Korloy MGMN400-04-R PC5300 4mm R0.4 Right-Hand Universal Tough Profiling Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN400-04-R PC5300 is a high-strength 4.0mm Right-Hand Profiling and Grooving Insert. Engineered for tough machining environments, this insert features the renowned PC5300 universal PVD coating, making it a powerhouse for Stainless Steel (M), Carbon Steel (P), and Heat-Resistant Alloys (S). The reinforced 0.4mm corner radius (R0.4) provides the extra edge security needed for higher feed rates and more aggressive side-turning (profiling) in large-diameter workpieces.
Maximum Stability for Heavy Cuts: The MGMN400-04-R is the "Heavy Duty" version of our 4.0mm profiling series. The R0.4 radius redistributes cutting pressure across a wider surface, significantly reducing the risk of edge chipping when machining scaly materials or performing interrupted cuts in stainless steel.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN400-04-R |
| Insert Width / Radius | 4.0 mm / R0.4 |
| Direction | Right-Hand (-R) |
| Grade | PC5300 (Universal High-Toughness PVD) |
Core Performance Benefits:
- Reinforced Corner Geometry: The R0.4 radius allows for up to 30% higher feed rates compared to the R0.2 model without sacrificing edge life.
- PVD Multi-Layer Technology: High-Al TiAlN coating provides an excellent thermal barrier and prevents built-up edge (BUE) in gummy materials.
- Universal Compatibility: One insert for multiple material groups, reducing inventory costs and setup times.
- Superior Vibration Resistance: Designed to maintain a stable cut even at high depths of cut (DOC) during lateral turning.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Stainless Steel (316/304) | 70 - 130 m/min | 0.08 - 0.18 mm/rev |
| Alloy Steel (42CrMo) | 90 - 170 m/min | 0.10 - 0.22 mm/rev |
| Ductile Iron (FCD) | 80 - 160 m/min | 0.12 - 0.25 mm/rev |
Compatible Tool Holders:
Precision fit for all standard 4.0mm seat Right-Hand systems:

- Internal Holders: MGIVR 3125-4 / 4032-4
Tech Tip: Choosing the Right 4mm Radius
Optimizing your 4.0mm PC5300 insert selection for better efficiency:
The Productivity Master. Best for semi-finishing and roughing where you need to move fast. It is more durable during interrupted cuts and handles heavy alloy steel better.
The Detail Master. Best for final finishing and sharp corner profiling. It generates lower cutting forces but is more susceptible to chipping at high feeds.
Machinist's Pro Advice: For MGMN400-04-R PC5300, ensure your coolant is directed at both the flank and the top face. This model thrives when the larger radius is allowed to "bite" into the material—if your feed is too low, you may experience work-hardening in stainless steel.
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.
