Kennametal KSEM vs Allied Machine Revolution Drill
Kennametal KSEM and Allied Machine Revolution Drill 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. Revolution Drill is Allied Machine's adjustable large-diameter indexable drilling system for drilling from solid or opening an existing hole.
Side-by-side comparison
| Category | Kennametal KSEM | Allied Machine Revolution Drill |
|---|---|---|
| System architecture | System architecture: machine-side drill body plus workpiece-side KSEM center insert, with compatibility controlled by diameter and insert seat size. | Can drill from solid without a pilot or open an existing hole. |
| Documented application focus | Modular production drilling where a reusable body and replaceable carbide cutting point are preferred. | Large-diameter holes on machines with limited available horsepower. |
| 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. | Allied states that the system can ignore core shifts up to 3.175 mm (0.125 in) in applicable opening operations. |
| 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. | Cartridge setup and diameter adjustment require controlled assembly and measurement procedures. |
| 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. | Use Revolution Drill when large-hole flexibility and low-horsepower capability justify an adjustable multi-insert system. |
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.
Allied Machine Revolution Drill
- Large-diameter holes on machines with limited available horsepower.
- Use Revolution Drill when large-hole flexibility and low-horsepower capability justify an adjustable multi-insert system.
Selection notes
Use KSEM when its documented application focus and technical configuration match the operation more closely; use Revolution Drill 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.
- Revolution Drill: Cartridge setup and diameter adjustment require controlled assembly and measurement procedures.
- Normalize diameter or cutter size, reach, interface, work material, machine conditions, coolant, and acceptance criteria before comparing performance or cost.
