DORMER G57031.0 COUNTERSINK 31.00 MM 6381767

The Dormer G70 is a very robust HSS-Co 90° countersink drill, with AlTiCN coating (3700HV) for longer tool life in difficult-to-machine materials such as stainless steels but also highly alloyed materials such as Hardox. The combination of cobalt-alloyed HSS with the coating provides better resistance to high temperatures and increased wear resistance. Also suitable for dry machining.

Also highly suitable as a peripheral cutter, for deburring workpieces or for creating a 45° chamfer.

Dimensions according to DIN335C.
