Drill bit Proline HSS-TiN 7.5 mm for metal and general use

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. The drill features a 135° split-point geometry with adjustable chisel angle to reduce walking and produce precise holes. Diameter 7.5 mm, working length 69 mm, overall length 109 mm.

Advantages

The TiN coating increases surface hardness and reduces friction, resulting in longer service life and better hole finish when drilling metal, wood or plastics. The 135° split-point tip with adjustable chisel angle helps start holes more accurately and minimizes the need for pilot drilling. Compatible with both handheld and stationary drills for workshop and construction tasks.

Suitable for

• Drilling steel and non-ferrous metals
• General workshop drilling in wood and plastics
• Handheld and drill-press operations
• Applications requiring accurate, clean holes

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.
