How to make concrete for wiring and pipes with your own hands using a hammer drill or wall cutter? Step-by-step instructions + Video

A wall chaser is a tool for creating recesses in construction objects (walls, ceilings, floors) and materials (tiles, bricks, blocks). When working with a wall chaser, dust inevitably arises, which causes inconvenience even on the street, not to mention situations when you have to cut indoors. A vacuum cleaner will help to cope with this problem, but not an ordinary household one, which will simply break down from such loads, but a special, industrial one.

The best manufacturers of vacuum cleaners for wall chasers

A leader has long been identified in the market of washing and cleaning industrial tools. This is a German company KARCHER

(Kärcher).
It also produces special vacuum cleaners, and in a wide range. These are powerful, high-quality and reliable units designed for the highest loads. Bosch
,
Makita
and
Bort
are not far behind the leader . They also have the highest quality, and in terms of the variety of models they are all ahead of Karcher.

Moving to a more budget segment, it makes sense to pay attention to Russian manufacturers Caliber

,
Zubr
and
Soyuz
. It is worth noting here that they are only slightly inferior in quality to the market leaders, but significantly beat them in prices. Vacuum cleaners of these brands are cheaper initially, as are their repairs in case of breakdown.

Kinds

Furrow cutters are classified according to the type of cut:

• Straight (saw blades are located at 90* relative to the plane being processed).

• Angular (the angle of inclination of the discs is adjustable).

Due to the extremely narrow specialization and high price, corner wall chasers are not in demand on the market. Usually, if a corner groove needs to be cut at a site, craftsmen rent such a tool.

How to choose a vacuum cleaner for a wall chaser

The main criterion for choosing a suction device is its maximum compatibility with the wall chaser itself. For example, if you have a very powerful and fast wall chaser. Then the vacuum cleaner may simply not have time to suck up the resulting dust. There is no ideal formula, but experience shows that a ratio of 1:2 is quite sufficient. That is, if your wall chaser has a power of 2 kilowatts, then the vacuum cleaner should be no weaker than 1. However, almost all modern models have such characteristics. Finding a vacuum cleaner with less than a kilowatt of power is very difficult.

Air consumption, which is relevant when choosing a conventional vacuum cleaner, does not matter much here. The hose is connected directly to the wall chaser, that is, the capture of generated dust is already maximum. It is much more important to look at the convenience of a particular model:

• what container is used;
• are there any protective functions;
• how automatic cleaning works;
• How maneuverable and easy to transport the vacuum cleaner is.

And, of course, an important factor is the overall quality of the unit. There are a lot of manufacturers on the market, some well-known and some not so well-known. They all “guarantee” high quality and reliability, but in reality this is not always the case. To make the selection process easier for you, and without personal experience it is impossible to determine which model is better and which is worse, we have selected the most popular and sought-after models that have collected the largest number of reviews from real users.

What it is?

Also known as a furrower, a wall chaser is an extremely practical power tool in the conditions described above. Its main function is to create grooves (grooves) of appropriate sizes in walls made of brick or concrete, where wires and pipes are hidden during the repair process. Working with it may not be the easiest due to various circumstances, and therefore when choosing, it is important to take into account a lot, from its design features (dimensions and ergonomics), to basic and additional features such as power or dust collection system.

Its operating principle is not much different from the same angle grinder, which, by the way, can become a replacement for a wall chaser in some cases. True, the latter option carries the risk that you risk spending much more time on the process of creating a furrow, and there is a high probability that it may not turn out the smoothest. Therefore, from the point of view of saving such important resources in repair and construction work as effort and time, it is recommended to use exclusively a furrow maker. In addition, it will provide much more opportunities, such as adjusting the groove parameters, which we will definitely talk about later.

• Country: China
• Power (W): 1300
• Vacuum (mbar): 190
• Air consumption (l/s): 30
• Dust capacity (l): 15
• Hose diameter (mm): 32

If you rarely use a wall chaser and the construction vacuum cleaner will be primarily used for another purpose, this model is worth paying attention to. This is an inexpensive Chinese unit with high performance, but the most ill-conceived system. Its power is 1500 watts and the vacuum is 190 mbar. In practice, this allows you to collect heavy suspended matter, but not for long, since the volume of the dust collector is only 15 liters. Moreover, it is fabric, so it is better to avoid collecting metal shavings. But here is the longest hose: 4 meters is the best indicator, which even Bosch and Karcher did not achieve.

Advantages and disadvantages

• Extra long hose
• Compact dimensions

• Very small dust container
• Fabric garbage bags
• Not the highest reliability

A vacuum cleaner with a high power rating, suitable for complex cleaning jobs and heavy dust suction. A vacuum of 170 mbar allows you to cope with granite chips and metal shavings, although in the annotation the manufacturer indicates exclusively carpentry use of the tool. But in the reviews, users write a lot about their experience with the wall chaser, and it is quite successful. But the manufacturer clearly did not succeed with ergonomics. There is no container for storing attachments or a rotating moving platform. Ideally, if the vacuum cleaner will be used as a stationary one. But it is inexpensive and has a long power cable, as well as a 2-kilowatt household outlet.

Advantages and disadvantages

• Inexpensive vacuum cleaner
• Metal body

• No moving wheelbase
• Poorly thought out ergonomics
• Short hose

Reinforced body Vacuum cleaner with an all-metal body and a plastic base. The model is not afraid of accidental impacts and falls, which is very important in production or construction sites.

• Characteristics

  Average price: 7,500 rub.

• Country: Germany (manufactured in China)
• Power (W): 1400
• Vacuum (mbar): 210
• Air consumption (l/s): 42
• Dust container capacity (l): 25
• Hose diameter (mm): 32

A construction vacuum cleaner must not only be powerful, but also durable to withstand accidental impacts and falls. This model fully meets these requirements. Unlike other Bort models, this one has a completely metal body, as does the dust collection container. A wide platform with swivel wheels will prevent the unit from simply falling. BSS-1425-PowerPlus is an inexpensive but powerful construction vacuum cleaner that produces 1400 watts and 210 mBar of vacuum. Air consumption – 42 liters per second. The indicators are not record-breaking, but high enough to carry out the most complex work. In addition, a semi-automatic filter cleaning system has been installed, which greatly simplifies the work.

Advantages and disadvantages

• Self-cleaning system available
• Rugged housing
• Wide wheelbase

• Heavy model
• Inconveniently located socket

Basic Rules

Chasing walls for wiring refers to the rough work of major repairs, therefore, such work must be subject to certain rules:

1. You can only dab vertically.
   All wiring is carried out along the ceiling, so even if there are several sockets or switches on one wall, a separate outlet is connected to each of them. Neither horizontal nor diagonal grooves are allowed. It is important to know. If you follow this rule, you will always know in which place on the wall you cannot drill a hole so as not to get into the wire.
2. The cable or wire in the wall is laid only in a pipe or corrugated pipe; the width of the groove must ensure installation of pipe fasteners inside, and the depth is 10 mm greater than the diameter of the tube.
   This will ensure reliable fixation of the plaster layer on top. Laying the wire inside a PVC or corrugated pipe provides the possibility of replacing the cable in the future without dismantling the walls. It is important to know. The minimum Ø of a corrugated pipe is 16 mm, therefore the minimum depth of the groove should be 26 mm.
3. If there is a need for several pipes, the groove can become wider, but not deeper.
4. Coordination with the management company for gating walls for wiring is required only if work is carried out in a panel house on a load-bearing wall without plaster. If a layer of plaster allows you to make a groove in it without touching the slab itself, approval is not necessary.

Before us is a Russian-made vacuum cleaner that produces 1800 watts of power. With this indicator, it can easily cope with even the heaviest dust, for example, granite or marble. This is what this model is designed for. The vacuum is 180 mbar, which is not a record, as is the air consumption, but these parameters are fully compensated by the power of the unit. Of course, the vacuum cleaner will consume more energy, but nothing can be done about it. Also, the size of the dust collector of 30 liters and the container design allow it to be classified as heavy tools. No bags constantly tearing and scattering the collected garbage. This is a full-fledged construction vacuum cleaner without a hint of elegance in appearance.

Best value for money Construction vacuum cleaner from a top manufacturer at a very attractive price. A high-quality model with a high level of reliability.

• Characteristics

  Average price: 8,500 rub.

• Country: Germany
• Power (W): 1200
• Vacuum (mbar): 200
• Air consumption (l/s): 60
• Dust container capacity (l): 20

We have before us a unique case when a manufacturer underestimates the parameters of its product, rather than overestimating them. The annotation of the vacuum cleaner states that its class corresponds to light, that is, it is designed to collect exclusively light dust and mist. At the same time, the technical parameters tell us that it can easily cope even with granite chips and metal shavings. For 1.2 kilowatts of power there is 200 mBar of vacuum and 60 liters of air consumption. These are quite high values, which are not found in all models recommended for heavy work. Well, Metabo decided to play it safe and left a serious reserve of power. Given the brand's reputation, this deserves special respect.

Advantages and disadvantages

• Large power reserve
• High technical parameters
• Long cable
• A light weight

• Short hose
• Very thin fabric bags

Criterias of choice

When purchasing a tool, you should pay attention to such parameters as:

• Power . The most important factor that determines the performance of a device. Varies from 900 W to 3 kW. The main rule is that the power must correspond to the diameter of the disk and the work performed. It is advisable that the device have a power reserve - this will protect the motor from overheating.
• Disc diameter . Determines the maximum depth of the groove to be made.
• Disk rotation speed . It determines how high quality the cut will be.
• Adjusting the distance between discs. For laying wires, a groove 1-2 cm wide is enough. If the task is to install a pipe into the wall, this figure should be much larger. Therefore, the adjustment range must be selected according to the purpose of the work.
• Weight. The lighter the device, the less your hand gets tired (it is especially important to take into account the weight when working on ceilings). At the same time, it is possible to reduce the weight of the tool only simultaneously with a decrease in power.
• Noise level. The sound of discs cutting concrete is usually very loud. It is advisable that the overall volume is not increased too much by the noise of the electric motor. You can check this indicator by starting the engine at idle speed.
• Vibration. There is no information about this characteristic in the instructions. The degree of vibration can only be assessed experimentally or based on feedback from tool owners.
• Auxiliary functionality: smooth start;
• protection against overload, jamming, accidental activation;
• automatic rotation speed control;
• vibration damping system;
• maintaining cut depth.

• Hose diameter (mm): 35

Bosch is one of the leaders in the tool market, and it constantly maintains its reputation. Here is a vacuum cleaner that customers called the most reliable and unpretentious. It works without interruption and even requires much less frequent filter changes. However, this is easy to explain. The Bosch vacuum cleaner used a special technology with which the tool cleans the filters itself, and you only need to change them from time to time. In terms of power indicators, everything is also in order. At 200 mbar of rarefaction there is almost 1.3 kilowatts. Despite the low air consumption of 35 liters, the vacuum cleaner can handle even heavy dust. And the presence of a humidifier significantly expands the scope of application of the tool.

Advantages and disadvantages

• Self-cleaning filters
• Compact form factor
• Long hose and wires
• High reliability

• Not the most attractive price tag
• No adapter for changing hose diameter

Safety

When working with a power tool, it is also useful to have certain protective mechanisms. Fortunately, most wall chasers have them. Among the most common is protection against disk jamming. From a safety point of view, this option should be present on the model you are looking for, especially if it needs to be powerful. You never know what could go wrong, and if the disk jams during the gating process, models with this protection either turn off completely or go into idle mode.

There is also a more banal, but no less practical in terms of safety, protection against accidental activation. Although, in terms of safety and the tool itself, it is important to have protection against overheating, because the furrower will not have to work in the easiest conditions, constantly experiencing a certain load. The presence of such protection will allow you to avoid troubles and very expensive repairs, allowing the wall chaser to serve you reliably and for a long time.

Best price The cheapest construction vacuum cleaner, costing about 15% less than the closest competitor with similar technical characteristics.

• Characteristics

  Average price: 5,500 rub.

• Country: Germany (manufactured in China)
• Power (W): 1300
• Vacuum (mbar): 160
• Air consumption (l/s): 29
• Dust container capacity (l): 25
• Hose diameter (mm): 32

Low price is the first thing that catches your eye when looking at this unit. But if you decide to choose it, keep in mind that the technical indicators here are quite low. The vacuum cleaner has 1300 watts of power, which is very impressive, but it only has 160 mbar of vacuum and 29 liters of air consumption. Simply put, if you use a vacuum cleaner on a wall chaser, you can only work with light materials. The tool will easily collect gypsum and aerated concrete dust, but it will not be able to cope with heavier suspensions. If this suits you, then you can save a lot of money. The BSS-1325 is an inexpensive wet/dry vacuum cleaner that is definitely worth a look.

Advantages and disadvantages

• Large dust bag
• Inexpensive option
• High motor power

• Low vacuum and air consumption
• Fabric dust bag

Rules of use and care

By following these simple rules, you will keep your assistant in working condition for a long time, and also protect your health:

1. Only plug and unplug the power cord when the instrument is unplugged.
2. Be sure to wear safety shoes, clothing and eyewear. It is advisable to protect the respiratory system as well. The dust generated during work is extremely harmful to health.
3. When changing the width, carefully secure the spacer washers.
4. When gating, hold the wall chaser with both hands and at a safe distance from you.
5. After 2-3 minutes of grooving, remove the tool from the groove and let the engine run for 15 seconds without load. This will cool it down.
6. Don't squeeze everything out of the tool. Stick to a medium load.
7. Do not work in damp areas or on wet surfaces.
8. After work, wipe the wall chaser with a slightly damp cloth, then dry it, put it in a briefcase or box and store it in a dry, warm place out of reach of children.

Expert opinion

Levin Dmitry Konstantinovich

You should change the original disks of the instrument carefully. You should buy blades of the same brand as the tool, otherwise imbalance along the spindle may occur with subsequent failure of the device.
