ISCAR SUMOCHAM vs Guhring RT 100 FB
ISCAR SUMOCHAM and Guhring RT 100 FB are documented holemaking systems with different product architecture and application priorities. ISCAR SUMOCHAM is an exchangeable solid-carbide drilling-head system built around reusable drill bodies, replaceable heads, internal coolant, and application-specific head geometries and grades. Guhring RT 100 FB Series 6596 is a two-flute, coolant-through flat-bottom carbide drill.
Side-by-side comparison
| Category | ISCAR SUMOCHAM | Guhring RT 100 FB |
|---|---|---|
| System architecture | ISCAR describes exchangeable solid-carbide heads mounted in steel drill bodies with internal coolant delivery. | Series 6596 is approximately 3xD with a 180-degree point. |
| Documented application focus | Production drilling where worn heads can be changed without replacing the drill body. | Flat-bottom holes and low-burr exits. |
| Technical selection detail | SUMOCHAM ranges include multiple L/D series, head geometries, grades, and body configurations. | It uses carbide, nano-FIREX coating, internal coolant, and an HA shank. |
| Primary documented constraint | Head diameter alone does not establish pocket, body, grade, geometry, or drilling-depth compatibility. | Series 6596 and micro Series 6496 are not interchangeable. |
| Manufacturer-guided selection | Store drill body and head as separate products joined by an evidence-backed compatibility record, including diameter, L/D, material group, coolant, and connection. | Store series, EDP, code, diameter, L/D, point, shank, coating, coolant, and catalog revision. |
Best fit by application
ISCAR SUMOCHAM
- Production drilling where worn heads can be changed without replacing the drill body.
- Store drill body and head as separate products joined by an evidence-backed compatibility record, including diameter, L/D, material group, coolant, and connection.
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 SUMOCHAM 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
- SUMOCHAM: Head diameter alone does not establish pocket, body, grade, geometry, or drilling-depth compatibility.
- 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.
