RUKO HGB-DIN2181-HSS-60°-3/4x Avellanador cónico, diámetro de corte 19 mm, 3 filos, HSS, DIN 2181

Creating clean, precise conical seats for countersunk screws in metal or plastic often requires a tool that can handle high speeds without dulling. The RUKO HGB-DIN2181-HSS-60°-3/4x countersink bit is engineered for exactly that task. With a 60° cutting angle and three precision-ground flutes, it produces smooth, chatter-free chamfers and deburrs edges in a single pass.

Who is it for

This countersink is intended for machinists, metalworkers, and maintenance professionals who need a reliable tool for deburring, chamfering, and creating conical seats in steel, cast iron, non-ferrous metals, and plastics. It fits standard drilling machines and hand drills with a cylindrical shank.
