Multi-layers coating G3Fully ground HSS drill bit Tialn coating
- High cutting speed
HSS G3 drill bit has a TiAlN coating that acts as a thermal barrier and reduce friction to facilitate chip evacuation. Drilling non-alloy and alloy steels (up to 1100N/mm²), cast iron, aluminium.
– Multi-layers Tialn coating.
– Fully ground HSS drill bit.
– Split point 135°.
– DIN 338 – S type flute.
– Diameter tolerance h8.
– Priming accuracy at start-up.
– Multiple coating acts as a thermal barrier against heating and allows a longer lifetime.
– The coating reduce friction, facilitate dust removal and increases cutting speed.
