The Original Korloy MGMN500-04-R PC5300 is a heavy-duty 5.0mm Right-Hand Profiling and Grooving Insert engineered for maximum material removal and stability. Featuring a reinforced 0.4mm corner radius (R0.4) and Korloy’s premium PC5300 PVD coating, this insert is the premier choice for machining large-scale components in Stainless Steel, Carbon Steel, and Cast Iron. The 5mm width ensures extreme rigidity, allowing for deeper cuts and more aggressive lateral profiling in challenging industrial applications.
Power and Precision in 5.0mm: When narrow inserts fail under pressure, the MGMN500-04-R excels. Its massive cross-section absorbs vibration, while the R0.4 radius provides the edge security needed for heavy feed profiling of tough alloy steels and work-hardening stainless steels.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN500-04-R |
| Insert Width / Radius | 5.0 mm / R0.4 |
| Direction | Right-Hand (-R) |
| Grade | PC5300 (Universal High-Toughness PVD) |
Core Performance Benefits:
- Maximum Rigidness: The 5.0mm body width minimizes tool deflection during high-torque grooving.
- Universal Grade Reliability: PC5300's TiAlN multi-layer coating provides a powerful thermal barrier across diverse materials.
- Optimized Lead Control: The right-hand (-R) orientation is crucial for specific side-turning paths on sub-spindle CNC machines.
- Edge Security: The R0.4 radius enhances the chipbreaker's performance, effectively controlling chips even at higher feed rates.
Recommended Cutting Parameters:

Industrial Tip: The Strength of 5.0mm R0.4
In heavy-duty applications, the radius choice is the difference between tool life and tool failure:
The Heavy-Duty Pro. Provides a larger contact area for heat dissipation. Crucial for heavy profiling of large alloy shafts where the tool is engaged for long durations.
Reliability First. 5mm grooves often face chip evacuation issues. PC5300’s tough substrate prevents the catastrophic failure that harder CVD grades might face if a chip is re-cut.
Machinist's Pro Tip: For MGMN500-04-R PC5300, ensure your machine has high-pressure coolant if possible. When grooving 5mm wide, chip crowding can happen fast—consistent pressure helps eject these larger chips and protects the R0.4 edge.
Packaging: 10 pieces per box.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
