Korloy MRMN200-M NC3020 2mm Full Radius R1.0 Steel Profiling Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MRMN200-M NC3020 is a precision 2.0mm Full Radius (R1.0) Profiling Insert specifically engineered for high-efficiency Steel (P) machining. Featuring the advanced NC3020 CVD coating, this insert excels in continuous, high-speed turning environments. The Full Radius (Round Nose) design combined with the -M chipbreaker provides excellent chip control and prevents vibration during intricate 3D contouring, making it an essential tool for hydraulic components, mold-making, and specialized automotive parts.
The Steel Profiling Specialist: NC3020 is designed for stability. Its smooth CVD surface effectively resists crater wear and thermal cracking, allowing you to push cutting speeds significantly higher than PVD grades when machining carbon and alloy steels.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MRMN200-M |
| Insert Shape | Full Radius (Round Nose) |
| Width / Radius | 2.0 mm / R1.0 |

Core Performance Benefits:
- Full Radius (R1.0) Versatility: Ideal for half-round grooves and smooth multi-axis contouring without leaving "step" marks.
- Premium CVD Wear Resistance: Thick-layer coating technology ensures longer tool life during high-temp continuous cutting.
- Optimized -M Chipbreaker: Designed for stable chip evacuation across a wide range of feed rates in steel materials.
- Superior Surface Finish: Low-friction coating minimizes built-up edge, delivering a mirror-like finish on shafts and profiles.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|

Machinist Tip: NC3020 vs. PC5300 for Full Radius
When choosing MRMN200 full radius inserts, consider your machining environment:
The High-Volume Specialist. Best for continuous, high-speed turning in steel. CVD coating offers superior heat resistance and much longer tool life in stable setups.
The Tough Versatile. Choose this for interrupted cuts, stainless steel, or when your machine setup isn't perfectly rigid. PVD is tougher but wears faster at high speeds.
Pro Advice: Because MRMN200-M NC3020 uses a full radius, the cutting force changes as the tool moves along the curve. Always maintain a consistent feed rate to prevent work-hardening and to fully utilize the CVD coating's thermal protection.
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.
