The Original Korloy RPMW1204MO KF5800 is a heavy-duty 12.0mm Round (RPMW) Milling Insert designed to dominate the most challenging materials: Titanium Alloys and Heat-Resistant Super Alloys (HRSA). Engineered for the aerospace and power generation sectors, the KF5800 Grade features an ultra-fine sub-micron substrate with superior red-hardness. This allows the insert to maintain a stable cutting edge even under the extreme thermal loads generated by nickel-based alloys, making it ideal for large-scale profiling and high-volume metal removal.
Heavy-Duty Stability: The 12mm diameter (R6 radius) provides massive structural strength. Combined with the KF5800 grade, this insert resists plastic deformation and notch wear, which are common failure modes when machining Inconel and Titanium at high depths of cut.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | RPMW1204MO |
| Insert Shape | Round (RP) |

Core Performance Benefits:
- Superior Red-Hardness: The KF5800 substrate is designed to withstand temperatures exceeding 900°C without losing edge sharpness.
- Sub-Micron Grain Technology: Provides the high fracture toughness required for interrupted cuts in tough, work-hardening metals.
- Optimized Heat Dissipation: The 12mm mass helps dissipate heat away from the cutting zone, protecting the tool and the workpiece.
- Extended Tool Life: Specifically formulated to resist the chemical affinity between the tool and Titanium, reducing adhesive wear.
Recommended Cutting Parameters (S-Group):
| Material Group | Cutting Speed (Vc) | Feed per Tooth (fz) |
|---|---|---|
| Titanium Alloys (e.g., Ti-6Al-4V) | 35 - 70 m/min | 0.12 - 0.25 mm/t |
| Inconel 625 / 718 | 20 - 40 m/min | 0.10 - 0.20 mm/t |
| René / Cobalt Alloys | 15 - 30 m/min | 0.08 - 0.15 mm/t |

Machinist Tip: Heavy Roughing with KF5800
When utilizing the RPMW1204 in superalloys, thermal management is your top priority:
Uncoated Performance. For HRSA, PVD coatings can sometimes mask heat buildup until it's too late. KF5800's high-purity substrate is designed to be the front line, resisting chemical wear that would destroy universal grades in minutes.
The Stainless Alternative. While these are excellent for general stainless steel, they lack the specific red-hardness of KF5800. For dedicated Titanium or Inconel production, switching to KF5800 can increase tool life by up to 50%.
Pro Advice: For RPMW1204MO KF5800, ensure high-pressure through-coolant is used to flush the contact zone. Maintain a steady feed—rubbing in Titanium will cause the material to work-harden, making subsequent passes extremely difficult.
Packaging: 10 pieces per box.
