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
- TiN coating yields a hardness of approximately 2300 HV and also a heat-resistant up to approximately 600 deg C
- The current coating is an excellent all round coating for normal applications
