When it comes to installing electrical conduits or pipes, the grooving machine is the necessary tool! Equipped with two diamond discs, it digs vertical or horizontal grooves of constant depth and width in most walls and partitions, whether brick, block, cellular concrete or plaster.

Two diamond discs
The grooving machine should be used with segment rim or full rim diamond discs. The first cut most building materials (concrete, cinder block, brick, cellular concrete...). Solid discs are for use in tiles or plasterboard for more delicate cuts. Never use abrasive discs. Used, both discs must be changed at the same time to ensure maximum efficiency.
Installation and settings of the wall chaser
- The direction of rotation
- Dust extraction
- Secure startup
Be careful, the discs are still running for a few seconds.
Machines at all prices
On average, the size of a kerf does not exceed 40 mm wide and 25 mm deep.
- If the grooves are to be made in plasterboard partitions or plasterboard, a power of 1200 to 1400 W is enough with discs Ø 125 mm.
- For load-bearing walls made of bricks or blocks, engines from 1500 to 2000 W are more enduring. They are often accompanied by Ø 150 or 180 mm discs.
Grooving with two hands
- A grooving machine handles with both hands.
- With the discs running at full speed, press the back of the machine onto the path and gently tip it toward the support.
- The machine moves backwards.
- She works in the opposite direction of the rotation of the discs that turn forward.
- To obtain a regular bleed, it must be done at once and without stopping.
- To facilitate the maneuver, a stabilizer wheel located on one side of the grooving machine, prevents the machine to skid and deviate from its path.
- According to the standards in force, the slits must never be practiced at an angle.
- They must cross perpendicularly.
- At the intersection, a slight cut can be made at an angle so that the sheath can pass without making a right angle.
- The cut is complete, it remains to hollow out bleeding.
- The best technique is to use a hammer and a flat chisel.
- Position the chisel on the edge of the part to be removed and then tap with the hammer.
- Then slide the sheath and fill in the bleeding.
Tips from handymen
For any installation, the Electric wires must be inserted in ducts before being concealed in the bleeding.
To save time, slip the future sheath or pipe between the groove discs and adjust the cutting width as closely as possible.
Finally, before starting a bleeding in a wall or a partition, make sure that there is no obstacle, such as a metal wall jamb, an electrical sheath... The use of a material detector can then be very useful to avoid unpleasant surprises.
