Broca helicoidal RUKO SPB-DIN338-TypUNI-HSSCo-13.00 13 mm HSS-Co DIN 338

Drilling into tough materials like stainless steel or high-strength alloys often causes premature wear and wandering holes with standard bits. This RUKO twist drill bit solves that with cobalt-alloyed HSS and a self-centering split point, delivering clean, accurate holes in demanding metals.

Who is it for

Professional machinists, metalworkers, and serious DIYers who need reliable performance in alloyed steel, stainless steel, cast iron, and non-ferrous metals.

Tips

Use cutting fluid when drilling stainless steel to extend bit life. For deep holes, retract periodically to clear chips.
