Groove cutting — an essential element of quality repairs, therefore without the best wall chaser obviously not possible. What kind of instrument is this? What can you do with it in the house? What parameters should you use to choose a device with a fancy name? Don't worry — We will answer all questions in this article.

What is a wall chaser and which one is better?

Wall cutter is a device for cutting grooves (or grooves, grooves) in brickwork, stone, concrete and other strong materials on the basis of which walls are built.

Unlike the same grinder, this device has two parallel diamond-coated cutting discs. The discs do not stand in one place - they can be adjusted, thereby increasing or decreasing the width and depth of the furrow. It is precisely because of this that it is worth taking a furrow cutter instead of an angle grinder - the quality of the grooves outweighs.

Also, the choice of wall chaser goes in favor of less dust during operation. It is used in installation and construction: when laying pipes, wiring, heating and other communication systems.

The best wall chaser for concrete is one of the devices to which it is impossible to attach a standard classification into household and professional devices. For household or semi-professional tasks, choose a compact and lightweight device - you won’t go wrong.

Which wall chaser is better to buy?

As with any other tool, we will pay attention to some main points:

Equipment power and weight. Its performance and speed directly depend on this. You can find wall chasers rated at 1 kW or more. Light models consume no more than 1.5 kW; for huge models the value varies between 2000-2500 W. Such machines do not have the same speed as light ones, but thanks to the torque they create furrows in the densest materials without any problems. Important: in situations where you need to work on weight (for example, drilling a ceiling), volumetric models will cause discomfort - choose the device wisely!

Revolutions. The higher the first indicator, the higher the speed. The efficiency of the wall chaser depends on the speed. Choose a device with performance from 5 to 11 thousand rpm. For particularly hard materials, it is worth buying a more powerful furrow cutter.

Diameter of the working part. We're talking about saw blades. The ability of the wall chaser to make deep grooves depends on this indicator (on average, the indicators range from 115 to 230 mm).

Additional features of the best wall chaser:

• Smooth start - evenly accelerates the engine, extending its service life. The discs accelerate evenly and do the job, transmitting torque from the engine and not loading it too much.
• Overload protection - will allow you to automatically stop the tool in case of uncharacteristic behavior of the wall chaser.
• Stabilization of revolutions - fixation of speeds at which it is convenient for the master to work. The system allows you to configure the device so as to produce high-quality furrows without physical effort.
• Dust removal is a special option that helps get rid of excess dust during work. Since you will be cutting stone or concrete, there will be a lot of it!

What a wall chaser can and should be equipped with

Additional handle - helps reduce hand strain and reduce vibration when cutting. This is especially important in massive devices, where everything depends on the physical characteristics of the master.

Anti-vibration system - a set of shock absorbers that reduce the load on both the hands and the motor.

Unexpected Start Lock - A switch that “prevents” the tool from being started accidentally.

Speed ​​control - button for setting the speed. Useful for sawing materials of different densities (concrete, brick, silicate, etc.).

Protecting the motor from debris - in addition to dust removal, some wall chasers have parts impregnated with resin. That is, all the dust settles on such components and does not get into the functional part of the device.

Fuse - allows you to protect the motor from possible damage if the device encounters particularly dense material or a splinter goes straight to the gearbox.

Suitcase - it is important not only to work comfortably, but also to have a place where all accessories will be stored along with the equipment.

A high-quality “Japanese” opens our rating of wall chasers. Has a motor power of 1800 W and an automatic switch. To adjust the width of the furrow there are 3 switching rings at once.

It has a durable metal housing that protects the gearbox from dust and building materials.

For convenience, the manufacturer packed the cutter in a transport case, and the P-shaped handle ensures comfortable operation.

Groove width ranges from 7 to 45 mm; depth can be adjusted up to 45 mm. The device is equipped with 150 mm discs. Operating speed - 7800 rpm.To stabilize the system, there is a smooth release button.

Einhell TH-MA 1300

Budget Chinese furrow cutter with good characteristics. Device power - 1320 W; discs with a diameter of 125 mm are installed. Cutting is performed at speeds of up to 5 thousand revolutions per minute. The package includes an elegant suitcase and two saw blades.

The furrows are adjusted in keyless mode. For user convenience, the handles are covered with rubberized material, the shutter button is located in a convenient location for the hand.

Bosch GNF 65 A

The company stands out for its powerful construction tools - this is one of them. 2.4 kW allows you to work with discs as much as 230 mm at 5000 rpm. The device provides ample opportunities for work: you can cut grooves up to 65 mm deep. The groove width is adjustable from 3 to 40 mm.

The peculiarity of the device is that it copes well with rough materials and does not slow down when it encounters a surface of higher density. The manufacturer added to the kit a durable storage case, a second handle for the wall chaser and 10 washers for maximum customization of the device for any situation.
