Sandvik Coromant CoroDrill 860 vs Guhring RT 100 FB
Sandvik Coromant CoroDrill 860 and Guhring RT 100 FB 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 FB Series 6596 is a two-flute, coolant-through flat-bottom carbide drill.
Side-by-side comparison
| Category | Sandvik Coromant CoroDrill 860 | Guhring RT 100 FB |
|---|---|---|
| System architecture | Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs. | Series 6596 is approximately 3xD with a 180-degree point. |
| Documented application focus | CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material. | Flat-bottom holes and low-burr exits. |
| Technical selection detail | Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item. | It uses carbide, nano-FIREX coating, internal coolant, and an HA shank. |
| Primary documented constraint | The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended. | Series 6596 and micro Series 6496 are not interchangeable. |
| 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, EDP, code, diameter, L/D, point, shank, coating, coolant, and catalog revision. |
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.

- Flat-bottom holes and low-burr exits.
- Store series, EDP, code, diameter, L/D, point, shank, coating, coolant, and catalog revision.
Selection notes
Use CoroDrill 860 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
- 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 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.
