## Long description

Proline 91030 single metal drill bit, diameter 10 mm and overall length 300 mm, is designed for drilling metal where extra reach is required.

How to use
Secure the drill bit firmly in the chuck of a hand drill or drill press, ensuring proper alignment for a straight shank. Select an appropriate drill speed and apply steady, moderate pressure; use cutting lubricant when drilling harder metals to reduce heat and prolong tool life. Withdraw the bit periodically to clear chips if drilling deep holes, and finish using deburring tools if required to remove sharp edges.
Usage recommendations
For best results, use the Proline 91030 with a drill or press that provides stable support and appropriate speed control. Apply cutting fluid when working with high-strength steels, monitor temperature to avoid overheating the carbide tip, and replace the bit when wear affects centering or cutting efficiency.
