How to use

Secure the drill bit in a compatible chuck or holder rated for the bit diameter and length. Select drill speed and feed appropriate for the workpiece material and bit diameter; use cutting fluid or lubricant when drilling steel to reduce heat and improve tool life. Ensure the workpiece is clamped securely and start drilling with steady pressure, withdrawing periodically when making deep holes to clear chips and avoid overheating.

Usage recommendations

Use protective equipment, maintain correct speed and cooling, and verify drill compatibility with the machine’s chuck and power capacity before operation to achieve best results and prolong tool life.
