Kennametal HARVI I TE vs Guhring RF 100 Diver
Kennametal HARVI I TE and Guhring RF 100 Diver are documented milling systems with different product architecture and application priorities. HARVI I TE is Kennametal's four-flute solid-carbide end-mill family for roughing and finishing across broad material and operation coverage. Guhring RF 100 Diver is a multi-application solid-carbide end-mill family built for ramping, drilling, slotting, roughing, and finishing.
Side-by-side comparison
| Category | Kennametal HARVI I TE | Guhring RF 100 Diver |
|---|---|---|
| System architecture | The core family uses four flutes with asymmetric divided flutes, variable helix, twisted end-face geometry, relief features, and chip gashes described on official item pages. | Official Series 6798 is a three-flute carbide RF 100 Diver with center cutting, a special drill face, Signum coating, and 41/43/45-degree unequal helix. |
| Documented application focus | Roughing and finishing with one four-flute solid-carbide family across steels, stainless steels, cast irons, high-temperature alloys, and selected hardened materials. | Ramping, helical entry, plunging, slotting, roughing, and finishing with one family. |
| Technical selection detail | End forms include square, radiused, chamfered, and ball nose with regular, short, long, and necked variants. | Series 6736 is a four-flute metric carbide family with center cutting, neck clearance, Signum nano-Si coating, right-hand cutting, HB Weldon-flat shank, and 36/37/38-degree unequal helix. |
| Primary documented constraint | The HARVI name spans several distinct families; flute count, end form, grade, diameter, reach, and shank must be exact before comparing performance. | RF 100 Diver is not one interchangeable item; verify series, EDP number, diameter, flute count, corner geometry, reach, coating, and shank. |
| Manufacturer-guided selection | Store the Kennametal material number and catalog ID with diameter, flute length, reach, end form, corner treatment, shank, grade, and holder projection. | Store Guhring series, EDP number, and code number separately, then attach the current catalog page and cutting-data document to the operational product record. |
Best fit by application
Kennametal HARVI I TE
- Roughing and finishing with one four-flute solid-carbide family across steels, stainless steels, cast irons, high-temperature alloys, and selected hardened materials.
- Store the Kennametal material number and catalog ID with diameter, flute length, reach, end form, corner treatment, shank, grade, and holder projection.
Guhring RF 100 Diver
- Ramping, helical entry, plunging, slotting, roughing, and finishing with one family.
- Store Guhring series, EDP number, and code number separately, then attach the current catalog page and cutting-data document to the operational product record.
Selection notes
Use HARVI I TE when its documented application focus and technical configuration match the operation more closely; use RF 100 Diver when its documented architecture and constraints provide the better fit.
Compare complete configured assemblies and current manufacturer data rather than treating either family name as one universal item.
Variables to validate
- HARVI I TE: The HARVI name spans several distinct families; flute count, end form, grade, diameter, reach, and shank must be exact before comparing performance.
- RF 100 Diver: RF 100 Diver is not one interchangeable item; verify series, EDP number, diameter, flute count, corner geometry, reach, coating, and shank.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
