KORLOY MGMN300-G CN2000 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance PVD Coated Double-Ended Carbide Inserts Featuring G-Type Chipbreaker for CNC Lathe Non-Ferrous & Alloy Grooving & Parting
1. Product Overview: Which insert is best for high-efficiency non-ferrous and alloy grooving and parting-off?
Which indexable double-ended grooving insert offers exceptional edge sharpness, low friction, and smooth chip evacuation when executing parting-off or 3.0mm wide grooving on CNC turning centers machining aluminum, non-ferrous metals, and specialty alloys? Backed by industrial metalworking standards and empirical tooling data, the KORLOY MGMN300-G CN2000 (equivalent metric 3.0mm / imperial 0.118 inch width) is engineered specifically for precision grooving and parting tasks that require razor-sharp cutting edges, dual-edge cost efficiency, and robust structural stability. It incorporates the advanced CN2000 grade—a specialized PVD coated carbide substrate optimized for excellent anti-welding properties and low cutting resistance. Combined with its precision G-type chipbreaker geometry (-G), it effectively controls chip formation and minimizes built-up edge (BUE) during high-speed machining.
2. Product Core Advantages (Key Features)
- CN2000 Advanced PVD Grade: Features a high-toughness tungsten carbide substrate combined with a smooth PVD coating designed to prevent material adhesion and built-up edge in non-ferrous machining.
- G-Type Chipbreaker Geometry (-G): Engineered with a sharp, positive rake groove form that promotes clean shearing and smooth chip evacuation at lower-to-medium feed rates.
- 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 3.0mm 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.
