Broca helicoidal RUKO SPB-DIN338-TypUNI-HSSCo-13,00-SB 13 mm HSS-Co DIN 338

Drilling into tough materials like stainless steel or alloyed steel demands a bit that stays sharp and resists heat. The RUKO SPB-DIN338-TypUNI-HSSCo-13,00-SB twist drill bit is built for exactly that, with a 5% cobalt alloy that holds its edge under high temperatures.

Who is it for

This bit suits metalworkers, machinists, and serious DIYers who regularly drill stainless steel, alloyed steel, unalloyed steel, cast iron, or non-ferrous metals. Its universal Type UNI design makes it a reliable general-purpose choice for workshops and job sites.

Tips

Use a cutting fluid or lubricant when drilling stainless steel to extend bit life. For best results, start with a center punch or pilot hole to guide the bit. Keep the bit sharp; a dull bit generates more heat and can work-harden the material.
