How to use

Secure the M14 core drill bit in the angle grinder according to the tool manufacturer’s instructions. Mark the drilling position on the workpiece and start at low speed to establish the cutting path, then increase speed as appropriate for the material. Apply steady, moderate pressure and avoid excessive side loads. Because the bit is intended for dry drilling, work in short intervals to prevent overheating; allowing the bit and material to cool between passes will extend tool life.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection, gloves and a dust mask. For best results on fragile tiles, consider using a guide or tape to prevent slipping at startup. If possible, test on a scrap piece of the same material to determine optimal speed and pressure.
