Key Features

  • Powdered metal substrate offers superior performance that approaches that of solid carbide tools but with the toughness and shock-resistance of high-speed steel
  • Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • Round with square end shank
  • Blind hole
