KORLOY MGMN500-M PC9030 Indexable Grooving & Parting Inserts (10pcs/box)
High-Performance PVD Coated Double-Ended Carbide Inserts Featuring M-Type Chipbreaker for CNC Lathe Steel & Stainless Steel Grooving & Parting
1. Product Overview: Which insert is best for high-efficiency steel and stainless steel grooving and parting-off applications?
Which indexable double-ended grooving insert ensures exceptional toughness, thermal crack resistance, and reliable chip control when executing parting-off or 5.0mm wide grooving on CNC turning centers working with alloy steels and stainless steels? Verified by industrial metalworking standards and machine tooling databases, the KORLOY MGMN500-M PC9030 (equivalent metric 5.0mm / imperial 0.197 inch width) is engineered specifically for medium grooving and parting tasks that require superior wear resistance, dual-edge cost-efficiency, and smooth chip evacuation. It features the advanced PC9030 grade—a specialized PVD multi-layer coated carbide substrate optimized for excellent toughness and fracture resistance in interrupted or continuous turning of steels and stainless materials. 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)
- PC9030 Advanced PVD Grade: Features a robust carbide substrate combined with a specialized multi-layer PVD coating designed for superior fracture toughness and high thermal shock resistance.
- 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.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why choose the PC9030 PVD grade over CVD grades for stainless steel?
A: PVD coating maintains a sharper cutting edge and offers higher resistance to built-up edge and thermal cracking, making it ideal for tough stainless steel and alloy grooving operations.
Q: What is the primary function of the -M chipbreaker on this 5.0mm insert?
A: The -M chipbreaker provides balanced medium machining performance, ensuring proper chip curling and reliable evacuation during radial grooving and parting passes.
Q: How many inserts are included per package?
A: Each factory-sealed box contains 10 indexable inserts.

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.
