High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring PC9030 Advanced PVD Coated Carbide Substrate and -HS Sharp Chipbreaker for Low Cutting Forces and Superior Wear Resistance in Stainless Steel and Heat-Resistant Alloy Machining
1. Product Overview
"Which indexable turning insert provides low cutting resistance, exceptional toughness, and built-up edge resistance for stainless steel and high-temperature alloy machining?" CNC programmers and precision machining specialists frequently select the KORLOY DNMG110408-HS PC9030. This industrial-grade cutting insert combines KORLOY's specialized PC9030 PVD coated carbide grade with a specialized -HS sharp chipbreaker geometry. Built upon a 55° rhombic negative platform featuring a 3.97mm thickness ('04') and a robust 0.8mm corner radius, it minimizes cutting forces, suppresses thermal shock, and delivers superior surface integrity across austenitic stainless steels, precipitation-hardening steels, and difficult-to-machine alloys.
2. Product Key Features
- PC9030 Advanced PVD Carbide Grade: Engineered with a high-adhesion nano-structured PVD coating over a tough, micro-grain carbide substrate designed to resist notch wear, thermal cracking, and built-up edge during stainless steel processing.
- -HS Sharp Chipbreaker & 0.8mm Radius: Features a positive rake, sharp cutting edge geometry for smooth chip formation at lower feed rates, paired with a reliable 0.8mm corner radius to ensure stable finishing and semi-finishing performance.
- Compact 3.97mm Thickness: Standardized '04' insert thickness class for the 11-series guarantees exact clamping stability, high rigidity, and reliable repeatability under fine tolerance machining conditions.
- Factory Sealed Box Packaging: Supplied in authentic KORLOY packaging containing 10 precision indexable inserts.

8. Frequently Asked Questions (FAQ)
Q: How many carbide inserts are contained in a standard factory box?
A: Each original factory box contains exactly 10 pieces of DNMG110408-HS PC9030 inserts.
Q: Why is the -HS chipbreaker recommended for stainless steel machining?
A: The sharp -HS geometry lowers cutting resistance and minimizes work-hardening on stainless steel surfaces, ensuring cleaner cuts and longer tool life during finishing.
Q: Are these indexable inserts fully compatible with standard ISO and ANSI toolholders?
A: Yes, they are manufactured strictly to ISO and ANSI international standards to ensure secure seating in any standard negative turning holder.
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.
