Korloy MGMN200-G NC3020 2mm Double-Ended 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 NC3020 is a versatile 2.0mm Double-Ended Grooving Insert engineered for high-performance General Grooving and Parting-off. Featuring the NC3020 CVD-coated grade, this insert is optimized for high-speed machining in Carbon Steel and Alloy Steel. The -G (General) chipbreaker is designed with a reinforced edge and a wide chip-breaking range, making it reliable for a variety of depths and feed rates in stable cutting environments.
High-Speed Production: The NC3020 grade features a thick Al2O3 CVD coating that provides excellent heat insulation and crater wear resistance. If you are running long production cycles on steel components, this insert will maintain dimensional accuracy at higher spindle speeds (Vc).
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-G |
| Width (w) | 2.0 mm |
| Grade | NC3020 (Hard CVD for Steel) |
| Chipbreaker | -G (General Purpose) |
Core Performance Benefits:
- Universal Compatibility: The 2mm width is the "golden standard" for most small-to-medium grooving and cut-off tasks.
- Enhanced Edge Strength: The -G geometry is more robust than -M or -H, making it less prone to micro-chipping during radial plunging.
- Double-Ended Efficiency: Two usable cutting edges help halve your tooling costs per part.
- Superior Wear Resistance: The NC3020 grade thrives in continuous cutting, resisting the abrasive wear of carbon steels.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Low Carbon Steel | 140 - 240 m/min | 0.05 - 0.15 mm/rev |
| Alloy Steel | 110 - 200 m/min | 0.05 - 0.12 mm/rev |
| High Carbon Steel | 100 - 180 m/min | 0.04 - 0.10 mm/rev |
Compatible Tool Holders:
Fits all standard 2.0mm MGEHR/L grooving bars:
- External Holders: MGEHR 1212-2 / 1616-2 / 2020-2 / 2525-2
Selection Guide: NC3020 vs. NC3030
Both are CVD grades for steel, but the choice depends on your machine stability:
The Efficiency Choice. Optimized for high speeds and stable, continuous cuts. Best for maximizing tool life in long-run production.
The Toughness Choice. Ideal for interrupted cuts, rough forged surfaces, or older machines with slight vibration.
Machinist's Pro Tip: For the MGMN200-G, ensure your coolant is directed precisely at the cutting edge. 2mm grooves are narrow enough that chip packing can occur; high-pressure coolant helps eject chips and keeps the NC3020 coating from overheating.
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.
