Sandvik Coromant CoroDrill 880 vs Allied Machine 4TEX
Sandvik Coromant CoroDrill 880 and Allied Machine 4TEX are documented holemaking systems with different product architecture and application priorities. CoroDrill 880 is Sandvik Coromant's indexable drilling system using drill bodies and separate central and peripheral inserts. 4TEX is an Allied Machine indexable insert drill designed to increase penetration rates while using lower drilling forces.
Side-by-side comparison
| Category | Sandvik Coromant CoroDrill 880 | Allied Machine 4TEX |
|---|---|---|
| System architecture | Official body pages identify compatible central C and peripheral P insert interface codes separately. | Architecture: indexable drill body with replaceable multi-edge carbide inserts. |
| Documented application focus | Indexable production drilling using separate central and peripheral cutting positions. | Production drilling where indexable-edge economics and lower drilling force are priorities. |
| Technical selection detail | Bodies span different diameter, usable-length ratio, shank, and Coromant Capto configurations. | Allied positions the system around higher penetration with lower drilling forces. |
| Primary documented constraint | Central and peripheral inserts are position-specific and use different interface identifiers. | Center and peripheral insert positions may use different wear patterns and must be monitored separately. |
| Manufacturer-guided selection | Record the body ordering code plus every central and peripheral insert code, grade, position, torque, connection, and coolant condition. | Use 4TEX where indexable drilling economics, reduced cutting forces, and body reuse fit the machine and tolerance requirement. |
Best fit by application
Sandvik Coromant CoroDrill 880
- Indexable production drilling using separate central and peripheral cutting positions.
- Record the body ordering code plus every central and peripheral insert code, grade, position, torque, connection, and coolant condition.
Allied Machine 4TEX
- Production drilling where indexable-edge economics and lower drilling force are priorities.
- Use 4TEX where indexable drilling economics, reduced cutting forces, and body reuse fit the machine and tolerance requirement.
Selection notes
Use CoroDrill 880 when its documented application focus and technical configuration match the operation more closely; use 4TEX 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 880: Central and peripheral inserts are position-specific and use different interface identifiers.
- 4TEX: Center and peripheral insert positions may use different wear patterns and must be monitored separately.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
