Machinists and metalworkers drilling stainless or acid-resistant steel rely on this RUKO SPB-DIN338-7.6mm-HSSCo twist drill bit. Its 5% cobalt high-speed steel body stays hard under heat, while the 135° split point starts on contact without wandering. The fully ground flutes clear chips fast in deep holes.

Key specifications

  • Material: HSS-Co (5% cobalt)
  • Standard: DIN 338
  • Diameter: 7.6 mm
  • Point angle: 135°
  • Point type: Split point
  • Shank: Cylindrical

Why choose it

The cobalt alloy withstands high drilling temperatures, so the cutting edges stay sharp longer in tough alloys. The split point reduces thrust pressure and prevents walking, giving you precise hole placement without a centre punch.

Ideal use cases

  • Drilling stainless steel, acid-resistant steel, and heat-resistant steel
  • High-alloy steels and cast iron
  • Bronze and plastics

Good to know

Fully ground flutes improve chip evacuation and reduce friction. The h8 tolerance ensures a consistent hole size for dowel pins or reaming operations.
