Drill mixer: types, advantages, disadvantages and tips for choosing

A drill mixer is a great helper for any builder. Such devices have a rather powerful motor and two ergonomic handles, which are necessary in order to hold the tool while mixing mortars and mixtures. This is a convenient mechanism that combines several important functions at once.

The construction sector of the industry does not stand still - every year new compounds appear that are used for the construction of structures, minor and major repairs. Both glue and plaster and many other materials go on sale in the form of a powder, which must be diluted with water in order to make a full-fledged composition out of it.

In order for the components of the mixture to mix as well as possible and to form a homogeneous working mass, it is necessary to choose the right tool. For example, if you can mix wallpaper glue with an ordinary stick, then which method will be ineffective for cement mortars and putties, especially if you need a solution in large volumes.

Many users resort to a hammer drill in such situations., which has the necessary rotation capability; Nevertheless experts do not recommend using this method, since the hammer drill is initially focused on loads in a different plane without any influence of radial forces. Of course, it is possible to mix a small volume of solution with its help, but in large quantities you run the risk of simply disabling your instrument, which, by the way, is quite expensive.

Such devices are optimal both in everyday life and during professional repairs. Unlike the hammer drill and the usual drill, they have a stronger bearing, in addition, the mechanism is equipped with a powerful gearbox, which is protected by a particularly durable metal case. Thanks to this configuration the device can work even at the lowest rpm.

An important plus is the fact that such construction mixer can simultaneously perform the function of surface drilling, that is, in fact, it is a 2-in-1 device.

The drill mixer is used for large-scale repair work; the user usually holds it in his hands when mixing the solution, because the device has ergonomic handles that make the operation of the tool less time consuming. If the engine of the device has a power of more than 1 kW, then a special gearbox is built into it: it is suitable for use not only at the very first speed, but also when changing from the first to the second.

The first is used to compose thick dense mixtures, for example, mastic, and the second - for gypsum and cement. Stirring paints and varnishes and other liquid substances with a minimum torque is also permissible at second speed.

These are very important options: thanks to them, when removing the device from the resulting composition, the torque remains in its original position and no splashing of the finished mixture occurs, as is the case with many other mixers.

Such drills, as a rule, have different configurations. Usually they come with several types of attachments, which can have several shapes.

• Right-hand spiral mixing nozzle - used for such solutions that have a very viscous structure. These include cement, concrete, and various kinds of plasters and glue. Such a nozzle mixes the solution, as if pushing it upwards, mixes the composition at the top, and then drops back.
• Left-hand spiral nozzle optimal for mixing paints and varnishes. Here the principle of operation is reversed: the mixture is pushed from top to bottom, where it is stirred and rises back.
• Screw nozzles allow mixing light compositions.
• Crosspiece - a more specialized nozzle, it is used in cases where it is very important to prevent air from entering the container with the mixture.

The main advantage of the drill mixer is its multifunctional use. On the one hand, the tool is classified as a drill, therefore, in addition to mixing mortars, it can be used to form holes in surfaces of various types, even the hardest and most dense ones. On the other hand, a drill of this type belongs to the category of low-speed ones, therefore it cannot replace a drill by 100%, but at the same time, it is precisely low speeds that make it possible to mix even the most dense compositions.

It's obvious that such a structure cannot be used in industrial volumes, its power and design features will not be enough to cope with intensive use. But with the solution of small household tasks for minor repairs and decoration of an apartment or a private house, she will cope in full.

Depending on the principle of operation, there are three types of tools:

• drill mixer;
• drill mixer with one whisk;
• device with two rims.

A conventional electric drill mixer is a low-speed, impact-free type. The power of this tool ranges from 500 to 2000 W, there are 2 comfortable handles, a fairly large cartridge with a diameter of up to 16 mm.

Two-handed models are divided into options with a single whisk or with two, the difference follows from the name: mechanisms with two whisks mix even the most viscous mixture, they are equipped with a rather powerful gearbox and easily cope with solutions of a wide variety of consistencies - from light to concrete.

Drill mixers of the following brands are the most popular among consumers.

• Fiolent Is a Russian-made product that is optimal for mixing the thickest and most viscous compositions. The power of the device is 1100 W, and the speed is 600 rpm.
• Rebir - the most popular low-speed drills are produced under this brand. Selected models from this manufacturer have exceptional performance characteristics: power up to 2000 W and rotation speed up to 500 rpm.

• Interskol - offers a wide range of drills-mixers, the power of which reaches 1050 watts. Such a tool is optimal for mixing any building mixtures, even concrete, and also for drilling: for example, if you put a special drill for wood in it, you can get a hole up to 1 m long in a matter of seconds.
• ZUBR Is one of the most demanded brands on the domestic market. The models presented in the range of this manufacturer have exceptional power parameters - up to 1200 W - and rotation speed (up to 850 rpm).
• Makita Is a well-known Japanese brand that is in demand all over the world due to its quality and reliability. It is noteworthy that all models of this brand, in addition to excellent technical characteristics, are also distinguished by practicality, because they consume much less energy than competitors.

Experts recommend to adhere to the following technical and operational parameters when buying a drill mixer:

• product weight - in the range of 2.7-4.5 kg;
• power - 620-110 W;
• rotation speed - up to 1050 rpm;
• torque - 70 N / m.

If you wish, you can make a construction mixer with your own hands. For this, you need to use the most ordinary drill as a drive, and any product with a hex shank is suitable as a nozzle. Such a device is quite easily fixed in the drill chuck, the main thing is that the dimensions of this hexagon correspond to the minimum chamber size that can be placed in the chuck.
