Tips for best results
- Use a light cutting fluid or oil when drilling metals to extend bit life and improve hole quality.
- Maintain steady feed pressure and avoid forcing the bit; let the bit do the work at the appropriate speed for the material.
- For harder metals, start with a small pilot hole to guide the bit and reduce deflection.
- Keep chips cleared and reapply coolant as needed to prevent overheating and dulling.
