Korloy MGMN400-02-R PC5300 4mm R0.2 Right-Hand Universal Profiling Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN400-02-R PC5300 is a high-rigidity 4.0mm Right-Hand Profiling and Grooving Insert. Engineered for superior versatility, this insert features the advanced PC5300 PVD coating, making it an exceptional choice for machining Stainless Steel, Alloy Steel, and Cast Iron. The precise 0.2mm corner radius (R0.2) allows for sharp detailing and tight tolerance control, even when performing heavy-duty 4.0mm wide cuts in tough materials.
The Heavy-Duty Precision Specialist: At 4.0mm wide, lateral stability is key. The PC5300 grade provides the perfect balance between a hard-wearing surface and a tough substrate, preventing edge collapse during complex profiling paths in work-hardening materials like 304/316 stainless steel.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN400-02-R |
| Insert Width / Radius | 4.0 mm / R0.2 |

Pro Tip: Why PC5300 for 4.0mm Profiling?
At 4.0mm wide, the cutting forces can be significant. Here is how PC5300 stacks up:
The Tough Finisher. Best for versatile shops. It handles the transition from grooving to side-turning better than harder grades, resisting the "notching" wear common in stainless steel.
The Steel Speedster. If you are ONLY cutting carbon steel in high volume, CVD grades like NC3030 offer higher speed, but they lack the edge toughness of PC5300 for stainless work.
Machinist's Insight: For MGMN400-02-R PC5300, the R0.2 radius is great for precision, but remember that the 4mm width generates more heat. Use plenty of coolant to maximize the PVD coating life, especially when side-turning in stainless.
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.
