Sandvik Coromant CoroDrill 860 vs Seco Tools Perfomax
Sandvik Coromant CoroDrill 860 and Seco Tools Perfomax 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. Seco Perfomax is an indexable-insert drilling family for productive medium- and large-diameter holemaking.
Side-by-side comparison
| Category | Sandvik Coromant CoroDrill 860 | Seco Tools Perfomax |
|---|---|---|
| System architecture | Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs. | Seco identifies Perfomax as an indexable insert drill family with application-specific bodies and inserts. |
| Documented application focus | CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material. | Production drilling where indexable center and peripheral inserts support diameter range, chip control, and cost-per-edge decisions. |
| Technical selection detail | Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item. | Product records distinguish center and peripheral insert roles, geometry, grade, and item identifiers. |
| Primary documented constraint | The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended. | Center and peripheral inserts are not interchangeable roles. |
| Manufacturer-guided selection | Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860. | Build the assembly record with the drill body plus both insert positions, screws, torque, diameter, L/D, work material, coolant, and cutting data. |
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.
Seco Tools Perfomax
- Production drilling where indexable center and peripheral inserts support diameter range, chip control, and cost-per-edge decisions.
- Build the assembly record with the drill body plus both insert positions, screws, torque, diameter, L/D, work material, coolant, and cutting data.
Selection notes
Use CoroDrill 860 when its documented application focus and technical configuration match the operation more closely; use Perfomax 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.
- Perfomax: Center and peripheral inserts are not interchangeable roles.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
