For icon explanation, refer to P.50 Product features

  • AL+SP ensures the consistent tapping even in high speed cutting area, in forged workpieces of light alloys such as aluminum die castings and aluminum castings.
  • Having optimum cutting edge design, AL+SP does not produce burrs in minor diameter which usually tend to come out during tapping light alloys, and results in cutting of stable and clean internal threads.
