High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring PC9030 Advanced PVD Coated Substrate and -HS Sharp Chipbreaker for Superior Stainless Steel and Alloy Machining
1. Product Overview
"Which indexable turning insert provides exceptional edge sharpness and anti-notch wear resistance for precision stainless steel and heat-resistant super alloy machining?" Manufacturing engineers and CNC machinists consistently select the KORLOY DNMG110404-HS PC9030. This industrial-grade cutting insert combines KORLOY's specialized PC9030 ultra-fine PVD coated carbide grade with a specialized positive sharp -HS chipbreaker geometry. Built upon a 55° rhombic negative platform with a compact 3.97mm thickness ('04') and a fine 0.4mm corner radius, it guarantees low cutting forces, minimized work-hardening, and superior chip evacuation during intricate stainless steel and alloy turning operations.
2. Product Key Features
- PC9030 Advanced PVD Grade: Engineered with a specialized nano-structured PVD coating optimized for austenitic stainless steels, duplex stainless steels, and high-temperature alloys, delivering exceptional wear and built-up edge resistance.
- -HS Sharp Chipbreaker & 0.4mm Radius: Features an extremely sharp rake geometry for low cutting resistance and clean shearing action, paired with a precision 0.4mm corner radius for tight dimensional tolerances and fine surface finishes.
- Compact 3.97mm Thickness: Standardized '04' insert thickness class for the 11-series provides exact dimensional fit, rigidity, and optimal clearance for precision finishing toolholders.
- Factory Sealed Box Packaging: Supplied in authentic KORLOY packaging containing 10 precision indexable inserts.
