Precautions for Using a Wall Chaser?
Never perform two consecutive cuts, whether horizontally or vertically.
The depth of the groove affects wall stability. Vertical grooves should not exceed one-third of the wall thickness, and for hollow walls, the cut depth should not exceed one-third of the hollow wall’s thickness. Horizontal grooves should not exceed one-sixth of the wall thickness, and for hollow walls, the depth should not exceed one-sixth of the hollow wall’s thickness.
How to Reduce Dust When Using a Wall Chaser?

Our products can be equipped with a vacuum attachment, allowing a vacuum cleaner to be connected to the wall chaser. This significantly reduces dust generated during cutting and grooving.

Material Requirements for Magnetic Drills?

Magnetic drills require clean, smooth, and flat iron-based surfaces for the magnet to securely adhere. Iron-based materials include steel, carbon steel, alloy steel, cast iron, and wrought iron. For drilling non-ferrous metals, it is recommended to use a vacuum plate or securely clamp a steel plate in place.

Can a Magnetic Drill Be Used Horizontally or Upside Down?

Yes. A portable magnetic drill utilizes magnetic base adhesion to operate from various angles, including horizontal, vertical, and overhead (inverted) drilling. This allows on-site drilling without needing to move the workpiece to a drill press. When drilling on vertical or overhead surfaces, cutting paste is recommended instead of cutting fluid. Always secure the magnetic drill with a safety strap or safety chain.

How to Prevent a Magnetic Drill from Slipping?
Ensure the magnetic base is free of debris and securely positioned on a clean, flat surface. Uneven surfaces or excessive debris buildup can reduce the magnet’s holding force, causing the drill to shift or lift during operation.
If the drill shifts, a safety chain or strap helps prevent accidents.
If the drill lifts or moves during cutting, the tool is at risk of breaking.
