Sandvik Coromant CoroDrill 860 vs Guhring RT 100 U
Sandvik Coromant CoroDrill 860 and Guhring RT 100 U are documented holemaking systems with different product architecture and application priorities. CoroDrill 860 is a Sandvik Coromant solid-carbide drill platform split into application-specific GM, PM, SM, and NM variants. Guhring RT 100 U is a coolant-through carbide drill platform with distinct depth and shank series.
Side-by-side comparison
| Category | Sandvik Coromant CoroDrill 860 | Guhring RT 100 U |
|---|---|---|
| System architecture | Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs. | Series 5610 is a 3xD nano-FIREX, 140-degree RT 100 U with coolant and HE shank. |
| Documented application focus | CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material. | Production drilling in the material groups available for the exact RT 100 U item. |
| Technical selection detail | Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item. | Series 5511 is the 5xD nano-FIREX, 140-degree HA-shank branch. |
| Primary documented constraint | The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended. | Depth, shank, coating, margin design, diameter, and EDP identity control compatibility. |
| Manufacturer-guided selection | Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860. | Store series, code, EDP, diameter, L/D, shank, coating, point, margin form, coolant, and current cutting-data source. |
Best fit by application
Sandvik Coromant CoroDrill 860
- CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material.
- Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860.
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 CoroDrill 860 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
- CoroDrill 860: The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended.
- 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.
