Korloy MGMN500-M NC6210 5mm Double-Ended Cast Iron Grooving Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN500-M NC6210 is a high-performance 5.0mm Double-Ended Grooving Insert specifically engineered for Cast Iron Machining. Featuring the specialized NC6210 CVD grade, this insert is the industry standard for processing Gray Cast Iron (GG) and Ductile Iron (GGG). It utilizes an ultra-thick, heat-resistant coating that prevents the rapid abrasive wear typical of iron casting particles, ensuring stable dimensions and exceptional tool life in heavy-duty 5.0mm applications.
Cast Iron Specialist: Unlike universal grades, NC6210 is formulated to withstand the high-temperature friction and abrasive dust generated when cutting iron. At 5.0mm width, it provides the massive rigidity needed for deep grooves in heavy cast components.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN500-M |
| Insert Width (w) | 5.0 mm |
| Grade | NC6210 (High-Speed Cast Iron - CVD) |
| Target Material | Gray Cast Iron / Ductile Cast Iron (K Group) |
Core Performance Benefits:
- Maximum Abrasion Resistance: Optimized for the "sand-paper" effect of cast iron, extending life where steel grades fail.
- Heavy-Duty Stability: The 5.0mm width allows for high-pressure plunging without tool deflection or vibration.
- Thermal Protection: Thick CVD alumina layer allows for high-speed dry machining, common in cast iron production.
- Precision Chipbreaker: The -M geometry effectively manages the shorter, more brittle chips produced by iron alloys.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Gray Cast Iron (HT250/GG25) | 150 - 300 m/min | 0.15 - 0.35 mm/rev |
| Ductile Cast Iron (QT450/GGG40) | 120 - 220 m/min | 0.12 - 0.30 mm/rev |
| Malleable Cast Iron | 100 - 200 m/min | 0.12 - 0.28 mm/rev |
Compatible Tool Holders:
To support 5.0mm width cutting forces, use heavy-duty MGEHR/L holders:
- External Holders: MGEHR 2525-5 / 3232-5 / 4040-5
The Cast Iron Choice: NC6210 vs. NC3120
Using the right grade for the right material is critical for your bottom line:
The Casting Expert. Specifically for K-group materials. It handles the abrasive nature of iron far better than steel grades, doubling tool life in cast iron tasks.
The Steel Universal. While it can cut iron, it is not optimized for it. High heat and abrasion will cause the edge to dull much faster compared to NC6210.
Machinist's Pro Tip: Cast iron often has a hard "chilled" outer skin. When using the MGMN500-M NC6210, try to ensure your first plunge is deep enough to get beneath the scale, or reduce speed slightly during the initial skin break to protect the cutting edge.
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.
