RUKO LOS-HSSCo-108mm HSS-Co vrták do kovu 6,5mm DIN 338 Split Point

Drilling into stainless steel and alloyed steel demands a bit that resists heat and wear without wandering off the mark. The RUKO LOS-HSSCo-108mm twist drill bit is engineered for exactly that: a 5% cobalt-alloyed HSS body that holds its edge at high temperatures, paired with a 135° split point that starts on contact without a centre punch.

Who is it for

This bit suits metalworkers, maintenance technicians, and serious DIYers who regularly drill stainless steel, alloyed steel, cast iron, non-ferrous metals, and plastics. If you need clean, accurate holes in tough materials, this is the tool for the job.

Tips

Use cutting fluid when drilling stainless steel to extend bit life. For best results, start at a moderate speed and increase only if the bit cuts smoothly.
