Drill bit GRAPHITE 7 mm titanium-coated cylindrical shank (57H142)
GRAPHITE 7 mm titanium-coated drill bit with a cylindrical shank is designed for drilling precise holes in metal, wood and plastics. The 7 mm diameter is suitable for common drilling tasks in workshops and home projects. The titanium coating reduces friction and increases wear resistance, extending tool life while maintaining cutting performance. The cylindrical shank fits standard chucks that accept straight-shank bits and provides stable rotation during use.
The titanium coating improves durability and reduces heat build-up during drilling, which helps preserve the cutting edge and prolong service life. The 7 mm diameter offers a balance between strength and versatility for general-purpose drilling. The straight cylindrical shank ensures compatibility with a wide range of handheld and bench drills and provides reliable concentricity for accurate holes.
Select a drill or driver with a chuck suitable for cylindrical shank bits and secure the bit firmly. Adjust drilling speed according to the material: use lower speeds for metals and higher speeds for wood and plastics. Apply steady, moderate pressure and allow the bit to cut without forcing; withdraw occasionally to clear chips when drilling deeper holes. For metal drilling, consider using cutting fluid to reduce heat and improve chip evacuation.
Inspect the bit for damage or excessive wear before use and replace when the cutting edge becomes blunt. Use appropriate personal protective equipment such as safety glasses and hearing protection. Store in a dry place to prevent corrosion and avoid using the bit on hardened steels or masonry to prevent premature wear.
