Kennametal KSEM vs OSG A Brand ADOX
Kennametal KSEM and OSG A Brand ADOX 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. OSG A Brand ADOX is a coolant-through solid-carbide drill family for ferrous and non-ferrous materials.
Side-by-side comparison
| Category | Kennametal KSEM | OSG A Brand ADOX |
|---|---|---|
| System architecture | System architecture: machine-side drill body plus workpiece-side KSEM center insert, with compatibility controlled by diameter and insert seat size. | OSG describes redesigned coolant holes for greater flow at the cutting edge. |
| Documented application focus | Modular production drilling where a reusable body and replaceable carbide cutting point are preferred. | Coolant-through production drilling in ferrous and non-ferrous work materials. |
| 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. | EgiAs nano coating and a wavy cutting-edge design are listed family features. |
| 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. | ADOX, ADO, ADO-SUS, and length variants are distinct families/configurations. |
| 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. | Record OSG list number, item number, diameter, flute length, overall length, L/D, shank, coating, and coolant requirements. |
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.
OSG A Brand ADOX
- Coolant-through production drilling in ferrous and non-ferrous work materials.
- Record OSG list number, item number, diameter, flute length, overall length, L/D, shank, coating, and coolant requirements.
Selection notes
Use KSEM when its documented application focus and technical configuration match the operation more closely; use A Brand ADOX 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.
- A Brand ADOX: ADOX, ADO, ADO-SUS, and length variants are distinct families/configurations.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
