Kennametal KSEM vs Guhring RT 100 U
Kennametal KSEM and Guhring RT 100 U 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 U is a coolant-through carbide drill platform with distinct depth and shank series.
Side-by-side comparison
| Category | Kennametal KSEM | Guhring RT 100 U |
|---|---|---|
| System architecture | System architecture: machine-side drill body plus workpiece-side KSEM center insert, with compatibility controlled by diameter and insert seat size. | Series 5610 is a 3xD nano-FIREX, 140-degree RT 100 U with coolant and HE shank. |
| Documented application focus | Modular production drilling where a reusable body and replaceable carbide cutting point are preferred. | Production drilling in the material groups available for the exact RT 100 U item. |
| 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. | Series 5511 is the 5xD nano-FIREX, 140-degree HA-shank branch. |
| 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. | Depth, shank, coating, margin design, diameter, and EDP identity control compatibility. |
| 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, code, EDP, diameter, L/D, shank, coating, point, margin form, coolant, and current cutting-data source. |
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 U
- Production drilling in the material groups available for the exact RT 100 U item.
- Store series, code, EDP, diameter, L/D, shank, coating, point, margin form, coolant, and current cutting-data source.
Selection notes
Use KSEM when its documented application focus and technical configuration match the operation more closely; use RT 100 U 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 U: Depth, shank, coating, margin design, diameter, and EDP identity control compatibility.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
