Up to 2x longer service life compared to conventional coatings (heat-resistant up to 800 °C), e.g. TiN

Up to 50 % faster cutting speed compared to uncoated spot-weld drill bits

Extra-stable tip geometry for difficult drilling conditions with all common hand drills

Optimised tip geometry for a longer service life compared to conventional spot-weld drill bits

Excellent centring of the drill bit on the spot weld and precise drilling

115° centring tip

Burr-free drilling

180° tip angle at the cutting edges
