The Original Korloy MGMN200-M CN2000 is a high-precision 2.0mm Double-Ended Cermet Insert designed specifically for High-Speed Finishing of Steel and Cast Iron. Unlike standard tungsten carbide, the CN2000 Cermet grade provides exceptional chemical stability and resistance to oxidation. This results in an incredibly smooth "mirror" surface finish and prolonged dimensional accuracy. Featuring the -M (Medium/Finishing) chipbreaker, it is the perfect choice for final passes where surface integrity is paramount.
The Finishing Specialist: CN2000 Cermet has a low affinity for metal workpieces, meaning it virtually eliminates "built-up edge" (BUE). This allows for much higher cutting speeds and produces a glossier finish than any coated carbide insert can achieve.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-M |
| Insert Width (w) | 2.0 mm |
| Grade | CN2000 (Advanced Cermet) |
| Chipbreaker | -M (Precision Finishing Geometry) |
Core Performance Benefits:
- High Gloss Surface Finish: Cermet's unique composition ensures a cleaner cut, often eliminating the need for subsequent grinding or polishing.
- Excellent Wear Resistance: Ideal for long, continuous cuts at high speeds where standard inserts would degrade thermally.
- High Dimensional Stability: Maintains tolerance over long production runs due to its high hardness and low thermal expansion.
- Reduced Tool Pressure: The sharp -M geometry reduces cutting force, perfect for precision parts and small-diameter work.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |

Tech Guide: Cermet (CN2000) vs. Carbide (NC3120)
Understanding when to switch from Carbide to Cermet is key to your finishing strategy:
The Finisher. Best for high-speed, light-depth finishing passes. Offers a mirror finish but is more brittle. Avoid interrupted cuts or heavy shocks.
The Generalists. Best for roughing, general-purpose grooving, and interrupted cuts. Tougher than cermet but cannot match its high-speed surface finish.
Machinist's Pro Tip: Cermet thrives on Speed. If you use the MGMN200-M CN2000 and get a dull finish, increase your RPM. Avoid using it for heavy roughing or in setups with high vibration, as cermet is sensitive to impact.
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.
