Kennametal KSEM vs Guhring RT 100 FB
Kennametal KSEM and Guhring RT 100 FB are documented holemaking systems with different product architecture and application priorities. KSEM is Kennametal's modular drilling system built around reusable drill bodies and replaceable carbide center inserts. Guhring RT 100 FB Series 6596 is a two-flute, coolant-through flat-bottom carbide drill.
Side-by-side comparison
| Category | Kennametal KSEM | Guhring RT 100 FB |
|---|---|---|
| System architecture | System architecture: machine-side drill body plus workpiece-side KSEM center insert, with compatibility controlled by diameter and insert seat size. | Series 6596 is approximately 3xD with a 180-degree point. |
| Documented application focus | Modular production drilling where a reusable body and replaceable carbide cutting point are preferred. | Flat-bottom holes and low-burr exits. |
| Technical selection detail | Official records identify bodies by depth ratio and shank style, including WN, WD, SS, SSF, and structural-steel SFP variants across the available range. | It uses carbide, nano-FIREX coating, internal coolant, and an HA shank. |
| Primary documented constraint | A body and insert with similar nominal diameters are not necessarily compatible; insert seat size and current compatibility data control the assembly. | Series 6596 and micro Series 6496 are not interchangeable. |
| Manufacturer-guided selection | Capture both Kennametal material numbers and ISO/ANSI catalog IDs for the body and insert, plus depth ratio, shank, seat size, geometry, grade, and diameter. | Store series, EDP, code, diameter, L/D, point, shank, coating, coolant, and catalog revision. |
Best fit by application
Kennametal KSEM
- Modular production drilling where a reusable body and replaceable carbide cutting point are preferred.
- Capture both Kennametal material numbers and ISO/ANSI catalog IDs for the body and insert, plus depth ratio, shank, seat size, geometry, grade, and diameter.
Guhring RT 100 FB
- Flat-bottom holes and low-burr exits.
- Store series, EDP, code, diameter, L/D, point, shank, coating, coolant, and catalog revision.
Selection notes
Use KSEM when its documented application focus and technical configuration match the operation more closely; use RT 100 FB 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
- KSEM: A body and insert with similar nominal diameters are not necessarily compatible; insert seat size and current compatibility data control the assembly.
- RT 100 FB: Series 6596 and micro Series 6496 are not interchangeable.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
