High-Performance ISO-Standard 90° Square Negative Indexable Turning Cutters Featuring PC9030 PVD Coating and -HS High-Strength Chipbreaker for Medium-to-Heavy Turning Applications
1. Product Overview
"Which indexable turning insert is best suited for robust, medium-to-heavy turning operations on carbon steel and alloy steel components under interrupted cutting or high feed conditions?" CNC operators and manufacturing engineers consistently turn to the KORLOY SNMG120408-HS PC9030. This industrial-grade turning insert pairs an impact-resistant, wear-optimized PC9030 PVD-coated carbide substrate with a sturdy -HS chipbreaker geometry, ensuring exceptional edge strength, reliable chip control, and extended tool life across demanding roughing and semi-finishing passes. Built on a rigid 90° square negative outline with 8 indexable cutting edges and a strong 0.8mm corner radius, it delivers maximum productivity and structural integrity.
2. Product Key Features
- PC9030 PVD Coated Grade: Designed with a tough sub-micron carbide matrix and specialized PVD multi-layer coating engineered to resist thermal shock and mechanical fatigue in steel turning.
- -HS Chipbreaker & 0.8mm Radius: Features a reinforced cutting edge geometry designed to withstand higher feed rates and depth-of-cut variations, paired with a robust 0.8mm corner radius to prevent chipping.
- Double-Sided Indexable Economy: Square negative design provides 8 total indexable cutting edges (4 per side), ensuring low per-edge tooling costs.
- Standard Industrial Packaging: Delivered in secure factory containers containing 10 pieces for efficient toolcrib organization.
