RUKO SPB-DIN338-HSS-TiN-Ø14,0mm kierrepora

Precision drilling in tough metals demands a bit that stays sharp and centered. The RUKO SPB-DIN338-HSS-TiN 14.0 mm twist drill bit is built for exactly that—a high-speed steel core with a titanium nitride coating that reduces friction and heat, so it cuts cleanly through steel, cast iron, non-ferrous metals, and plastics without wandering.

Who is it for

Machinists, metalworkers, and serious DIYers who need reliable, accurate holes in metal up to 900 N/mm² tensile strength. If you're tired of bits that dull quickly or drift off-center, this precision-ground bit is your answer.

Tips

Use cutting fluid when drilling steel to maximize bit life and hole quality. For deep holes, retract periodically to clear chips and prevent overheating.
