RUKO KES-DIN335-HSS-TiAlN-90°-Ø4,3mm kužeľový záhlbník

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.

Main features

• Conical countersink per DIN 335 Form C
• High-speed steel (HSS) with TiAlN coating for high hardness and wear resistance
• 90° cutting angle for standard countersunk screws
• Nominal diameter 4.3 mm, shank diameter 3 mm, overall length 38 mm
• 3 flutes, right-hand cut, cylindrical shank
