KORLOY MGMN300-M PC9030 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance PVD Coated Double-Ended Carbide Inserts Featuring M-Type Chipbreaker for CNC Lathe Stainless Steel & Alloy Grooving & Parting
1. Product Overview: Which insert is best for high-reliability stainless steel and alloy grooving and parting-off?
Which indexable double-ended grooving insert offers exceptional edge toughness, thermal shock resistance, and reliable chip control when performing parting-off or 3.0mm wide grooving on CNC turning centers machining austenitic stainless steels, heat-resistant alloys, and carbon steels? Backed by industrial metalworking standards and empirical tooling data, the KORLOY MGMN300-M PC9030 (equivalent metric 3.0mm / imperial 0.118 inch width) is engineered specifically for stainless steel turning, external grooving, and parting applications requiring high chemical stability and consistent wear resistance. It incorporates the premium PC9030 grade—a specialized PVD nano-structured multi-layer coated carbide substrate designed to resist built-up edge (BUE) and thermal cracking. Coupled with its optimized M-type chipbreaker geometry (-M), it ensures reliable chip evacuation and low cutting resistance.
2. Product Core Advantages (Key Features)
- PC9030 Advanced PVD Grade: Features a high-toughness carbide substrate combined with a specialized nano-PVD coating designed to resist adhesive wear and thermal shock during stainless steel cutting.
- M-Type Chipbreaker Geometry (-M): Engineered with a medium-duty groove form that promotes clean chip curling, reducing cutting forces and preventing stringy chip entanglement.
- Double-Ended Economy (MGMN): Dual cutting edges double the utility per insert, delivering maximum cost efficiency for production turning environments.
- Secure Clamping Stability: Designed for precise seating in standard tool blocks to eliminate micro-vibrations and chatter during deep parting 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.
