ISCAR SUMOCHAM vs Guhring RT 100 U
ISCAR SUMOCHAM and Guhring RT 100 U 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 U is a coolant-through carbide drill platform with distinct depth and shank series.
Side-by-side comparison
| Category | ISCAR SUMOCHAM | Guhring RT 100 U |
|---|---|---|
| System architecture | ISCAR describes exchangeable solid-carbide heads mounted in steel drill bodies with internal coolant delivery. | Series 5610 is a 3xD nano-FIREX, 140-degree RT 100 U with coolant and HE shank. |
| Documented application focus | Production drilling where worn heads can be changed without replacing the drill body. | Production drilling in the material groups available for the exact RT 100 U item. |
| Technical selection detail | SUMOCHAM ranges include multiple L/D series, head geometries, grades, and body configurations. | Series 5511 is the 5xD nano-FIREX, 140-degree HA-shank branch. |
| Primary documented constraint | Head diameter alone does not establish pocket, body, grade, geometry, or drilling-depth compatibility. | Depth, shank, coating, margin design, diameter, and EDP identity control compatibility. |
| 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, code, EDP, diameter, L/D, shank, coating, point, margin form, coolant, and current cutting-data source. |
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 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 SUMOCHAM 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
- SUMOCHAM: Head diameter alone does not establish pocket, body, grade, geometry, or drilling-depth compatibility.
- 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.
