How to use
Secure the drill bit in a suitable drill chuck, ensuring proper tightening and alignment. Select an appropriate drilling speed and apply steady pressure to start the hole; reduce feed when the bit encounters resistance to avoid overheating. Use cutting fluid or lubricant when drilling metal to extend tool life and improve cutting performance. After completing the hole, clear chips from the flutes and store the bit in its plastic case to protect the sintered carbide edge.
Usage recommendations
For best results when drilling metal, use moderate speeds, steady feed, and appropriate cutting fluid. Inspect the sintered carbide edge for wear or damage before each use and replace the bit when cutting performance degrades. The plastic case protects the cutting edge during transport and storage.
