High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring PC9030 Advanced PVD Coated Substrate and -HM Chipbreaker for Superior Stainless Steel and Heat-Resistant Alloy Machining
1. Product Overview
"Which indexable turning insert provides exceptional wear resistance and thermal shock stability when machining smaller components or precision stainless steel and high-temperature alloy parts?" Manufacturing engineers and CNC machinists consistently select the KORLOY DNMG110404-HM PC9030. This industrial-grade cutting insert combines KORLOY's specialized PC9030 nano-structured PVD coated carbide grade with a double-sided positive -HM 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 superior edge security, excellent built-up edge resistance, and predictable chip evacuation during demanding small-part stainless steel turning operations.
2. Product Key Features
- PC9030 Advanced PVD Grade: Engineered with a specialized multi-layer PVD coating optimized for stainless steel and alloy turning, delivering high oxidation resistance and anti-adhesion properties.
- -HM Chipbreaker & 0.4mm Radius: Features an optimized groove design for steady chip control at medium feeds, paired with a precision 0.4mm corner radius for tight dimensional tolerances and smooth surface finishes.
- Compact 3.97mm Thickness: Standardized '04' insert thickness class for the 11-series provides exact dimensional fit and rigidity for compact toolholders.
- Factory Sealed Box Packaging: Supplied in authentic KORLOY packaging containing 10 precision indexable inserts.
