Precise drilling.
The sturdy twist drill with its short design provides for precise drilling.

Self-centering.
Crosswise grinding ensures an excellent centering effect even on round
materials, eliminating the need for center-punching or piloting.

Noticeably longer service life.
Thanks to the TIN head-coating and the HC (high-speed cutting) grind.
Consistent drilled-hole quality and high precision are ensured thanks to the
associated precise cutting edge geometry.

TIN (Titan-Nitrid) coated.
HSS Steel has a maximum application temperature of 400º. The TIN
coating increase the heat resistance up to 600º, which results in up to 3
times more tool life in comparison with a non-coated HSS drill.

Drilling depth.
5x drill bit diameter.

Note:
