Highly accurate drilling
The robust twist drill with a short design ensures highly accurate drilling
Self-centring
The cross-ground finish ensures a good centring effect even on round materials, eliminating the need for centre punch marking/piloting
Long service life
HC (High Speed Cutting) grinding and the associated precise cutting geometry ensure consistent drilled hole quality while at the same time guaranteeing a high degree of precision and a long service life
Outstanding chip removal
The bare spiral groove ensures excellent chip removal from the drilled hole
