RUKO KES-UC-DIN335-HSSCo-RT-90°-Ø23,0mm-3S svasatore, HSS-Co, 90°, 23 mm, 3 taglienti

With a 23 mm cutting diameter and 90° cutting angle, this HSS-Co countersink delivers clean, chatter-free chamfers in steel, stainless steel, cast iron, non-ferrous metals, and plastics. The 3-flute geometry and ground profile ensure smooth cutting and long tool life, while the 10 mm cylindrical shank fits standard drill chucks and collets.

Overview

The RUKO GMBH KES-UC-DIN335-HSSCo-RT-90°-Ø23,0mm-3S is a high-performance countersink bit engineered to DIN 335 C standards. It is manufactured from HSS-Co (high-speed steel with cobalt), which provides enhanced heat resistance and wear resistance compared to standard HSS. The right-hand cutting direction and 3-flute design allow efficient chip evacuation and reduced cutting forces.
