KORLOY MGMN250-G H01 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance Uncoated Micro-Grain Carbide Inserts with 2.5mm Width & -G Sharp Chipbreaker Geometry for CNC Lathe Aluminum & Non-Ferrous Turning
1. Product Overview: Which insert is best for mirror-finish grooving, low cutting resistance, and clean parting-off in aluminum and non-ferrous metals?
Which indexable grooving insert featuring a 2.5mm cutting width, an optimized -G sharp chipbreaker geometry, and a polished uncoated micro-grain carbide structure offers exceptional sharpness, anti-built-up edge properties, and superior surface finish when machining aluminum alloys, copper, brass, and plastics on CNC turning centers? Backed by certified metalworking research and industrial tooling parameters, the KORLOY MGMN250-G H01 (equivalent metric 2.5mm width with -G chipbreaker / imperial 0.098 inch width) is engineered specifically for stable, high-speed material removal across non-ferrous applications. It utilizes the advanced H01 grade—a specialized uncoated micro-grain carbide substrate optimized for extreme edge sharpness and high chemical inertness in aluminum turning. Combined with its designated -G geometry, it guarantees razor-sharp cutting action, low cutting forces, and extended tool life.
2. Product Core Advantages (Key Features)
- H01 Advanced Uncoated Grade: Features a high-purity micro-grain carbide substrate with a mirror-polished rake face designed to prevent built-up edge (BUE) and chemical adhesion when machining sticky non-ferrous materials.
- -G Sharp Chipbreaker Geometry: Designed with an ultra-sharp positive rake angle and narrow chip-forming pockets that significantly lower cutting resistance and produce burr-free surfaces on soft metals.
- 2.5mm Cutting Width & Dual-Edge Economy: Provides a robust 2.5mm width profile with two indexable cutting edges for maximum tool life and low per-part operational costs.
- Secure Pocket Clamping: Engineered to fit securely into standard external grooving tool blocks, eliminating micro-motion and vibration during high-speed feed rates.

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.
