RUKO KES-DIN335-HSS-TiAlN-90°-Ø19,0mm kartiopora

Deburring and chamfering holes in metal workpieces can be time-consuming and leave rough edges. This RUKO countersink bit solves that by providing a precise 90° chamfer in a single pass, eliminating sharp burrs and creating a clean, professional finish. It is suitable for use in steel, stainless steel, cast iron, non-ferrous metals, and plastics.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to deburr drilled holes or create countersinks for flat-head screws. It works in drill presses, milling machines, and hand drills with a suitable chuck.
