With a 12.1 mm cutting diameter and 5% cobalt alloy, this twist drill bit tackles stainless steel, high-alloy steel, and cast iron without losing its edge.

Overview

The RUKO LOS-HSSCo-121mm is a jobber-length twist drill bit made from HSS-Co (high-speed steel with 5% cobalt). Its 135° split point starts on contact, reducing walking and eliminating the need for a centre punch. The bright finish and fully ground flutes ensure smooth chip evacuation and precise holes in demanding materials.

What stands out

  • Cobalt alloy withstands high heat, preserving hardness during continuous drilling.
  • Split point self-centres, improving accuracy on curved or smooth surfaces.
  • DIN 338 geometry with h8 shank tolerance fits standard drill chucks.
  • Suited for stainless steel, high-alloy steel, cast iron, non-ferrous metals, and plastics.

Technical details

  • Material: HSS-Co (5% cobalt)
  • Cutting diameter: 12.1 mm
  • Overall length: 151 mm

  • Point angle: 135° split point

Our verdict

A professional-grade cobalt drill bit that delivers clean, accurate holes in tough metals, built to last under high-temperature conditions.
