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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
