The Original Korloy MGMN200-M PC215K is a precision 2.0mm Double-Ended Grooving Insert specifically engineered for High-Performance Cast Iron Machining. Utilizing the advanced PC215K PVD grade, this insert provides the ultimate solution for processing Gray Cast Iron (GG) and Ductile Iron (GGG) where precision and edge toughness are paramount. Its fine-grained carbide substrate and specialized coating prevent micro-chipping, ensuring consistent dimensions in high-speed CNC environments.
Precision for Iron Castings: At 2.0mm width, the MGMN200-M reduces material waste while the PC215K grade tackles the abrasive nature of iron. It is particularly effective for small to medium-sized cast components requiring high surface quality.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-M |
| Insert Width (w) | 2.0 mm |
| Grade | PC215K (Fine-Grain Cast Iron Specialist - PVD) |
| Chipbreaker | -M (Universal Geometry for Stability) |
Core Performance Benefits:
- Edge Chipping Resistance: Specialized PVD coating prevents the "peeling" effect common in cast iron machining.
- Narrow Kerf Advantage: 2.0mm width minimizes tool pressure and saves expensive raw material during parting.
- Thermal Shock Stability: Excellent performance in both dry and wet machining of iron alloys.
- High Surface Finish: The -M geometry and sharp edge of the PC215K grade provide superior finishes on brittle materials.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Gray Cast Iron (HT250/GG25) | 120 - 220 m/min | 0.05 - 0.15 mm/rev |
| Ductile Iron (QT450/GGG40) | 100 - 180 m/min | 0.05 - 0.12 mm/rev |
| Malleable Iron | 90 - 160 m/min | 0.06 - 0.14 mm/rev |

Cast Iron Grade Choice: PC215K vs. NC6210
Korloy offers two main paths for Cast Iron (K-Group) machining:
The Precision Specialist. A PVD grade that is sharper and tougher. Ideal for 2.0mm - 3.0mm width grooving where edge stability and high-quality finish are required.
The High-Speed Giant. A CVD grade with ultra-thick coating. Better for heavy-duty roughing and 5.0mm+ widths where maximum wear resistance at high speeds is needed.
Machinist's Pro Tip: For MGMN200-M PC215K, avoid excessive vibration. Because cast iron produces dusty, short chips, ensure your tool path allows for consistent contact. If the iron is "chilled" (extra hard surface), reduce the entry speed slightly to preserve the PVD coating.
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.
