KORLOY MGMN200-M CN2000 Indexable Parting, Grooving & Turning Inserts (10pcs/box)
High-Performance PVD Coated Carbide Inserts with M-Type Chipbreaker for CNC Lathe Cut-Off and Precision Grooving
1. Product Overview: Which grooving insert is best for precision parting, superior thermal shock resistance, and stable tool life during CNC lathe machining?
Which indexable parting and grooving insert featuring specialized M-type chipbreaker geometry, high edge strength, and advanced PVD metallurgical coatings offers superior chip evacuation, minimal cutting resistance, and smooth surface finishes when executing deep grooving, cut-off, and profiling operations on CNC turning centers? Backed by certified metalworking research and industrial tooling parameters, the KORLOY MGMN200-M CN2000 (equivalent metric and imperial grooving configurations) is engineered specifically for stable, high-efficiency material removal across demanding industrial applications. It utilizes the advanced CN2000 grade—a specialized PVD coated carbide substrate optimized for high toughness, thermal stability, and superior resistance to flank wear and plastic deformation when machining carbon and alloy steels. Combined with its unique M-type geometry, it guarantees controlled chip curling, reliable chip breakage, and extended tool durability.
2. Product Core Advantages (Key Features)
- CN2000 Advanced PVD Grade: Features a high-toughness carbide substrate combined with a multi-layer PVD coating engineered to withstand extreme thermal stress and wear during steel parting and grooving.
- M-Type Chipbreaker Geometry: Designed with a versatile positive rake angle and specialized ground geometry that delivers excellent chip control and moderate chip curling across general machining feed rates.
- Indexable Economy: Precision-ground dual-edge design maximizes insert utilization, significantly lowering per-part production costs in high-volume lathe turning.
- Secure Clamping Stability: Engineered to fit securely into standard modular grooving blocks and blades, eliminating micro-vibration and ensuring high dimensional accuracy.
