How to use

Secure the twist drill bit in the drill chuck or compatible bit holder ensuring the triangle shank seats properly to prevent rotation. Select an appropriate drill speed and feed rate for the material being drilled; use lower speeds for stainless steel and higher speeds for wood and plastics. Apply steady pressure and allow the bit to cut without excessive force. For metal and stainless steel, use a suitable coolant or cutting fluid to reduce heat and extend tool life. After drilling, clear chips from the hole and, if necessary, deburr edges for a clean finish.

Usage recommendations

For optimal life and performance when drilling stainless steel, use coolant and reduced speed. When working with sheet metal, clamp the workpiece securely to avoid vibration. Replace the bit if wear or chipping is visible to maintain hole quality and operator safety.
