## Long description

Proline HSS-TiN 7.5 mm drill bit for metal and general use, made of high-speed steel with a titanium nitride (TiN) coating that improves wear resistance and extends tool life.

How to use
Secure the drill bit in the drill chuck and tighten firmly. Mark the drilling position and, if necessary, use a center punch to prevent walking. Select an appropriate cutting speed and feed for the material: lower speeds for hard metals, higher speeds for softer metals and wood. Apply steady pressure and allow the drill to cut without excessive force. For metal drilling, use cutting fluid to reduce heat and prolong bit life. Clear chips periodically to avoid clogging.
Usage recommendations
For best results when drilling metal, use cutting fluid, moderate speed, and intermittent pecking on deep holes to clear chips. Store the TiN-coated bit in a dry place and avoid using it on masonry or concrete.
