Is It Possible To Interfere With The Solution With A Perforator

Drill for mixing mortar
Drill for mixing mortar Hello everyone! Construction or major repairs almost never do without work, for which it is required to prepare a working mixture of dry components and

The main types of mixers

The choice of a construction mixer primarily depends on the amount of work and the frequency of use.

is it possible to interfere with the solution with a perforator

By the type of drive, the tool differs in:

  • Manual. The device has a special attachment and is powered by human muscle power. Suitable for mixing small portions of the working mixture.
  • Electric. It can be a drill or hammer drill with a special attachment, or a specialized device with a set of attachments.

It is used in the course of large-scale construction and repair works.

The tool is available with one or two screws. Twin screw models are characterized by higher power and higher productivity. The nozzles of the twin-screw mixer rotate in different directions, due to which the position of the mixer is stabilized and it is more convenient for them to work.

By power, construction mixers are divided into household models (the main part of perforators and drills, as well as low-power mixers) – up to 1 kW, and professional tools – these include perforators and specialized mixers with a power of over 1 kW. The power of specialized units designed to work with heavy solutions is 2.5 – 3 kW.

Preparation of concrete by hand and using a drill mixer.

Household models are equipped with handles in the form of staples – ring version. For heavy-duty professional models, the handle is T-shaped. If the coating is anti-vibration and anti-slip, this makes the device more comfortable to use.

The package bundle also influences the choice of a suitable model. The kit includes a nozzle with a device for fixing it. The attachment is done in different ways.

Threaded connection. The nozzle is screwed into the spindle with a threaded upper part. It is used in a professional tool as it provides a secure fit.

Jaw chuck. It is used for drills – mixers and household electric drills. A special key is used to fix it in the chuck. Suitable for liquid, light and medium viscosity solutions.

SDS connection. Designed for rotary hammers. The attachment must be of a suitable design. It is used for mixing adhesives, plaster and putty solutions.

Keyless chuck FastFix. The system allows you to quickly change the attachments by analogy with a screwdriver, but is not designed for frequent work with concrete mixtures – the edges of the cartridge are erased. If reverse is used, there is a danger of the tip loosening.

Morse taper. The most reliable option, it allows you to work with any type of compound. Used on professional models of the instrument.

In addition to buying the construction mixer itself, you need to take care of the choice of nozzles. Stirrer – propeller suitable for liquid formulations. Nozzle – a crosspiece with vertical blades is used for mixing viscous and heavy mixtures.

The spiral left-sided (moves the mixture down) and right-sided (moves the mixture up) is used for compositions on a gypsum or cement basis and "light" concrete. The double-sided screw is designed for liquid and non-viscous mixtures. The universal auger is suitable for all types of mixtures.

What to look for when choosing

To choose the right construction mixer, pay attention to the characteristics and functionality of the models.

Weight. From 2 kg (for a drill with an attachment) to 15 kg (professional tool). Semi-professional models weigh about 7 – 9 kg.

Speed ​​control. The mixer is designed to prepare suspensions of various viscosities, in order to cope with work regardless of the characteristics of the composition, it must be equipped with a built-in electronic mechanism that regulates the engine speed. Without a regulator, the operating mode of the device during mixing will be violated due to a change in viscosity.

Torque. The higher the indicator, the more dense the mixture it can work with. Household tools with a power of up to 1 kW and a torque of up to 20 Nm allow you to prepare grinders, putties, coloring compounds, tile adhesive, plaster mixture. Concrete mixes are handled by a semi-professional and professional tool with a torque of 50 – 100 Nm.

Speed. Low power models are single speed. The powerful tool is equipped with a gearbox – the second speed is designed for the preparation of liquid solutions.

When deciding which construction mixer to choose, pay attention to the additional options of the models, in particular:

  • Smooth start. In this mode, the engine starts without jerking, so that the components of the mixture are not splashed and scattered to the sides. By reducing the peak load, the service life of the power tool is also extended.
  • Electronic motor protection system. Automatically shuts off the motor when the brushes are worn out, when overheating occurs, and stops work if the loads have reached critical values.
  • Hand protection. The handles are designed in such a way that it is convenient and safe to work with the mixer.

Rotary hammer care tips

The service life and the overhaul interval directly depend on how timely and competently the complex of works on the maintenance of the perforator is performed. Much attention should be paid to the lubrication of the gearbox, especially if work is carried out with concrete structures, the drilling of which is accompanied by the formation of a large amount of dust.

A good protection against it can be the use of a vacuum cleaner; many models of power tools are even equipped with special devices for fixing the hose. It is also necessary to take into account that when operating at low speeds, the equipment quickly heats up, therefore, constant monitoring of the rest and work mode is required.

After the end of use and disconnection, it is recommended to clean the tool with a soft cloth from dirt. You can use soapy water if necessary. Pay particular attention to the cleanliness of the ventilation openings. It is equally important to regularly carry out preventive inspections of equipment.

Also, before starting work, it is imperative to lubricate the nozzle shanks. This is to avoid excessive stress on the drill barrel due to friction. If such work is not performed, then it can "result" in expensive repairs.

How to work with a puncher: 7 nuances that are important to know

Even small repairs, not to mention professional construction, are not complete without the use of a hammer drill. It is with its help that you can make a hole in a stone wall or a depression in a concrete structure. Therefore, both the home craftsman and the builder should know how to work with a puncher.

Also, such a tool allows you to quickly and easily drill the required number of holes in ceramic tiles, brick, wood, metal. And additional nozzles will allow, for example, to drill the floor, compact the material, hammer in the rod and even tighten the screw.

Depending on the application and the availability of additional accessories, the rotary hammer can be used for a wide variety of construction operations. But how to do it correctly to prevent the tool from breaking down?

For what materials can the rotary hammer be used:

  1. Is it possible to tighten screws, self-tapping screws with a puncher? Whenever possible, many professional builders prefer to use a power tool that is capable of performing the functions of several types of equipment. The hammer drill is one of them. For quick and convenient screwing in screws or screws, special nozzles are used. Among them there are models with a limiter, which guarantee control of the "sinking" of fasteners.
  2. Is it possible to interfere with the solution with a perforator? It is possible, and quite effective at a low viscosity of the solution (for compositions of high viscosity, it is recommended to use a stirrer nozzle and work at minimum speed). Additional arguments in favor of this use can be that the speed of rotation of the tool shaft can be easily changed. In addition, according to the principle of its operation, the perforator differs little from the construction mixer.

3. Can a puncher drill wood? Using a puncher, you can get enough quality holes. To do this, you need to use the power tool in drill mode and use special drills. The drilling speed is determined depending on the material and hole diameter.

4. Can a puncher drill tiles? The main problem in working with ceramics is that they can crack if mishandled. That is why, when using a hammer drill, it is necessary first of all to turn off the percussion mode, and it is better to start drilling at low speeds with a gradual increase in speed.

Five. Can a puncher drill metal? Provided that a special drill is used, it is possible to create holes with this tool in almost any material. In most cases, they have a cylindrical shank and a spiral design. The material for their manufacture is high strength steel (often based on cobalt alloys). versatile in use will be drills equipped with carbide inserts on the cutting edge.

Preparing the punch for work

Pre-preparation of the tool is required in cases where it is assumed that during operation, replacement of bits will be performed. In this case, the following operations are carried out:

  1. Removing and cleaning the cartridge;
  2. Lubrication of its inner part;
  3. Installation of the cartridge with the lubricating ring shifted;
  4. Turning the cartridge for more reliable fixation;
  5. Blocking after releasing the ring.

All work in accordance with the operating instructions and safety precautions can be performed only on condition that the rotary hammer is disconnected from the mains. It is recommended to run the tool in idle mode before use. This is necessary to make sure that there is no extraneous noise, vibration while working with a drill or chisel.

Can the mortar be mixed with a conventional drill or perforator?

Grouting is an integral part of construction work. Mixing it in large quantities is quite difficult and also time-consuming and labor-intensive. A hammer drill or a powerful electric drill is well suited for this. You should not rush to rent, let alone buy a concrete mixer or a construction mixer. In most cases, this is not advisable at all.

Can I mix with any tool?

It is important to understand that the weaker the power tool, the harder it will work. If we are talking about using a drill, then it should be borne in mind that not every model is designed for this kind of load. For example, a 500 W device is not capable of fully mixing the building mixture. With intensive work, the drill motor will definitely fail. This tool can only stir the solution in very small volumes (about 10 liters) and for a short time. It is also important that it is not thick concrete, but putty, primer, or similar mixtures.

A completely different matter, this is an electric drill with a powerful 1300 W motor, better than 1500 W. A similar model may well cope with mixing mortar. However, you should still not overload the tool with increased intensity of work, and also try to knead too thick mass.

As for the application for punching, this is a more reasonable solution. This tool is designed for increased loads and is equipped with a powerful power unit. However, it is best to take frequent breaks when mixing concrete.

How to mix the solution?

Regardless of the choice of tool, the building mixture should be kneaded from the most liquid consistency to a thicker one. In other words, add cement and sand to the composition of one bag in order to achieve the required density in two, or better, three passes. If you try to make a very dense solution right away, it will be quite difficult and negatively affect the motor and the internal mechanism of the power tool.

  • Screw;
  • Cruciform;
  • Combined.

Screw mixers are used to obtain liquid mixtures, and cruciform mixers are used for thicker ones. Right-hand spiral cruciform nozzles work well with mortars that include gravel or crushed stone. The nozzle distributes the components evenly throughout the volume, preventing them from falling to the bottom. Combined nozzles are a versatile solution and can be used in mixing any building mixture.

To minimize the stress on the drill, it is best to opt for a mixer with the smallest possible working section. The wider the mixer blades, the more power is required to rotate them under the load of the solution. You can purchase a more impressive mixer for a perforator than for a drill. Because this tool can work under heavy load and develops a lot of power.

Basic tools for hand batching concrete

Concrete mixing, like every working process, begins with the preparation of materials – water, cement, sand. You also need a container – a large vessel to mix it all.

Let’s consider in detail the most important elements in the preparation of manual mixing of the material:

1. Capacity

If you can manually stir with a shovel directly on the ground or on a metal sheet, then the mixer needs dishes. The container for mixing concrete should be trough-shaped. The most comfortable. Metal bathtub, basin. It is also possible in the barrel if it is shallow. The dimensions of the trough depend directly on your need for the finished product. For small amounts of concrete, it is better to use small containers. If it is necessary to raise the finished solution to a height, use containers with special hooks for fastening the rope. To extend the service life of such vessels, it is worth following a few simple rules. The first of these, which must be performed, is the constant cleaning of the inner surface from concrete residues after each use.

2. Construction mixer

The preparation of small quantities of concrete involves the use of a construction mixer. Only this unit allows you to create a uniform mixture, which is then easy to distribute over the working surface. Mixer. Guarantee of high-quality concrete pouring. For mixing concrete, it is worth choosing a powerful device that can withstand the full force of the workload. The quality of the nozzle, its material and shape also play an important role. You choose it yourself, as there are cases when the whisk is included in the kit. For concrete, screw nozzles are most often used, which prevent air from entering the mixture. The hand-held construction mixer will easily and quickly cope with uniform mixing.

3. Additional tools

For transportation and further work with the ready-made solution, wheelbarrows, buckets and shovels are very often used. We carry with a wheelbarrow, we measure and carry with buckets. And shovels are used to collect ready-made concrete in containers for transportation and transfer. By the way, it is also convenient to use a shovel to scrape fresh solution from the walls of the basin or bath after work.

4. Materials

It is impossible to mix concrete correctly without quality materials. That is why, before the very procedure of work, not only a reliable drill mixer is selected, but also cement, sand, crushed stone and water that are good in their technological characteristics. The proportions for concrete can differ, which leads to the creation of different types of material in their properties. Optimal ratios for home construction:

  1. 1 part cement to 3 parts sand;
  2. Crushed stone – as much as sand and cement together – 4 parts;
  3. Water – 1 part.
  • Cement. Dry powder of gray color, which is capable of forming a plastic mass when mixed with a salt solution or water. This solution hardens and becomes like a stone. In the composition of cement, you can see the name of different substances, which led to the division of cement into types – alumina, slag, expanding, etc. The most popular type of cement in construction is cement PC (Portland cement). In turn, it is also divided into several types. The type of cement determines the quality of the concrete for which it was used to replace. As the most suitable one, I recommend Portland cement with its high and prevalent calcium silicate content. Grades with the designation M200, M300 – they harden normally and withstand loads and weight well.
  • Sand (as well as cement), it is better to choose dry and poured. Ideally, river, washed. The sand should have a grain size of 1.5 to 3 mm.
  • Crushed stone – small stones, come in different sizes. Fine crushed stone – 5 mm, coarse. 20 mm. For home mixes, it is good to take crushed stone with a diameter of 5-10 mm. If necessary, sand and crushed stone must be cleaned of foreign impurities.

Manual concrete mixing tricks

Making concrete with your own hands is a little time consuming, but, in principle, there is nothing complicated. Especially if you have certain skills, and also know the basic tricks of this process. I’ll try to highlight the main secrets:

  • Mixing time should not exceed 10-15 minutes.
  • The kneading point should be no more than 50 m from the place of installation.
  • Manual mixing with a mixer is best used for small amounts of concrete. Optimally 20-30 liters. This makes it easier to achieve uniformity.
  • You can also knead 50 liters, just make sure that the nozzle reaches the bottom of the container. Its standard length is about 60 cm, if not, lengthen it by purchasing a special device.
  • It is better to take crushed stone of two different fractions – small (5 mm) and larger (10 mm).
  • When manually mixing, it is better to mix the dry ingredients first, and only then add water. In a concrete mixer, just the opposite – first pour a little water.
  • At sub-zero temperatures, I do not recommend mixing and pouring concrete. The result is not predictable, because water can provoke freezing and cracking.
  • In cold weather, the water can be slightly warmed up – it should be warm, but not hot.

Manual concrete preparation process

How to prepare concrete with your own hands so that the mixture is of high quality? This question is of interest to many builders, because concrete can be mixed, and who will then be responsible for cracks and uneven coverage? Today, there are two ways to prepare concrete using a mixer. To prepare a small amount of concrete in the shortest possible time and get an excellent result, you can use either one or the other – of your choice.

1. The first method is the most common. First, dry components are mixed in the required proportions. The cement is carefully and evenly mixed with sand in proportions of 1 to 3. Gravel is added. Mix for 5 minutes. Then, in a uniformly mixed mixture, make a funnel (you can use a shovel). A measured amount of water is added to it. And they interfere again. This manipulation (water at the end) is carried out so that the water cannot raise the light cement to its surface, preventing uniform mixing. If you pour the cement itself with water, it will lead to lumps in the mixture, but who needs them? In terms of proportions, the best option for a mixer is:

  • 3 kilograms of cement
  • 9 kilograms of sand
  • 12 kilograms of rubble
  • 3 l of water

The total approximate amount of the mixture is 27 liters. Very suitable for a normal construction mixer.

2. Method two. It consists in pouring water first. And then, in the measured amount of water, according to the proportion of concrete preparation, cement, sand and crushed stone are poured. Then, using a drill, such a mixture is brought to a state of uniform consistency. I like the first method better, because the second can lead to lumps. But, in principle, with a good mixer and the right attachment, the mixture should be homogeneous. The advantage of this method is that less solution sticks to the walls of the container.


The ergonomics of a specialized construction mixer contribute to a comfortable work to the greatest extent. Most models are equipped with a double-ring handle. In powerful tools, a T-shaped handle pattern is used to reduce hand stress during operation – a wide bracket, at a right angle to which a handle with a trigger for adjusting the spindle speed is located.

This arrangement makes it possible to hold and move the mixer with a torque of up to 200 Nm without any problems. To improve the quality of the mixed mortars and to facilitate the work, some models of professional construction mixers are double-spindle and have two nozzles that rotate in opposite directions, mutually compensating for the high torque.

For tools with a motor of more than 1 kW, for the rational use of its power, a two-speed gearbox is used, the gear ratio of which provides a mode of operation with high torque and low rpm in the first gear and a decrease in torque with a simultaneous increase in speed when switching to the next gear.

The first gear is intended for mixing heavy viscous and viscous mixtures – cement and gypsum mortars, mixtures for screeds, mastics, sealants, etc.

For stirring light mixtures with a liquid consistency with a low viscosity – paints, varnishes, adhesives, spray solutions, etc. The mixer operating mode is used with a high rotation frequency of the nozzle and a lower torque.

When working in a cold season in an unheated room, you must also take into account the fact that many building mixtures at low temperatures increase the viscosity.

For comfortable work, you should choose drill mixers and specialized construction mixers equipped with a speed stabilization system and a starting current limiting system. Since when removing the nozzle from the mixture, the working load on the tool disappears and without the speed stabilization system, the rotation speed of the nozzle will increase sharply, which leads to splashing around the mixed material. The inrush current limitation or soft start is designed to prevent the spray of light solutions or rotation of the container with a heavy viscous mixture when the tip is immersed.


Considering the above, a reasonable way out, if it is necessary to stir liquid or viscous building mixtures in a volume of no more than a bucket (about 15 liters), would be to purchase a drill-mixer.

In contrast to the standard version, the drill mixer is equipped with a needle bearing that can withstand significant loads, a more durable gearbox in a metal housing, the reduction gear ratio of which allows working at low speeds.

The latter, in combination with a more powerful motor, provides the tool with a high torque, which is important for mixing thick and viscous solutions. At the same time, the function of drilling holes is also retained by the tool.

In turn, their disadvantage, in comparison with a standard drill, is the greater weight due to the design features (usually more than 3 kg), which affects the weight when drilling. Models weighing less than 3 kg, are designed for more gentle conditions – mixing light flowing solutions.

The cost of drill-mixers depends on the operating parameters and varies in a wide range – from 40 to 900 For long-term mixing of large volumes of mortars of all types, a special power tool has been created – a manual construction mixer. The cost of such a tool ranges from 150 to 1000 and more.

When the nozzles rotate, a moment of forces acts on the mixer body, twisting the instrument body in the opposite direction, just as the large main rotor of a helicopter not only lifts it up, but also rotates the fuselage around its axis. And if in a helicopter to compensate for the torque of the main rotor, as a rule, a tail rotor rotating in a vertical plane is used, then in a hand mixer for this purpose the hands of the person holding it are used.

Since the drill mixer is a multifunctional tool, this does not allow to fully adapt its shape, both for drilling operations and for mixing various solutions. The main function of such a drill is considered to be drilling holes, which basically determines its shape. An optional set of removable handles is provided to aid in holding the tool when mixing with a torque of 20 – 70 Nm.


The industry of finishing materials and special building solutions is constantly evolving, creating an ever wider range of materials to improve comfort in our homes and work spaces. Modern multicomponent water-soluble materials for decoration, adhesives, insulating materials are initially sold in the form of powder or granules and for further use they must not only be dissolved in water, but thoroughly mixed, having achieved a high degree of homogeneity.

When using such improvised means as a brush, a stick or a curved thick wire for stirring, it is almost impossible to achieve a homogeneous suspension – there are always lumps or small clusters of stuck together particles, which affects the quality with further application of the solution.

And if it is necessary to prepare a cement mortar, then in the “old-fashioned” way without using a classic drum electric mixer (popularly called concrete mixer AL-KO), you will first have to mix concrete with cement dry with a shovel, and then mix again after adding water. This process requires a lot of effort. And if you still need to add crushed stone to the solution

However, even having realized that it is quite problematic to prepare a high-quality mixture by hand, we are still trying to save money and find a way out with the help of available tools, in particular, expanding the range of functions of various tools at our discretion. Therefore, perforators and drills are used for the preparation of mortars.

It is quite a popular misconception that if the rotary hammer has a rotation mode and a sufficiently powerful engine, then they can easily interfere with building mixtures during repair work. However, the perforator was originally designed for the load of the nozzles along the longitudinal axis, and when the solutions are mixed, significant radial loads act on the tooling.

Therefore, it will be possible to knead a small amount of solution one time, as a rule, without any particular problems, except for welding the SDS shank onto the mixer nozzle. But when mixing the volume of various mixtures required for repair, especially viscous solutions, such use of a perforator leads to failure of the SDS chuck clamping mechanism or damage to the barrel, while the cost of repair can reach a third of the cost of the tool.

In this regard, it is often advised to replace the hammer drill with a cheaper drill. However, a standard drill is also structurally not suitable for mixing mortars and paints.

It will, of course, mix up, but with such exploitation there are a number of objective factors that cause its early "death". While hammering, the drill operates at low speed, which causes a strong heating of the motor windings, thereby shortening the tool’s life. Radial loads on the mixer nozzle “swing” the barrel with the cartridge “killing” the bearing and gears of the reducer. An additional negative effect is also exerted by splashes of the stirred liquid entering the drill.
