SGSDrill for Heat-Resistant Alloys

  • General Features SGS type drills for heat-resistant alloys employ a sharp cutting edge to reduce heat during drilling (reduced cutting resistance) and provide stable and long tool life.
  • Characteristics Applications
  • Stable and long tool life
  • Combination of optimised cutting edge design and special grade significantly reduces wear.
  • Minute honing (edge treatment) amount and special thinning shape reduce cutting resistance. This reduces cutting edge breakage.
  • Perfect for drilling Ni-based heat resistant alloys (Inconel/Waspaloy/Hastelloy).
