Any repair requires certain costs. With modern repair technologies, special materials and equipment are required. To make grooves in concrete for electrical wiring, you need a wall chaser. The editors of the site "bestx.htgetrid.com/en/" have prepared for your attention an overview of the best wall chasers worth from 5 400 rubles. up to 41,180 rubles.

How the device works
A furrow cutter is a power tool with a built-in spindle. Cutting abrasive or diamond discs (2 pcs.) Are attached to it at a certain distance between themselves, which can be adjusted using rings with different thicknesses.
The device has guides with rollers that allow you to adjust the required furrow depth. The tool leaves behind two parallel grooves of the required dimensions. The remnants of the concrete or brick formed between them are knocked out with a jackhammer or perforator. On top of the discs there is a casing with a hole where dust collects.
Small-sized chasing cutters are used for laying electrical wires. They have good performance and high productivity. A groove is made up to 3 mm wide and deep.
More powerful and bulky "furrowers" are suitable for laying pipes with a diameter of up to 50 mm. To obtain grooves of large sizes of tools, two or more cuts are performed.
When working with a wall chaser, you must use an industrial vacuum cleaner. To connect it, all types of tools are equipped with a branch pipe.
"Furrow makers" with two discs are more powerful than with one disc (less work load).
Types of wall chasers
The power tool is designed to facilitate work during the laying of electrical wires, plumbing pipes and wiring the heating system in small and large rooms. New technologies allow to give the interior an aesthetic appearance, providing protection for pipes and cables from external influences.
Wall chasers are:
- "Manual" - it is convenient to work with not very hard material (wood concrete, foam concrete and aerated concrete);
- "Electric" - copes well with concrete, stone and brick;
- "Straight" - when working with hard surfaces (the location of the discs at an angle of 90 degrees.);
- "Corner" - work with corners (the distance between the surface and the working discs is regulated);
- "Wall chaser-furrow cutter" is a combined version of the wall chaser and an angle grinder.
The listed types of tools refer to standard types of wall chasers. There are also other devices, the operation of which depends on the type of material of the working surface.
The circular is suitable for working on soft material (wood). This option is good for making wide strobes. Concrete and brick can be processed with a grinder. It is used for cutting in two stages. The asphalt can be repaired with a gasoline-powered floor saw. Metal requires the use of a gas cutter with a special disc.
A furrower from a grinder: disadvantages
Many repair specialists do without special equipment and use a grinder when working with hard surfaces, on which they independently select a nozzle for concrete. This avoids high costs, since a professional tool is quite expensive.
This has its drawbacks:
- the device is impractical when cutting a large number of grooves;
- too much dust is formed, which hangs in the air for a long time and hinders further work;
- there is a loss of time during general repairs;
- the edges of the strobes and their depth are not the same size;
- there is a risk of injury: a piece of material may fall off when the core is removed between the strobes;
- the grinder can quickly fail.
To improve the quality of work performed by a "homemade" furrower, it is necessary to solve such issues as:
- dust removal;
- installation of 2 disks instead of one;
- the presence of a protective casing;
- provide adjustment of the cutting depth.
Installing parts
The second disc must be installed strictly at 90 degrees to the cutting plane. It is necessary to ensure the safety of the structure. Slight misalignment at high speeds can lead to seizure of the tool (gearbox or motor).
Installing a protective cover allows you to cover the part of the circle that does not sink into the wall. The casing, which performs a protective and dust-collecting function, is a flattened cylinder with a cut off the side. It is equipped with a socket for connecting a vacuum cleaner hose. The cylinder must be high enough to accommodate 2 discs at a specified distance from each other. This requires semicircular plates (2 pcs.) Of metal and a strip of steel to hold them together. The strip must be bent and welded to the rounded parts of the plates. The base for the casing is ready.
The presence of a protective cover is very important: it also serves as a guiding function. The wall chaser can be easily moved along the wall if the wheels are attached to it.
Important points
The discs will be adjusted by attaching two corners (the lower part of the "letter", L or T - shaped) to the upper surface of the protection. It is necessary to ensure free lowering and lifting of the lower edge of the guard.
Fixation is carried out with a bolted connection. Part of the "letter" on top for stability. It is to it that the wheels are attached to easily and smoothly move the wall chaser along the wall.
The side parts must be welded to the base of the guide (casing) so that dust is retained and does not come out of the protective case.
To install the second shaft, you need to make a new disk. You can turn a nut to clamp the first circle and hold the second, since the factory shaft does not allow you to fix two discs at once.
Expert advice
The nut is machined easier than the shaft itself, which is connected to the gearbox. It must be made directly with the sleeve. You need to put on discs like this:
- first we install the first disc on the grinder shaft;
- then we put the sleeve, and on it the second disk;
- the nut goes through the upper shaft and sleeve;
- then we tighten the block: we clamp the second shaft with the sleeve so that the first disc is pressed.
If the entire device is out of order, do not disassemble it. We buy a new one and rearrange the nut on it.
DIY wall chaser: features of work
The device of the grinder, its power is designed to carry out work with metal (stripping and cutting). In this case, the force is created thanks to the bevel gear.
The increased load on the grinder disables the mechanism, since the other disc is not intended to be installed on the grinder and the force is applied at a completely different angle.
Following simple rules will allow you to keep the tool in working order and perform simple construction tasks:
- estimate the amount of work: how much faster will work with two disks;
- the tool should not overheat, you need to work intermittently;
- be sure to use a protective cover with adjustable cutting depth;
- consider the option of carrying out work with one shaft, which will increase the life of the grinder.
You can use a high-quality self-made chasing cutter for repairs.This will save material resources. At the same time, there remains the risk of failure of the grinder.
With a large amount of work that has to be done quite often (professional activity), it is better to purchase a professional factory wall chaser.

Choosing a worthy tool: selection criteria and mistakes
A high-quality tool allows you to work quickly and with high efficiency of the final result. Before buying a tool, you need to take into account some important points that will help you avoid mistakes and not be disappointed in the chosen model of the wall chaser.
Before buying, you should:
- Study the rating of the most popular and best models of wall chasers on the market.
- Consider the cost of the product: sometimes a product at an average price can be better in quality than an expensive branded product.
- Pay attention to the quality of the material of the tool and its accessories, (+ date of manufacture);
- An important factor when choosing a model of a wall chaser is the storage location of the goods (it must be stored in dry rooms).
- Turn to the characteristics of the tool: weight, dimensions, engine power, description of the cut processing, etc.
- Consumer reviews are important.
The ability of the chaser to meet the permissible furrow width and depth is the most important criterion when choosing a repair tool. The permissible groove width for laying a single electric cable in the corrugation will be 20 mm, and for pipes - 45-60 mm. Depending on the parameters of the work performed and the target orientation, you need to choose the appropriate model. The cutting depth of 60 - 65 mm can be considered the most worthy.
