90° HSS COUNTERSINKS WITH ASYMMETRIC GEOMETRY OF THE 3 CUTTING EDGES

ASYMMETRIC GEOMETRY: the special asymmetric geometry, thanks to the different clearance angle of each cutting edge, ensures a perfect hole finish, resulting in a round and smooth hole.

HSS and HSS-CO: ideal tool for countersinking work on alloy steels, cast irons, all metals in general and, in the 5% cobalt version, also on stainless steel.
ANTI-SLIP FLATS: the shank is equipped with three ground surfaces [for Ø 12.4 mm] that guarantee maximum grip of the chuck jaws, eliminating the risk of tool slippage in the chuck.

Also available in the Cobalt version 01267 - 3-flute 90° countersinks with asymmetric geometry HSS CO.
