Broca helicoidal RUKO SPB-DIN338-HSSCo8-TiAlN Ø15,0 mm

Drilling into tough materials like stainless steel, high-alloy steels, and cast iron can quickly dull ordinary drill bits, leading to poor hole quality and frequent replacements. The RUKO SPB-DIN338-HSSCo8-TiAlN twist drill bit solves this problem with its cobalt-alloyed high-speed steel and TiAlN coating, delivering exceptional heat and wear resistance for demanding metalworking tasks.

Who is it for

Professional machinists, metal fabricators, and serious DIYers who need a reliable, long-lasting drill bit for hard metals and heat-resistant alloys.
