Korloy RPMT1204MO-Q KF5800 12mm Round Milling Insert for Titanium & Super Alloys (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy RPMT1204MO-Q KF5800 is the ultimate 12.0mm Round (RPMT) Milling Insert designed for high-performance machining of Titanium Alloys and Heat-Resistant Super Alloys (HRSA). As the largest standard size in the series, it is engineered for heavy material removal in components such as aircraft engine casings and structural frames. The KF5800 Grade is a sub-micron carbide powerhouse, offering extreme red-hardness to withstand the 1000°C+ temperatures generated when cutting Nickel-based superalloys.
Heavy-Duty Thermal Management: Machining S-group materials at scale requires maximum insert mass. The 12mm RPMT1204 body acts as a massive heat sink, while the KF5800 grade maintains a razor-sharp edge even under the intense thermal loads typical of Inconel roughing.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | RPMT1204MO-Q |
| Insert Shape | Round (RP) |
| Diameter / Thickness | 12.0 mm / 4.76 mm |
| Grade | KF5800 (Advanced HRSA/Titanium Grade) |
Core Performance Benefits:
- Exceptional Red-Hardness: The KF5800 substrate is chemically stable at extreme temperatures, preventing edge deformation in Cobalt and Nickel alloys.
- Optimized Round Strength: 12mm diameter provides the highest level of pocket security for heavy roughing and large-scale profiling.
- Reduced Cutting Forces: The -Q geometry features an aggressive rake angle that shears through tough skins without work-hardening the base material.
- Aerospace Reliability: Predictable wear patterns allow for precise calculation of tool changes in expensive, mission-critical workpieces.
Recommended Cutting Parameters (S Group):

Machinist Tip: The Power of 12mm KF5800
When roughing Titanium and Super Alloys, tool diameter and grade synergy is everything:
Uncoated Excellence. In high-temp alloy milling, coatings can sometimes delaminate and cause catastrophic failure. KF5800 uses a high-purity sub-micron substrate that performs exceptionally well "naked" against Titanium's chemical affinity.
The 12mm round shape allows you to use very high feed rates due to chip thinning. In Titanium, this keeps the heat in the chip and away from the workpiece, extending the life of your expensive tooling.
Pro Advice: For RPMT1204MO-Q KF5800, ensure your milling machine has high spindle torque. When utilizing the full 12mm radius in Inconel, the radial forces are immense. Always use through-spindle coolant to flush chips and provide maximum lubrication.
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.
