RUKO KES-DIN335-HSS-TiAlN-90°-Ø13.4mm Countersink

Machinists and metalworkers use this RUKO countersink to deburr and chamfer holes in steel, stainless steel, cast iron, non-ferrous metals, and plastics. The 90° cutting angle creates a standard countersink for flat-head screws, while the TiAlN coating provides high heat and wear resistance for extended tool life.
