Multi-Purpose 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
- Reduces tap breakage, ensures accurate thread depth
- Eliminates loose threads due to tap overfeeding
- Improves thread quality and chip evacuation
- Allows tapping of many metals including stainless steel and steels
- Eliminates bird nest around tap shank
- Without coolant through hole
