SCT suggest all our custoemr to use our tool-holder to pair our inserts.
That not only help promote grooving efficiency and grooving precision, but also help extend inserts' working life. Below is the production process:
42CrMo Forging → Tempering → Rough Processing → Quenching → Fine Machining
→ Surface Blackening → Packaging → Warehousing
