Can I Use a Hammer Drill Like a Drill

A real man must be the master of the house!

Mortar nozzle

Masonry mortar

Proportions of masonry mortar

For bricklaying, mortars of the brands M25, M50 and M75 are used.
Proportions sand to cement: M25. 5: 1; M50. 4: 1; M75. 3: 1.
The amount of water is highly dependent on sand moisture, therefore "to the desired viscosity"
Usually, in private construction, no one exactly measures these proportions, everything is by eye.
To improve the plasticity of the solution "specialists from the people" recommend adding detergents from 50 to 100 g of liquid soap or powder to 5-6 buckets of the solution. → But I didn’t add, it was not clear how this supplement would manifest itself in the future..

Sand for the solution must be sieved without fail. over, to use for this the mesh from the carapace is not the best option due to the large size of the cells.

Construction concrete mixer

If masonry with seams of one or less centimeters is required, larger stones create problems during installation, preventing the brick from aligning with the mortar.

I used a mesh of metal wires with a cell of 8 mm, pulling it onto a wooden frame. The frame was set obliquely, and sand shot through it. Before that, I tried to pull a glass-fiber mesh onto the same frame, alas, it was stretched and torn after the first wheelbarrow of sand.

My concrete mixer

The proportion of cement to sand was taken approximately 1: 4. Water was added to the eye in such a way that the solution was not liquid, that is, did not spread on a flat surface and at the same time was sufficiently plastic, allowing you to even out the brick to be laid.

The solution was mixed in a twenty-liter bucket from bitumen mastic, using a drill and a special nozzle. We did not have a concrete mixer at that time, and it is not quite suitable for preparing a small amount of masonry mortar. If you just need a bucket or two at a time, then the AL-KO concrete mixer has more problems than efficiency, because you need to wash it after use.

When mixing a solution with a nozzle for a drill, the same is not all smooth. Neither the drill nor the punch is designed for such a load. They quickly heat up and fail much faster., but trying to mix sand with cement in this way, I don’t feel like going back to the shovel. Still, the nozzle on the drill whips the mixture much better, and when kneading you will not get tired at all.

When using nozzles for stirring the solution, one must be prepared for the fact that this product will break quite quickly. During the season, the corollas in two nozzles were worn off and collapsed, and two more broke off the mountings in the SDS cam. They are not expensive and considering that they work in the sand as in sandpaper, this is not so scary. In the end, the Chinese drill, which was burnt down, was more upset, although "chёsu" Of course we gave her for the construction. A 750 W DVT puncher seemed somewhat more tenacious, although it also had to change the bearing and brushes.

In the end, I found some compromise using small diameter nozzles. Let them interfere longer, but the load on the drill is not so big, there is a chance that the surviving drill will reach the end of construction.

During exercise repair work very often it is required to use a wide variety of manual, automatic or semi-automatic operations: chiselling, drilling, polishing, grinding, cutting, welding, etc. It is known that for each repair operation there is a specialized tool.

It is not always required to perform these operations equally often: sometimes it happens that a repair operation is relatively rare or even once. What to do then? Run and buy the right one building tool for single use? Take from neighbors, acquaintances or friends "for a few days"? Of course, there is a desire to use the tool already available in the work to replace the missing one.

The most common tool used in repair and construction works, is a punch. This power tool is available to almost everyone who at least once in their life has encountered repair. On the other hand, one of the most rarely used tools today is construction mixer, intended for mixing various construction and repair solutions. The reason for its rare use in repairs is a small, as a rule, quantity of a solution stirred at one time (varnish, glue, etc.), in which it is quite possible to do without mechanization: stir manually.

Nevertheless, there are cases when the use of electromechanical stirring is simply necessary: ​​a very viscous medium, a large volume, harmful environment, a large mass of one batch, the specificity of the process (uniformity, very fast or very slow shaft rotation, their combination), short time requiring high performance etc.

Construction mixer. how to make a mixture of high quality?

In all of the above methods, it is with a punch that they try to replace the mixer with stirring. How justified is it? Is a rotary hammer capable of performing a function not characteristic of its primary use? We will try to answer all these questions in this article.

As known, modern rotary hammers able to work in at least two modes: drilling and drilling with impact. It is also known that for drilling into a standard type cartridge Sds an adapter (optional chuck) is inserted under the drill. Therefore the nozzle for mixing from the mixer It’s easy to insert. Further. Quite a lot of perforators have a built-in mechanical gearbox that allows you to work at different speeds. Then, obviously, all the salt of performing a new function for the hammer drill is concentrated in its drive.

All hand punchers,
as well as mixers, they are equipped with a universal commutator motor, the shaft rotation speed of which is controlled by reducing or increasing the supply voltage. Then the question comes down to the characteristics of these engines, the main of which are the maximum number of revolutions of the motor shaft, the power on the shaft and the torque on the shaft.

Consider the work of a puncher
separately for two types of mixed media: weakly viscous and highly viscous. Stirring a slightly viscous solution requires a small torque and a different speed of shaft revolutions. It is known that single-speed rotary hammers are controlled by the force of pulling the trigger, usually located in the handle of a power tool. Using different pulling force of the trigger, we smoothly change the shaft (spindle) revolutions: with low pressure. low revolutions, and with strong pressure. high up to the maximum.

The problem is that the speed lock, as a rule, only works when the trigger is pulled fully, that is, at maximum engine speed. When mixed, this is very inconvenient. The output, obviously, consists in the operation of such a tool through a step-down transformer (you can use LATR), the power of which must exceed or be equal to power consumption of the punch. In this case, the work of a puncher as a mixer has every chance of success.

In addition, there are currently models of rotary hammers with adjustable speed control, which can also be used as mixers. You should always remember that the lower the supply voltage of the hammer drill, the lower the efficiency of such a motor.

The situation with highly viscous media is more complicated. To mix them, as a rule, low revolutions and high torque are required. If the speed can be adjusted by connecting a step-down transformer to the punch (as in the case of low-viscous media described above), this will not work with torque, since when the voltage from the transformer decreases, the torque on the shaft drops along with the shaft speed (smooth characteristic).

It follows that work through a transformer (at low voltages) is advantageous only in the case when the punch torque exceeds the required torque for mixing the medium, and this is not so common. Otherwise, the puncher will need additional cooling (especially at low shaft speeds, at which the fan built into the engine does not create more or less normal air flow to the collector of such an engine), since otherwise protection against overheating will work (the engine temperature sensor will turn off the power of the punch).

In addition to additional cooling, you can use some other methods: reducing the diameter of the working part of the nozzle (This is one of the most effective ways to reduce the required torque!), Reducing the diameter of the tank and / or the height of the mixed layer. The ideal option is a multi-speed rotary hammer. With it, you can work with viscous solutions at the first speed at low shaft speeds and at the second with weakly viscous at high speeds.

Consider hammer work in relation to high-speed mixing to obtain foamy solutions or finely divided suspensions and / or emulsions. The standard maximum work of the puncher is approximately 1000. 2000 rpm., Which is quite enough for most stirring in normal mode.

However, get high speed with the help of such punchers without the use of external mechanical gears it is impossible, since the engine is limited by the supply voltage (220 V). For rotary hammers with an integrated gearbox, the maximum shaft speed will be equal to the highest gear gearbox and at maximum supply voltage.

Thus, hammer drill It can be used as a mixer. For viscous media, an additional step-down transformer may be required, although this is not necessary. For highly viscous media, additional engine cooling or more frequent than usual pauses during mixing may be required to cool the engine. With high-speed (very fast) mixing, exceeding the maximum rotational speed of the hammer drill shaft, an additional external mechanical gear may be required

The advantages of using a drill mixer for construction work

For the preparation of cement, paint, glue and other building mixtures in large volumes, nozzles on a drill for mixing the mortar are best suited. They are a metal rod on which the impeller is fixed. a curved metal or plastic rod (whisk).

Before choosing mixer for drill, it is necessary to determine its important parameters, which depend on the specifics of the planned work.

Main characteristics

How to mix building mixtures?

However, it should be remembered that a key of a suitable size is required to replace the nozzle. While the other type of shank. hexagonal. can be clamped with a conventional three-jaw chuck.

  • Impeller Material affects what substances can be mixed using one or another mixer nozzle. Mixers, the impeller of which is made of strong steel, as, for example, with Metabo 631963000, are recommended for working with heavy building solutions: cement, putty, insulation materials, etc. Mixers with an impeller made of plastic, such as, will perfectly cope with cooking more light solutions, such as paints. In addition, the plastic will not damage or scratch the walls of the container in which the mixing takes place.
  • Agitator length affects the depth of the solution, which will be mixed using a specific nozzle. Manufacturers produce tooling of different lengths. However, the standard dimensions are 400 mm, for example, Encore 27406, and 600 mm, like y). But the Profi for drills FIT IT 04260 has a length of 600 mm and is suitable for significant volumes of mixtures.
  • Diameter. the processing time of the entire volume depends on it: the larger the diameter, the faster the mixture will be stirred. Our website presents a wide range of models with a diameter of a whisk for a drill from 60 mm, as with Encore 27414, to 220 mm, like a nozzle "EXPERT" for mixers Bison ZMRN-2-220.

    DIY drill from the mixer

    Both the mixer and the electric drill are far from essentials. Not everyone can afford to keep at home both. But even if you can boast of having an electric drill at home, most often it is a powerful kilowatt apparatus, which is convenient for drilling walls. But it’s hard to drill radio cards or repair shoes with it, right? Therefore, I had the idea to make a special nozzle for the mixer, with which now you can not only cook omelets, but also drill a hole in an inaccessible place.

    The adapter to the drill is inserted into the socket of the nozzle "high-speed knife." If you have a rubber joint between the mixer and the nozzle, you will have to redo it. For the effort that he is able to transfer is not enough even for the coffee grinder to work. A square is best for connecting, but a hexagon is also good.

    The drawing shows the dimensions of the nozzle parts for the mixer "MP-2E" produced by the Minsk Electrical Equipment Plant, but due to the similarity of all models of mixers, the correction will be very slight. I took a cartridge from a hand drill. Drills with a diameter of more than 5 mm should not be counted even when drilling wood (after all, the power of the electric motor of the mixer does not exceed 100 W), so if you can choose a chuck, choose the smallest possible size.

    DIY manufacture of a mixer drill

    Parts 3 and 4 require manufacturing on a lathe; if there is no head of the right size for part 3, the groove for the hexagon will have to be milled. In the case of the complete manufacture of part 3, a slight improvement can be made, which is as follows. To exclude an additional friction surface between 3 and 4, make a selection for the hexagon with a slope of 5-6 degrees relative to the horizontal axis. This is necessary so that the head, sitting on the hexagon, engages with it when moving and is jammed by friction. In this case, there will be a small gap between the head and the sleeve, which will prevent additional heating of the unit and the associated loss of power.

    Part 4 can be made of any structural steel, but if you can find a piece of polyethylene of suitable sizes, the design will only win. If structural steel is used, a through hole should be provided in the sleeve to lubricate the shaft; the polyethylene sleeve should be lubricated with solid oil. Usually the quenching of the cartridge shaft is superficial, and the MB thread should be cut easily. The nozzle is assembled as follows. A sleeve is put on the cartridge shaft, then the head is screwed.

    Choose a drill mixer

    The nozzle assembly on the MZO thread is screwed to the mixer.

    The use of the nozzle is also supported by the fact that the mixer, unlike most electric drills, has a smooth adjustment of the rotational speed, which creates additional comfort during operation. By the way, maybe you have an old photo enlarger lying around? In the conditions of the “Kodak” victorious advance, you hardly need it already, and its tripod can be adapted for a drilling machine. A tripod with a gear rack from the “UPA” enlarger is especially convenient. The adjustment flywheel moves the drill as smoothly as on a drilling machine. If you have a “Master” low-power drill, you can place it on a tripod.
