KORLOY MGMN300-M PC9030 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance PVD Coated Double-Ended Carbide Inserts Featuring M-Type Chipbreaker for CNC Lathe Stainless Steel & Alloy Grooving & Parting
1. Product Overview: Which insert is best for high-reliability stainless steel and alloy grooving and parting-off?
Which indexable double-ended grooving insert offers exceptional edge toughness, thermal shock resistance, and reliable chip control when performing parting-off or 3.0mm wide grooving on CNC turning centers machining austenitic stainless steels, heat-resistant alloys, and carbon steels? Backed by industrial metalworking standards and empirical tooling data, the KORLOY MGMN300-M PC9030 (equivalent metric 3.0mm / imperial 0.118 inch width) is engineered specifically for stainless steel turning, external grooving, and parting applications requiring high chemical stability and consistent wear resistance. It incorporates the premium PC9030 grade—a specialized PVD nano-structured multi-layer coated carbide substrate designed to resist built-up edge (BUE) and thermal cracking. Coupled with its optimized M-type chipbreaker geometry (-M), it ensures reliable chip evacuation and low cutting resistance.
2. Product Core Advantages (Key Features)
- PC9030 Advanced PVD Grade: Features a high-toughness carbide substrate combined with a specialized nano-PVD coating designed to resist adhesive wear and thermal shock during stainless steel cutting.
- M-Type Chipbreaker Geometry (-M): Engineered with a medium-duty groove form that promotes clean chip curling, reducing cutting forces and preventing stringy chip entanglement.
- Double-Ended Economy (MGMN): Dual cutting edges double the utility per insert, delivering maximum cost efficiency for production turning environments.
- Secure Clamping Stability: Designed for precise seating in standard tool blocks to eliminate micro-vibrations and chatter during deep parting passes.

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.
