RUKO Countersink Bit DIN 335 C HSS TiN 90° Ø16.5 mm

Deburring and chamfering holes in steel, cast iron, non-ferrous metals, and plastics often requires a tool that can withstand high temperatures and resist wear. The RUKO countersink bit with a 90° cutting angle and 16.5 mm cutting diameter is made from high-speed steel with a titanium nitride coating, providing increased hardness and reduced friction for clean, precise countersinks.

Who is it for
