Product Selling Points

Forged from hardened cobalt-containing high-speed steel with a premium TiN coating, this fine-thread machine tap delivers reliable cutting performance for tough material tapping. It covers standard metric sizes from M3 to M8, specially engineered for stainless steel and high-strength alloy machining.

The cobalt-enhanced substrate delivers outstanding thermal hardness and edge toughness, effectively resisting chipping and abrasive wear during continuous high-speed operation. The TiN coating lowers friction and prevents material adhesion, ensuring smooth chip evacuation and precise 6H thread dimensional accuracy.

Compatible with standard tapping machines, drill presses and CNC machining centers, it works reliably in both through and blind hole scenarios. It delivers uniform batch quality at a competitive price, ideal for precision hardware, electronics and automotive component manufacturing.
