Korloy RPMW1003MO KF2500 10mm Round Milling Insert for Cast Iron (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy RPMW1003MO KF2500 is a specialized 10.0mm Round (RPMW) Milling Insert, specifically engineered for high-stability machining of Cast Iron (K Group). Utilizing the advanced KF2500 Grade, this insert features a high-density substrate that provides the perfect balance of hardness and toughness. It is the premier choice for face milling and copy milling of engine blocks, industrial machine bases, and any component made from grey or ductile iron.
Optimized for Cast Iron: Cast iron machining is characterized by abrasive wear. The KF2500 grade is formulated with superior flank wear resistance, ensuring that the 10mm round edge maintains its profile even in prolonged high-speed milling cycles.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | RPMW1003MO |
| Insert Shape | Round (RP) |
| Diameter / Thickness | 10.0 mm / 3.18 mm |
| Grade | KF2500 (Cast Iron Specialist) |
Core Performance Benefits:
- High Flank Wear Resistance: Specifically resists the abrasive particles found in cast iron, significantly extending tool life compared to universal grades.
- Impact Toughness: The KF2500 substrate is designed to handle the heavy-interrupted cuts typical of large cast iron workpieces with sand holes or surface skin.
- Precision Ground Edge: The RPMW geometry ensures a stable seat in the tool holder, minimizing runout during heavy roughing.
- Superior Heat Dispersion: Engineered to manage the thermal loads of dry-cutting cast iron.
Recommended Cutting Parameters (Cast Iron):
| Material Group | Cutting Speed (Vc) | Feed per Tooth (fz) |

Machinist Tip: Why KF2500 for Iron?
In cast iron milling, the abrasive content can destroy general-purpose coatings. Here is why KF2500 stands out:
Abrasive Resistance. Specifically tuned to handle the graphite and silicon content in cast iron. It resists the "micro-chipping" of the edge that often occurs with universal grades in iron applications.
The Generalists. While PC5300 can cut iron, it is optimized for steel's ductility. In high-volume iron production, PC5300 will wear faster than the dedicated KF2500.
Pro Advice: For RPMW1003MO KF2500, dry machining is often preferred for grey cast iron to avoid thermal cracking of the insert. Ensure good chip evacuation to prevent re-cutting of iron dust, which can act as an abrasive and shorten tool life.
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.
