Key specifications

• Tool type: twist drill bit
• Diameter: 8 mm
• Overall length: 117 mm
• Shank type: triangular shank for improved grip

How to use

Secure the twist drill bit in a compatible chuck, ensuring the triangular shank seats properly to prevent rotation. Select an appropriate drill speed and feed rate for the material: lower speeds for metals and higher speeds for wood and plastics. For metals and stainless steel, apply a suitable cutting fluid or coolant to reduce heat and extend tool life. Start drilling with a steady, perpendicular approach and apply consistent pressure; retract periodically to clear chips when drilling deep holes.

Usage recommendations

Use lower speeds and cutting fluid when drilling metals, especially stainless steel, and increase speed for wood and plastic. Replace the bit if signs of wear or chipping appear to maintain hole quality and operator safety.
