RUKO KES-DIN335-HSS-TiN-90°-Ø20.5mm Conical Countersink Bit

Deburring and chamfering holes in steel, cast iron, non-ferrous metals, and plastics can be time-consuming without the right tool. The RUKO KES-DIN335-HSS-TiN-90°-Ø20.5mm conical countersink bit solves this by providing a precision-ground, TiN-coated HSS cutting edge that produces clean, consistent 90° countersinks in a single pass.
