Korloy MGMN200-04-R PC5300 2mm R0.4 Right-Hand Tough Profiling Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN200-04-R PC5300 is a specialized 2.0mm Right-Hand Profiling Insert designed for maximum edge strength in narrow applications. Unlike standard 2mm inserts, this model features a reinforced 0.4mm corner radius (R0.4), which allows for significantly higher feed rates and better heat dissipation during lateral turning. Powered by the PC5300 universal PVD grade, it provides unmatched reliability when profiling Stainless Steel, Carbon Steel, and Alloy Steels in high-precision CNC operations.
The "Narrow Workhorse": The MGMN200-04-R is the perfect solution when you need to perform aggressive profiling or contouring within a 2.0mm groove. The larger R0.4 radius strengthens the weakest point of the insert, making it highly resistant to chipping under heavy side-loading.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-04-R |
| Insert Width / Radius | 2.0 mm / R0.4 |
| Direction | Right-Hand (-R) |
| Grade | PC5300 (Universal High-Toughness PVD) |
Core Performance Benefits:
- Maximum Edge Toughness: The R0.4 radius redistributes cutting forces, allowing the 2mm insert to handle much tougher materials without edge failure.
- High Feed Profiling: Specifically designed for lateral movement; the larger radius enables faster cycle times in semi-finishing operations.
- Universal Material Range: PC5300 grade excels across P (Steel), M (Stainless), and K (Cast Iron), reducing the need for multiple insert types.
- Advanced PVD Coating: TiAlN-based coating provides a smooth surface to resist built-up edge and thermal shock.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Alloy Steel (4140/42CrMo) | 100 - 180 m/min | 0.05 - 0.12 mm/rev |
| Stainless Steel (316/304) | 80 - 140 m/min | 0.04 - 0.10 mm/rev |
| Pre-hardened Steel | 60 - 120 m/min | 0.03 - 0.08 mm/rev |

Machinist Tip: Why R0.4 on a 2mm Insert?
The choice between R0.2 and R0.4 on a 2.0mm body significantly impacts your process:
The Tough Choice. Best for profiling with higher lateral forces. It dissipates heat better and is less likely to break when hitting hard spots in the material.
The Precision Choice. Best for getting into sharp corners. However, the tip is much more fragile and requires conservative feeds to avoid chipping.
Pro Advice: For MGMN200-04-R PC5300, ensure your machine spindle is running true. Even with a reinforced R0.4 radius, 2mm inserts are sensitive to run-out. Use the larger radius to your advantage by increasing feed rates by 15-20% over standard R0.2 settings.
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.
