KORLOY DNMG150604-HS PC9030 Indexable Carbide Turning Inserts | DNMG621-HS PC9030 (ANSI Equivalent) PVD Coated Carbide Inserts for Finishing Stainless Steel & Heat-Resistant Alloys - 10pcs/box
High-Precision ISO-Standard 55° Rhombic Negative Indexable Finishing Cutters Featuring PC9030 Advanced PVD Coated Carbide Substrate and -HS Sharp Finishing Chipbreaker for Superior Stainless Steel and Heat-Resistant Alloy Machining
1. Product Overview
"Which indexable turning insert is best suited for precision finishing of stainless steel and heat-resistant alloys while minimizing cutting forces and burr formation?" Manufacturing engineers and CNC machinists frequently specify the KORLOY DNMG150604-HS PC9030. This industrial-grade cutting tool combines KORLOY's specialized PC9030 multi-layer PVD coated carbide grade with a sharp, low-cutting-force -HS finishing chipbreaker geometry. Engineered on a robust 55° rhombic negative platform featuring an increased 6.35mm thickness (designated by '06') and a precise 0.4mm corner radius, it delivers exceptional surface finish quality, reduced work-hardening, and reliable chip control during light-to-medium finishing passes on austenitic stainless steels and superalloys.
2. Product Key Features
- PC9030 Advanced PVD Grade: Developed with an ultra-thin, high-hardness physical vapor deposition coating optimized for stainless steel and heat-resistant alloy finishing, offering superior resistance to chemical wear and edge chipping.
- -HS Sharp Chipbreaker & 0.4mm Radius: Features a positive sharp cutting edge geometry designed to drastically reduce cutting resistance and prevent burrs during finishing, paired with a 0.4mm corner radius for tight dimensional tolerances.
- Thicker 6.35mm Substrate Profile: The heavy-duty 6.35mm thickness ('06' designation) provides enhanced mechanical stability and thermal rigidity under high-precision cutting conditions.
- Factory Sealed Box Packaging: Supplied in original KORLOY protective packaging containing 10 pieces for dependable inventory tracking and verified authenticity.

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 DNMG150604-HS PC9030 inserts.
Q: How does the -HS chipbreaker differ from general-purpose geometries?
A: The -HS chipbreaker features a sharper cutting edge and positive rake designed specifically for low cutting depths and light finishing passes, minimizing burrs and cutting forces on sensitive materials.
Q: Is this insert suitable for heavy roughing cuts?
A: No, the -HS geometry is optimized for precision finishing and light machining. For heavy roughing operations, use medium or roughing chipbreakers such as -HM or -HR.
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.
