High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring PC9030 Tough PVD Coated Substrate and -HS Sharp Chipbreaker for Superior Stainless Steel, Special Steel, and High-Temperature Alloy Precision Machining
1. Product Overview
"Which indexable turning insert provides exceptional edge sharpness and thermal crack resistance for precision finishing and light machining of stainless steel and heat-resistant superalloys?" Tooling specialists and CNC programmers frequently turn to the KORLOY DNMG150608-HS PC9030. This industrial-grade cutting tool combines KORLOY's specialized PC9030 nano-structured PVD coated carbide grade with a sharp, positive -HS precision finishing chipbreaker geometry. Built upon a rugged 55° rhombic negative platform featuring a heavy-duty 6.35mm thickness (designated by '06') and a 0.8mm corner radius, it delivers outstanding anti-built-up edge performance, low cutting forces, and flawless surface finishes on austenitic stainless steels, precipitation-hardening steels, and nickel-based alloys.
2. Product Key Features
- PC9030 Specialized PVD Grade: Engineered with a high-toughness carbide substrate and an advanced nano-structured PVD coating designed to resist thermal shock and chemical wear during stainless steel cutting.
- -HS Sharp Finishing Chipbreaker & 0.8mm Radius: Features a ground sharp rake face geometry designed to minimize cutting resistance and prevent work hardening, paired with a stable 0.8mm corner radius for fine surface finishes.
- Heavy-Duty 6.35mm Thickness Profile: The robust 6.35mm thickness ('06' designation) increases insert rigidity and vibration dampening during extended-reach turning operations.
- Factory Sealed Box Packaging: Supplied in original KORLOY protective packaging containing 10 pieces for secure storage and traceability.

8. Frequently Asked Questions (FAQ)
Q: How many inserts are included in one standard factory box?
A: Each original factory box contains exactly 10 pieces of DNMG150608-HS PC9030 inserts.
Q: Why is a sharp -HS chipbreaker recommended for stainless steel finishing?
A: Stainless steel tends to work-harden under cutting pressure. The sharp positive rake angle of the -HS chipbreaker reduces cutting forces, prevents built-up edge (BUE), and maintains superior surface finish quality.
Q: Are these indexable inserts fully compliant with ISO and ANSI standards?
A: Yes, all KORLOY inserts are manufactured strictly adhering to international ISO and ANSI dimension and coding standards, ensuring seamless interchangeability in standard toolholders.
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.
