Korloy MGMN200-02-L PC5300 2mm Precision Profiling & Grooving Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN200-02-L PC5300 is a specialized 2.0mm Precision Profiling and Grooving Insert. Featuring a 0.2mm corner radius (R0.2) and the -L optimized lead geometry, this insert is designed for machinists who require superior surface finishes and tight tolerances in narrow grooving and profiling applications. Powered by the PC5300 universal PVD grade, it offers the perfect balance of edge sharpness and thermal stability for small-to-medium component manufacturing.
The Finishing Specialist: The "L" geometry is tailored to reduce cutting forces and improve chip control during delicate profiling maneuvers. Combined with the 2.0mm width, it allows for intricate detailing on workpieces while maintaining the structural integrity of the tool.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-02-L |
| Width / Radius | 2.0 mm / R0.2 |
| Grade | PC5300 (Universal High-Toughness PVD) |

Core Performance Benefits:
- Enhanced Surface Finish: The R0.2 corner radius and polished-like PVD coating deliver exceptional part aesthetics.
- Optimized Chip Control: The -L lead geometry effectively manages chips even at low feed rates, preventing workpiece scratching.
- Universal Compatibility: PC5300 grade performs reliably across Steel (P), Stainless Steel (M), and Heat-Resistant Alloys (S).
- Narrow Profile Rigidity: Despite its 2.0mm width, the insert design minimizes deflection during lateral profiling movements.

Tech Tip: Profiling with MGMN200-02-L
Precision profiling requires a different mindset than standard parting-off:
The Precision Finisher. Features a sharper, lead-oriented edge. It is superior for lateral movements and achieving high-quality surface finishes in complex profiles.
The Versatile Standard. Better suited for straight grooving and general parting where lateral profiling is minimal.
Machinist's Pro Tip: For MGMN200-02-L PC5300, when profiling stainless steel, keep your depth of cut ($ap$) consistent. The PC5300 grade loves a steady load; avoid "skimming" at extremely shallow depths to prevent work-hardening and tool rubbing.
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.
