The Original Korloy MGMN600-M NC6210 is a heavy-duty 6.0mm Double-Ended Grooving Insert engineered specifically for Heavy Cast Iron Machining. When processing large cast components, abrasive wear is the primary enemy of tool life. The NC6210 CVD grade features a specialized multi-layer coating with a reinforced alumina (Al2O3) barrier, designed to withstand the high-temperature friction of gray and ductile iron. This 6.0mm insert offers maximum rigidity for deep radial plunging in the most demanding industrial environments.
Maximum Material Removal: At 6.0mm wide, the MGMN600-M provides the structural strength required for aggressive cuts in large-scale castings. The NC6210 grade ensures the edge remains sharp even when facing the "sand-paper" effect of iron casting surfaces.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN600-M |
| Insert Width (w) | 6.0 mm (+/- 0.05) |
| Grade | NC6210 (Cast Iron Specialist - CVD) |
| Ideal For | Gray Iron (GG), Ductile Iron (GGG), Malleable Iron |
Core Performance Benefits:
- Engineered for Abrasion: Specialized coating protects the carbide substrate from the abrasive particles found in castings.
- 6.0mm High Stability: Massive tool body resists deflection during high-torque parting of large shafts.
- Thermal Shield: Optimized for high-speed dry machining, reducing thermal shock and micro-cracking.
- Heavy Chip Management: The -M geometry effectively rolls and breaks wide, brittle iron chips for clean evacuation.
Recommended Cutting Parameters:
| Cast Iron Type | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|

Cast Iron Expert Tip: NC6210 vs. Steel Grades
Why a specialized grade matters for 6.0mm grooving:
The Cast Iron Pro. Optimized for abrasion resistance. It will far outlast any steel grade in iron, preventing the rapid rounding of the cutting edge.
The Steel Generalists. While excellent for P-group materials, they will wear prematurely in cast iron due to chemical and abrasive incompatibility.
Machinist's Pro Tip: For MGMN600-M NC6210, if you encounter surface "crusting" or vibration on large diameter parts, try a "peck-grooving" cycle. This helps manage the massive heat generated by the 6.0mm wide contact area and allows the specialized NC6210 coating to reset its thermal load.
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.
