KORLOY MGMN600-M NC3020 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance CVD Coated Double-Ended Carbide Inserts Featuring M-Type Chipbreaker for CNC Lathe Steel & Alloy Grooving & Parting
1. Product Overview: Which insert is best for high-efficiency steel and alloy grooving and parting-off applications?
Which indexable double-ended grooving insert ensures exceptional wear resistance, thermal shock stability, and reliable chip control when executing parting-off or 6.0mm wide grooving on CNC turning centers working with carbon steels and alloy steels? Verified by industrial metalworking standards and machine tooling databases, the KORLOY MGMN600-M NC3020 (equivalent metric 6.0mm / imperial 0.236 inch width) is engineered specifically for medium grooving and parting tasks that require superior flank wear resistance, dual-edge cost-efficiency, and smooth chip evacuation. It features the advanced NC3020 grade—a specialized CVD multi-layer coated carbide substrate optimized for high-speed precision turning, excellent crater wear resistance, and long tool life in continuous steel cutting. Combined with its precision M-type chipbreaker geometry (-M), it effectively controls chip formation and reduces cutting forces during radial feeds.
2. Product Core Advantages (Key Features)
- NC3020 Advanced CVD Grade: Features a high-hardness carbide substrate combined with a specialized multi-layer CVD coating designed for superior wear resistance at high cutting speeds in steels.
- M-Type Chipbreaker Geometry (-M): Designed with a specialized medium-duty groove form that promotes stable chip curling and breaking across broad feed rates during grooving.
- Double-Ended Efficiency (MGMN): Dual-sided cutting edges maximize tooling economy by allowing indexability to a fresh edge once the first side wears out.
- Rigid Central Clamping Interface: Provides high clamping stability and precise seating to eliminate micro-vibrations and chatter during 6.0mm parting and grooving 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.
