Product Features

  • Stable screw tapping in light alloy castings such as aluminum die casting and aluminum casting even at a high speed range.
  • Optimum design of the flute makes it possible to produce stable and clean internal threading with fewer burrs on the inner diameter that normally occur in tapping of light alloys.
