KORLOY MGMN500-04-R PC5300 Indexable Grooving & Parting Inserts (10pcs/box)
High-Durability PVD Coated Double-Ended Carbide Inserts for CNC Lathe Steel and Stainless Steel Grooving, Parting-Off, and Radius Profiling
1. Product Overview: Which insert is best for high-efficiency steel and stainless steel double-ended grooving and parting applications?
Which indexable double-ended grooving insert ensures exceptional wear resistance, thermal shock stability, and reliable chip control when executing precision parting-off, radius profiling, or 5.0mm grooving on CNC turning centers working with alloy steels and stainless steels? Verified by industrial metalworking standards, the KORLOY MGMN500-04-R PC5300 is engineered specifically for demanding metalcutting tasks that require superior fracture toughness, dual-edge cost-efficiency, and smooth chip evacuation. It features the advanced PC5300 grade—a specialized PVD multi-layer coated carbide substrate optimized for high resistance to built-up edge and thermal cracking under continuous or interrupted cutting conditions. Combined with its precision right-hand (-R) geometry and optimized corner radius, it controls chip formation and reduces cutting forces during radial and axial feeds.
2. Product Core Advantages (Key Features)
- PC5300 Advanced PVD Grade: Features a high-toughness carbide substrate with a smooth PVD coating designed to minimize friction and resist flank wear in steel and stainless steel turning.
- Double-Ended Efficiency (MGMN): Dual-sided cutting edges maximize tooling economy by allowing indexability to a fresh edge once the first side wears.
- 0.4mm Corner Radius (-04-R): Engineered with a precise 0.4mm corner radius profile to strengthen the cutting edge and improve surface finish during profile turning and corner stress distribution.
- Rigid Central Clamping Interface: Provides high clamping stability and precise seating to eliminate micro-vibrations during heavy parting passes.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: What is the advantage of the 0.4mm corner radius on the MGMN500-04-R insert?
A: The 0.4mm corner radius provides added edge strength compared to sharp corners, helping to prevent chipping during profile turning and improving the final surface finish of the machined groove floor.
Q: How should feed rate be managed during deep parting with a 5.0mm wide insert?
A: It is recommended to reduce the feed rate by 30% to 40% when approaching the center axis to minimize cutting resistance and prevent mechanical shock.
Q: How many inserts are included in each factory package?
A: Each 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.
