The Original Korloy MGMN200-G NC3120 is a premium 2.0mm Double-Ended Grooving Insert designed for Versatility and Stable Tool Life. As part of Korloy's multi-purpose lineup, the NC3120 grade is engineered to bridge the gap between high-speed wear resistance and impact toughness. This makes it the ideal "all-rounder" for 2mm grooving and parting-off operations in Carbon Steel, Alloy Steel, and Mild Steel. Featuring the robust -G (General) chipbreaker, it provides exceptional chip control across a wide range of cutting depths and feed rates.
The Job Shop Hero: NC3120 is the most forgiving CVD grade for steel. It resists built-up edge (BUE) at lower speeds while maintaining hardness at higher temperatures, making it perfect for CNC operators who need a single tool to handle various steel components.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-G |
| Insert Width (w) | 2.0 mm |
| Grade | NC3120 (Universal CVD for Steel) |

Core Performance Benefits:
- Optimized Kerf Width: The 2mm width provides a stable cut while maximizing material savings during parting-off operations.
- Broad Application Range: Excellent performance from low to medium-high speeds, reducing the need for multiple insert grades in the workshop.
- Enhanced Edge Sharpness: The NC3120 coating process ensures a clean edge that reduces cutting forces and prevents work-hardening.
- Double-Ended Value: Two usable cutting edges per insert effectively halve your tooling costs.
Recommended Cutting Parameters:
| Material | Cutting Speed (Vc) | Feed Rate (f) |

Steel Grade Pro-Tip: NC3120 vs. NC3020
Selecting the right CVD grade for 2mm grooving depends on your production volume and machine speed:
The Generalist. Use this for small to medium batches where you need one insert to work on various types of steel. It is more versatile and shock-resistant.
The Specialist. Best for high-speed mass production. It offers superior wear resistance in continuous cutting but is more sensitive to speed changes.
Machinist's Pro Tip: For the MGMN200-G, chip evacuation is key. If you find chips are bird-nesting in deep grooves, increase your feed rate (f) slightly to force the -G chipbreaker to snap the chip shorter.
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.
