Kennametal KSEM vs Sandvik Coromant CoroDrill 860
Kennametal KSEM and Sandvik Coromant CoroDrill 860 are documented holemaking systems with different product architecture and application priorities. KSEM is Kennametal's modular drilling system built around reusable drill bodies and replaceable carbide center inserts. CoroDrill 860 is a Sandvik Coromant solid-carbide drill platform split into application-specific GM, PM, SM, and NM variants.
Side-by-side comparison
| Category | Kennametal KSEM | Sandvik Coromant CoroDrill 860 |
|---|---|---|
| System architecture | System architecture: machine-side drill body plus workpiece-side KSEM center insert, with compatibility controlled by diameter and insert seat size. | Official product records use complete ISO/ANSI ordering codes and separate Sandvik material IDs. |
| Documented application focus | Modular production drilling where a reusable body and replaceable carbide cutting point are preferred. | CoroDrill 860-GM for broad multi-material drilling where the exact GM item supports the work material. |
| Technical selection detail | Official records identify bodies by depth ratio and shank style, including WN, WD, SS, SSF, and structural-steel SFP variants across the available range. | Cited variants publish H8 or H9 achievable hole tolerance depending on the application-specific family and item. |
| Primary documented constraint | A body and insert with similar nominal diameters are not necessarily compatible; insert seat size and current compatibility data control the assembly. | The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended. |
| Manufacturer-guided selection | Capture both Kennametal material numbers and ISO/ANSI catalog IDs for the body and insert, plus depth ratio, shank, seat size, geometry, grade, and diameter. | Store the complete ordering code and material ID, including application suffix and grade, rather than shortening the record to CoroDrill 860. |
Best fit by application
Kennametal KSEM
- Modular production drilling where a reusable body and replaceable carbide cutting point are preferred.
- Capture both Kennametal material numbers and ISO/ANSI catalog IDs for the body and insert, plus depth ratio, shank, seat size, geometry, grade, and diameter.
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.
Selection notes
Use KSEM when its documented application focus and technical configuration match the operation more closely; use CoroDrill 860 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
- KSEM: A body and insert with similar nominal diameters are not necessarily compatible; insert seat size and current compatibility data control the assembly.
- CoroDrill 860: The 860 family suffix is an application distinction, not optional naming; GM, PM, SM, and NM data should not be blended.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
