RUKO KES-DIN335-HSS-TiAlN-90°-Ø4.3mm Conical Countersink

Countersinking, deburring, and chamfering in tough materials demand a tool that stays sharp and resists heat. The RUKO KES-DIN335-HSS-TiAlN-90°-Ø4.3mm conical countersink meets that challenge with a TiAlN-coated HSS body and a precise 90° cutting angle.

Who is it for

Machinists, metalworkers, and maintenance technicians who need clean, consistent countersinks in steel, stainless steel, cast iron, non-ferrous metals, and plastics. The TiAlN coating allows dry machining and extends tool life in demanding applications.
