How to use

Secure the workpiece and mark the drilling point. Use a rotary or impact drill at low to moderate speed; apply steady, light pressure and avoid excessive force to prevent cracking. Cooling with water is recommended during drilling to reduce heat and prolong tool life. For best results, start with a shallow pilot groove or use masking tape on the surface to help guide the bit.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves). Match drill speed and pressure to the material and keep the bit cooled with water to minimize chipping and wear.
