RUKO KES-DIN335-HSS-90°-Ø23.0mm Countersink

Deburring and chamfering holes in steel, cast iron, non-ferrous metals, and plastics demands a tool that cuts cleanly without chatter. The RUKO KES-DIN335-HSS-90°-Ø23.0mm countersink meets that need with a precision-ground 90° cutting angle and three flutes for smooth, controlled material removal.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to produce accurate countersinks for flat-head screws or deburr drilled holes in a variety of materials. It fits standard drilling machines and lathes with a 10 mm cylindrical shank.

Main features

• 90° cutting angle per DIN 335 Form C for standard countersunk screws.
