Korloy MGMN200-G NC3030 2mm Double-Ended Tough Grooving Insert for Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN200-G NC3030 is a high-performance 2.0mm Double-Ended Grooving Insert specifically engineered for Maximum Toughness and Reliability. While most inserts struggle with vibrations or interrupted surfaces, the MGMN200-G combined with the NC3030 CVD grade thrives in the toughest environments. It is the industry-standard choice for parting-off hex bars, machining components with cross-holes, or grooving forged steel parts with uneven surfaces.
Interruption Specialist: The NC3030 grade features a specialized high-toughness substrate and a shock-resistant CVD coating. This "safety-first" design prevents catastrophic tool failure during non-continuous cuts, ensuring your machine keeps running smoothly.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-G |
| Width (w) | 2.0 mm |
| Grade | NC3030 (High-Toughness CVD) |
| Chipbreaker | -G (Reinforced Edge) |
Core Performance Benefits:
- Superior Shock Resistance: Engineered to withstand heavy impacts during interrupted cutting cycles in carbon and alloy steels.
- Reinforced Rake Angle: The -G geometry provides a stronger cutting edge compared to -M or -H, reducing the risk of micro-chipping.
- Double-Ended Economy: Two sharp edges per insert provide a cost-effective solution for roughing and parting-off.
- Thermal Stability: The CVD coating acts as a heat barrier, protecting the carbide core during heavy-duty dry machining.
Recommended Cutting Parameters:
| Workpiece Condition | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Carbon Steel (General) | 110 - 180 m/min | 0.05 - 0.15 mm/rev |
| Interrupted Cut (Hex/Gear) | 80 - 140 m/min | 0.05 - 0.12 mm/rev |
| Alloy Steel / Forgings | 90 - 160 m/min | 0.05 - 0.13 mm/rev |

Strategic Guide: NC3030 vs. NC3020
Both are CVD grades for steel, but they serve different production goals:
The Toughness Choice. Best for interrupted cuts, low-to-medium speeds, and unstable conditions. It prevents chipping and breakage.
The Wear Choice. Best for high-speed, continuous cutting. It offers longer tool life if the machining setup is perfectly stable.
Machinist's Pro Tip: If you are experiencing premature tool failure or "snapping" during the final stage of parting-off, switch to MGMN200-G NC3030. The added toughness often solves the problem where harder grades fail.
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.
