RUKO KES-DIN335-HSS-TiAlN-90°-6,3mm escareador cónico

Creating clean, precise chamfers and countersinks in tough materials demands a tool that stays sharp and resists heat. This RUKO countersink bit, with its TiAlN-coated HSS body and 90° cutting angle, delivers exactly that—reliable performance for deburring and countersinking in steels, stainless steel, cast iron, non-ferrous metals, and plastics.

Who is it for

Machinists, metalworkers, and serious DIYers who need a durable, professional-grade countersink for frequent use in demanding applications. It fits standard drill chucks and collet chucks with its 6 mm straight shank.
