How to use
Secure the drill bit in the drill chuck and tighten according to the drill manufacturer's instructions. Select an appropriate rotational speed and feed pressure for the specific metal being drilled; use slower speeds for harder metals and steady, moderate feed to avoid overheating. Apply cutting lubricant where recommended to extend tool life and improve cutting performance. Drill with steady pressure until the required hole depth is reached, then withdraw the bit periodically to clear chips when drilling deep holes.
Usage recommendations
For best results when drilling metal, use suitable cutting fluid, maintain correct drill speed and pressure, and ensure the workpiece is firmly clamped. Inspect the cutting edge before use and store the drill bit in its plastic case to prevent damage.
