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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
