- When low-cost discs are used, jamming protection is constantly activated, and the original ones are not cheap.
Output. The tool is perfect, due to the work with disks with a diameter of 150 mm and a maximum gating width of 45 mm, for laying a thick power cable throughout the apartment to the junction boxes. It is used for professional activities with everyday use and at large facilities due to its long life.
Einhell TH-MA 1300
Inexpensive chipper from a German brand, assembled in China. The power of the tool is 1320 watts, and it supports two discs with a diameter of 125 mm. Strobing is particularly fast due to the rotation of the spindle at a speed of 5000 rpm.
+ Pros Einhell TH-MA 1300
- There are already two disks in the kit for work - you do not need to buy anything else.
- Comes in a beautiful case, convenient for transportation.

Output. Budget chipper, well suited for self-repair in an apartment or semi-professional activity. Its advantage is the compact size of 385x220x265 mm. With this tool, it is especially convenient to bring cuts to the ceiling and ditch the walls horizontally.
Bosch GNF 65 A
One of the most powerful chippers from a German company. 2.4 kW allow you to accelerate huge disks with a diameter of 230 mm to a speed of 5000 rpm. The equipment is capable of cutting a groove 65 mm deep.
+ Pros of Bosch GNF 65 A
- Four-point support roller system.
- Adjustment of groove width from 3 to 40 mm.
- Does not slow down when colliding with strong concrete or stone.
- It is completed with a practical and strong suitcase.
- It starts without jerks due to the limited supply voltage at the beginning.
- A set of 10 washers for various modeling installation of cutting discs.
- The second handle is inserted on either side of the housing.
- The long nozzle to the vacuum cleaner does not require adapters.
- Adjustment of a protective disk without attraction of the additional tool.
- Silicate brick cuts through like oil.
- Long wire.
- Cons Bosch GNF 65 A
- Very heavy chipper (8.4 kg) - it is difficult to hold with both hands for a long time when working even on a horizontal plane, not to mention the vertical wall.
- Constantly pulls to the left side - if you work without marking, it is easy to deviate from the course and not notice it.
- After starting, it gains maximum speed and is not adjustable.
- There are small gaps in the casing through which dust flies out.
- One of the most expensive models.
- There are no marks on the case for alignment and control of the cut line.
- The pipe sticks out uncomfortably.
Output. This model is included in the TOP chippers deservedly, because it leads in power, which is 2400 watts. The tool is best for making deep channels for communication in an apartment or house.
The best chippers with 3 and 5 working disks
The presence of three to five discs on one shaft allows you to immediately cut through the furrow, as a result of which the remaining material either falls out of the strobe on its own, or by applying small efforts. This greatly speeds up the work and simplifies the process of bringing the channels to the finished state.
But the cut is slower because they have to cut a large area at a time. It is a professional tool for builders and repair companies to lay electrical and plumbing communications in large buildings.

Metabo MFE 40
German wall chaser assembled at home. It is endowed with a power of 1900 W and a C-shaped second handle, which facilitates holding in various spatial positions. It is sold with one disc, but the manufacturer on its official website informs that the tool can work with three cutting elements.
+ Pros of Metabo MFE 40
- The support roller system contains four pivot points for better stability during strobing.
- There is a limitation of starting currents for a gradual start of rotation - there is no jerk at all.
- Creates grooves with a width of 9 to 35 mm and a depth of up to 40 mm.
- Spindle speed 5000 rpm.
- It is assembled directly in Germany.
- Suitable for Bosch vacuum cleaners without any adapters.
- The depth of cut is conveniently adjusted with the handle on the left side.
- Cuts everything from concrete to silicate bricks.
- Electronics maintains constant speed regardless of the density of the material.
- There is protection against restart.
- Cons Metabo MFE 40
- The cost is high.
- It is completed with only one disk, and the second and third need to be bought independently.
- The speed is not adjustable.
- Hands weighing 4.6 kg quickly get tired.
- A large case with a length of 474 mm is inconvenient to rearrange and transport.
- The gearbox lets dust in - it needs periodic cleaning and lubrication.
Output. This is a good shtroborez with three disks for quick wiring throughout the apartment, wiring channels to outlets, chandeliers. Power 1900 W is enough for cutting grooves in the walls of any materials. Maintaining constant speed will not lead to a drawdown in rotation when working with reinforced concrete.
MESSER T1455
Russian shtroborez going to Taiwan. It is equipped with a power of 2500 W and is able to spin the spindle to a speed of 8500 rpm. It is completed with a strong reinforced hose for a dust removal system.
+ Pros of MESSER T1455
- Reasonable price, much lower than famous brands, but the tool belongs to the category of professional.
- Comfortable rubber grip with ergonomic shape.
- Four rollers for better platform stability.
- Change the depth of gating with a screw on the right side of the housing.
- The rotation of the five discs at the same time completely selects the material between the borders of the strobe.
- You can install discs with a diameter of 125-150 mm.
- Cutting in width from 2 to 38 mm with a depth of up to 42 mm.
- There is a system for supplying water to the cutting zone to cool the discs and clean them.
- Cons MESSER T1455
- In addition to the chamfer and the hose, little will fit in the case.
- The speed of the discs is not regulated.
- Twitches at startup.
- Weight 8.5 kg - hands get tired after 5 minutes and need frequent breaks.
- Turnovers “float” under strong pressure and in a hurry - you have to drive off to the sawn section more often with reciprocating movements.
- Only good wheels are needed.
- The water supply system helps and harms at the same time - the liquid, colliding with dust, turns into slurry and interferes.
- Dust extraction hose as tight as from a fire hydrant.
Output. This is a good replacement for well-known brands. The shtroborez is useful for electricians who have priority in the execution of tasks. The presence of five disks allows you to immediately select the entire middle of the strobe and proceed to laying the cable.
The best shtrobrez-furrower
Shtroborez-furrow cutter is used when you need to quickly cut through the groove for laying a thin wire. The presence of one cutting element speeds up the process, but a thick cable cannot be inserted into the groove. In this case, you will need to perform a second slot, which will take twice as much time, and its evenness will turn out to be far from ideal.
Makita 4112HS
The furrower is assembled in Japan and the manufacturer endowed it with a capacity of 2400 watts. Designed to work with very large disks with a diameter of 305 mm.
+ Pros of Makita 4112HS
- It starts smoothly and is gradually gaining momentum.
- It is completed with a convenient suitcase and a wrench for untwisting of a shaft.
- Fast disk rotation at a speed of 5000 rpm.
- One of the largest depths of cut is 100 mm (they can even cut a small window in a brick partition).
- The wide start key is convenient for holding with all your fingers, and not just one that quickly gets tired.
- Double insulated insulation.
- Cons Makita 4112HS
- Weight over 10 kg greatly tires your hands.
- It does not support constant revolutions - the rotation speed depends on the density of the material.
- Another scheme of work (without rolling on the support rollers), but by the method of immersion of the saw blade, is therefore much slower than conventional chipper cutters.
Output. This is a good shtroborez-furrower for laying low-current systems (telephone line, Internet, antenna cable, alarm). One disk will make a thin groove for the establishment of a wire of small cross section.
