to 900 watts. There are also more powerful mechanisms, but they are applied in the professional field. The higher the power setting, the higher the torque required to drill deep holes. At the same time, with an increase in this indicator, the weight of the instrument also increases, be sure to take into account the physical characteristics of the person who will work with it. If this is a flimsy man, then he may not be able to hold the overall mechanism in his hands for a long time.
Another parameter that you need to pay attention to is the rotational speed. Typically, the operating manual indicates the rated speed, calculated at idle speed.
It turns out that the larger it is, the cleaner and the final hole will turn out, and even for a low-power unit, this parameter opens up great opportunities. In addition, higher speeds should be selected for impact mechanisms, for example, if you plan to use devices for grinding and polishing. But to work with hardware, speed is not required, here 450-500 rpm will be quite enough.
Assistive devices
The reverse allows you to unscrew the fasteners, and also to free the stuck equipment from the "captivity". The multi-piston reducer is used to increase the torque and thus reduce the gear. Usually, the first speed means higher torque and low frequency, and the second, on the contrary, means higher frequency and low weight. Such tools are much more effective than all the others, since the finishing power does not change with the change in the speed parameters.
Pay attention to the features of the cartridge. We have already mentioned that they can be conventional and quick-release.
The first type is considered more reliable, but is usually installed in professional tools. For domestic use, it is better to give preference to quick-clamping mechanisms, which allow you to change the drill if necessary in a matter of seconds and without any effort. If you have a tool with a metal gear case in front of you, then this clearly indicates that the drill belongs to the professional category. Due to this design, the heat dissipated for the moving parts is more efficient, and thus the required durability of the assembly is determined. However, the result will inevitably increase the weight of the product as a whole.
If you buy a fairly powerful drill, then it will be useful to have such an option as a smooth descent: it accelerates the rig rather slowly and completely eliminates starting jerks. There is no room when choosing a drill little things - every detail counts, so take a look at what the tool looks like. When examining the tool, shake it a little, make sure that the rubberized handle is comfortable, feel all the calcinations - preferably, their surface is grooved. Enjoy the accessibility of all control systems and the ease of switching buttons.
Inspect the power cord. Firstly, you need to make sure that it is intact, and secondly, that its length matches the characteristics of your room. If possible, give preference to models with an anti-lock clutch: it protects the mechanism from burnout in the event of a mechanical collision, and also protects the operator from the risk of kickback. The most expensive products usually have an anti-vibration system.
Look for a spot light that illuminates dim work areas. It will not be superfluous to purchase a tool with a dust collector.
In this case, the tool will independently collect dust that appears when interacting with concrete and stone bases. Pay special attention to the configuration. Many manufacturers sell a charger, a spare battery, a set of drills and other elements along with an electric drill.If you are sure that all this will be useful to you, it is better to buy the maximum sets right away: it will be cheaper than if you then buy all the necessary additions separately.
