1. Product Overview
"Which indexable turning insert provides exceptional thermal shock resistance and reliable chip control when machining austenitic and martensitic stainless steel components?" CNC machinists and manufacturing specialists repeatedly turn to the KORLOY TNMG160404-HM PC9030. This industrial-grade cutting insert pairs an advanced PC9030 PVD multi-layer coated carbide grade with a specialized -HM general medium-to-roughing chipbreaker, delivering high fracture toughness, superior work-hardening suppression, and dependable chip evacuation. Featuring a 60° triangular negative geometry for economic multi-edge utilization and a tight 0.4mm corner radius, it guarantees strict tolerance control and premium surface integrity in demanding stainless steel turning operations.
2. Product Key Features
- PC9030 Advanced PVD Coated Grade: Combines a tough fine-grain carbide substrate with a specialized PVD nano-multilayer coating optimized for high thermal shock resistance, notch wear suppression, and anti-built-up edge performance in stainless steel.
- HM General Chipbreaker & 0.4mm Radius: Designed with a robust dual-stage groove geometry to control chip flow effectively across various feed rates while offering fine contouring capability with a 0.4mm corner radius.
- ISO Standard Compliance: Manufactured strictly according to international coding standards for secure mechanical clamping and dependable tool repeatability across multi-axis lathes.
- Standard Industrial Packaging: Supplied in protective factory boxes containing 10 pieces for straightforward inventory control and shop floor management.
