The Original Korloy MGMN400-02-L PC5300 is a high-performance 4.0mm Double-Ended Profiling and Grooving Insert. Engineered with a sharp 0.2mm corner radius (R0.2) and the specialized -L lead geometry, this insert is the professional’s choice for precision contouring, finishing of deep grooves, and intricate parting-off operations on medium-to-large components. The PC5300 PVD grade provides an elite combination of heat resistance and substrate toughness, ensuring stable performance across a vast range of industrial materials.
The Precision Powerhouse: While 4.0mm inserts are typically used for heavy metal removal, the MGMN400-02-L is specifically designed to handle lateral cutting forces for profiling. This allows for creating complex shapes and tapered shoulders in 4.0mm applications without sacrificing dimensional accuracy.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN400-02-L |
| Insert Width / Radius | 4.0 mm / R0.2 |
| Grade | PC5300 (Universal High-Toughness PVD) |
| Operation | Profiling, Finishing, Precise Radial Grooving |
Core Performance Benefits:
- Sharper Precision: The R0.2 radius allows for sharp corners and precise detail work even at a 4.0mm width.
- Universal Grade Excellence: PC5300 grade is optimized for reliability in Steel (P), Stainless Steel (M), and Heat Resistant Alloys (S).
- Optimized Lateral Control: The -L geometry is specifically engineered to reduce tool deflection during "side-turning" or profiling.
- Premium PVD Coating: TiAlN-based coating provides excellent protection against crater wear and built-up edge.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Mild / Carbon Steel | 110 - 180 m/min | 0.05 - 0.14 mm/rev |
| Stainless Steel (304/316) | 80 - 130 m/min | 0.04 - 0.12 mm/rev |
| Alloy Steel (Pre-hardened) | 70 - 140 m/min | 0.05 - 0.11 mm/rev |
Compatible Tool Holders:
Universal 4.0mm seat size. Pairs perfectly with high-stability holders:
- External Holders: MGEHR 2020-4 / 2525-4 / 3232-4
- Internal Holders: MGIVR 2520-4 / 3125-4
Profiling Selection: MGMN400-02-L vs. Standard MGMN400-M
Understanding the difference between profiling and plunging geometries:
The Finisher. Designed for sideways movement. The R0.2 radius and special edge prep are engineered to prevent vibration during complex contouring.
The Plunger. Best for straight-down grooving and parting. It may produce vibration or "chatter" marks if used for heavy lateral profiling.
Machinist's Pro Tip: For MGMN400-02-L PC5300, always ensure your machine's spindle rigidity is high. At 4.0mm wide, lateral profiling generates significant side-pressure; a sturdy 2525 or 3232 holder is recommended for the best results.
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.
