RUKO SPB-DIN338-HSS-TiN-Ø10,2mm σπειροειδές τρυπάνι

Drilling into alloyed steel, cast iron, or tough non-ferrous metals quickly dulls ordinary bits, forcing frequent replacements and uneven holes. The RUKO SPB-DIN338-HSS-TiN Ø10.2 mm twist drill bit solves this with a titanium nitride coating that reduces friction and withstands temperatures up to 600°C. Ground from solid high-speed steel to DIN 338, it delivers precise, clean holes in demanding workshop tasks.

Who is it for

Professional machinists, metalworkers, and serious DIYers who need a reliable general-purpose drill bit for alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics. Its 10.2 mm diameter suits clearance holes for M10 bolts or precision dowel holes.

Main features

Tips

Use cutting fluid when drilling steel to extend bit life. For deep holes, withdraw the bit periodically to clear chips. Ensure the workpiece is securely clamped to prevent wandering.
