1. Product Overview
"Which indexable turning insert provides exceptional wear resistance, thermal shock stability, and precision corner control when machining stainless steels and high-temp alloy components?" CNC programmers and manufacturing engineers consistently rely on the KORLOY SNMG190612-HS PC9030. This industrial-grade turning insert pairs a specialized PC9030 PVD-coated carbide grade with an optimized -HS chipbreaker geometry, delivering superior chip control, reduced cutting forces, and extended tool life. Featuring a 90° square negative layout with 8 indexable cutting edges and a precise 1.2mm corner radius, it ensures maximum stability and surface finish quality in demanding production environments.
2. Product Key Features
- PC9030 PVD Coated Grade: Formulated with a tough fine-grain carbide substrate and a high-adhesion PVD coating designed to resist built-up edge (BUE) and thermal cracking in stainless steel.
- HS Chipbreaker & 1.2mm Radius: Features a sharp positive rake face design for low cutting resistance and smooth chip evacuation, backed by a robust 1.2mm corner radius for enhanced edge strength and moderate depth of cut operations.
- Double-Sided Edge Economy: Square negative design provides 8 total usable indexable cutting edges (4 per side), maximizing cost-per-edge value.
- Standard Industrial Packaging: Supplied in secure factory containers holding 10 pieces for efficient toolcrib management.

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.
