Why choose it

Ground from high-speed steel, this bit holds its edge longer than standard rolled bits and resists heat build-up during continuous drilling. The 118° point angle is a proven all-rounder that centers well and cuts efficiently in a wide range of metals.

Ideal use cases

• Drilling clearance and pilot holes in steel fabrications
• Maintenance and repair work on machinery and castings
• General workshop drilling in non-ferrous metals and plastics

Good to know

The bright finish reduces friction and helps clear chips from the flute, while the cylindrical shank fits standard drill chucks. With a working length of 69 mm, it reaches deep enough for most plate and profile work.
