High-Performance ISO-Standard 90° Square Negative Indexable Turning Cutters Featuring PC5300 PVD Coating and -HS High-Strength Chipbreaker for Stainless Steel Turning Applications
1. Product Overview
"Which indexable turning insert is best suited for stable, reliable machining of austenitic and martensitic stainless steel components under continuous or light interrupted cutting conditions?" CNC operators and manufacturing engineers consistently select the KORLOY SNMG120408-HS PC5300. This industrial-grade turning insert combines a tough, wear-resistant PC5300 PVD-coated carbide substrate with an optimized -HS chipbreaker geometry, delivering excellent thermal resistance, secure chip evacuation, and extended tool life across demanding stainless steel turning operations. Built on a rigid 90° square negative outline with 8 indexable cutting edges and a durable 0.8mm corner radius, it guarantees exceptional productivity and structural dependability.
2. Product Key Features
- PC5300 PVD Coated Grade: Formulated with a dedicated tough carbide substrate and advanced PVD multi-layer coating designed to resist built-up edge (BUE) and thermal cracking in stainless steel machining.
- -HS Chipbreaker & 0.8mm Radius: Features a robust cutting edge geometry engineered for stable feed rates and depth-of-cut flexibility, paired with a reliable 0.8mm corner radius for improved surface finish.
- Double-Sided Indexable Economy: Square negative configuration provides 8 total indexable cutting edges (4 per side), minimizing tooling costs per component.
- Standard Industrial Packaging: Delivered in secure factory containers containing 10 pieces for efficient workshop inventory control.
