KORLOY MGMN500-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 stability, and reliable chip control when executing parting-off or 5.0mm wide grooving on CNC turning centers working with carbon steels and alloy steels? Verified by industrial metalworking standards and machine tooling databases, the KORLOY MGMN500-M NC3020 (equivalent metric 5.0mm / imperial 0.197 inch width) is engineered specifically for general-to-high-performance steel turning, 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 continuous to light interrupted cutting of steel alloys. 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-strength carbide substrate combined with a specialized multi-layer CVD coating designed for superior high-temperature wear resistance and extended tool life in steel machining.
- 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 5.0mm 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.
