How to use

Select a compatible hex chuck or quick-change holder and secure the Diamond Crown Hex 14mm bit. Mark the drilling point, position the bit perpendicular to the work surface, and apply steady pressure at an appropriate rotational speed for the material being drilled. Retract periodically if drilling deeper holes to clear debris and reduce heat buildup. After use, remove the bit and inspect the cutting edge for wear before storing.

Usage recommendations

Use appropriate personal protective equipment, select drilling speeds and feed pressure suited to the work material, and ensure the hex shank is fully engaged in the chuck or holder to prevent slippage. For extended bit life, clear debris regularly and avoid excessive heat by using controlled feed rates or intermittent drilling.
