## Summary description

Proline HSS-TiN 10.0 mm drill bit (model 5154521) is made of high-speed steel with a titanium nitride (TiN) coating for improved wear resistance and longer life.

Standard 10 mm diameter provides compatibility with common chucks and offers stable cutting performance and corrosion protection.

## Long description

Proline HSS-TiN 10.0 mm (model 5154521) is a high-speed steel drill bit with a titanium nitride (TiN) coating designed for drilling precise holes in metal, wood and plastics. The bit has a 10 mm diameter, a working length of 87 mm and an overall length of 133 mm. Ground flutes and an adjustable 135° split-point angle improve cutting performance and hole finish while the TiN coating increases wear resistance and extends tool life.
Advantages
The TiN coating reduces friction and improves durability, while the HSS core maintains hardness and heat resistance during high-speed drilling. The 135° split-point with slope adjustment reduces walking at the start of drilling and provides cleaner hole edges. Ground flutes ensure efficient chip evacuation and consistent cutting.
Suitable for
Drilling through metal (steel, sheet metal)
Drilling in wood and composite materials
Working with plastics and acrylics
General workshop and DIY projects requiring a 10 mm hole

How to use
