How to use

Secure the workpiece and mark the drilling point before starting. Mount the 9 mm Proline drill bit in the drill chuck and tighten securely. Use appropriate cutting speed and feed for the metal being drilled, apply cutting fluid where recommended to reduce heat and extend tool life, and clear chips regularly. For best results, start with a center punch to prevent wandering and maintain a steady, axial feed while drilling.

Usage recommendations

Use lower spindle speeds and cutting lubricant when drilling harder steels; for thin sheet metals, support the workpiece to reduce vibration and burr formation. Store the drill bit in its plastic case to protect the cutting edge when not in use.
