High-Precision ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring KORLOY PC9030 Advanced PVD Coated Carbide Substrate and -HS Sharp Finishing Chipbreaker for Superior Surface Finish and Low Cutting Forces in Stainless Steel and Steel Machining
1. Product Overview
"Which indexable turning insert delivers superior surface finish and low cutting forces during precision profile turning of stainless steel and alloy steel components?" Advanced manufacturing engineers and CNC operators frequently look to the KORLOY DNMG150404-HS PC9030. This industrial-grade turning insert pairs KORLOY's high-performance PC9030 PVD multi-layer coated carbide grade with a specialized -HS sharp finishing chipbreaker geometry. Engineered with a 55° rhombic negative layout, a 15mm cutting edge length, a 4.76mm thickness ('04'), and a tight 0.4mm corner radius, it provides exceptional resistance to built-up edge (BUE) and thermal shock, securing dimensional accuracy and exceptional surface integrity during light finishing operations.
2. Product Key Features
- PC9030 Advanced PVD Coated Grade: Built upon a dedicated tough carbide substrate with a specialized fine-grained PVD coating structure, optimizing thermal stability and friction reduction for stainless steel turning.
- -HS Sharp Finishing Geometry: Features a sharp, low-resistance rake face engineered to minimize cutting forces, suppress vibration during slender part turning, and produce fine surface finishes.
- 55° Rhombic Versatility: The acute 55-degree apex angle provides excellent clearance for profiling, contouring, and multi-directional turning operations.
- Factory Sealed Packaging: Delivered in genuine KORLOY containers containing 10 premium indexable inserts.
