Multi-Purpose and Blind Hole Applications
  • Combo tap's geometry is designed to provide smooth chip evacuation resulting in uninterrupted manufacturing
  • Guaranteed process reliability even in less rigid machining conditions
  • Prevents over and under feeding by its optimized flank geometry
  • Constant threading quality preventing oversized threading
  • HSS-E for prevention of oversized threads
  • The TiCN brings advantages for machining very difficult steels or cutting interrupted bores
  • The TiCN coating has a hardness of approximately 3000 HV, but is heat resistance only holds up to approximately 400 deg C, meaning that the TiCN needs an excellent cooling system for a long service life
  • Without coolant through hole
