RUKO SPB-DIN1897-HSSCo-Ø3,2mm kort-serie HSS-Co spiraalboor

Precision-ground from solid HSS-Co with 5% cobalt, this short series twist drill bit delivers exceptional heat resistance and durability when drilling high-alloy steels, stainless steel, cast iron, bronze, and hard plastics.

Overview

Manufactured to DIN 1897 short series standards, this 3.2 mm drill bit features a bright finish, cylindrical shank, and a 135° split point for self-centering starts without a centre punch. The h8 tolerance ensures consistent hole quality, while the right-hand cutting direction suits standard drilling machines.
