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
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.
