Cut-Off Wheel
Cut-off wheels are thin abrasive or diamond accessories for cutting, and must match the tool, speed, size, mounting system, material, and intended application.
Cut-off wheel types
Wheel construction and material rating determine what a cut-off wheel is intended to cut. A wheel should never be selected by appearance alone.
| Wheel type | Typical use | Key consideration |
|---|---|---|
| Metal abrasive wheel | Cutting compatible ferrous or non-ferrous metals when specifically rated | Check the exact material rating on the wheel |
| Masonry abrasive wheel | Cutting compatible masonry materials | Not interchangeable with a metal wheel unless the product is explicitly multi-material rated |
| Diamond wheel | Cutting compatible concrete, masonry, tile, or stone | Match the wheel design to the material and tool |
Cut-off wheel material compatibility
Cut-off wheel material compatibility depends on the wheel label and manufacturer rating, which should match the workpiece material, tool, speed, and cutting task.
| Material | Typical wheel category | Important check |
|---|---|---|
| Steel and ferrous metal | Metal-rated abrasive or other specifically approved cutting wheel | Confirm the wheel is rated for the metal and tool speed |
| Aluminum and non-ferrous metal | Wheel specifically rated for the alloy or non-ferrous use | Do not assume a general metal wheel is suitable |
| Concrete and masonry | Masonry abrasive or compatible diamond wheel | Match wheel, tool, and dust-control requirements to the job |
| Tile and stone | Compatible diamond or specialty wheel | Check the wheel’s material and application rating |
Cut-off wheel selection
Choosing a cut-off wheel requires matching its diameter, speed rating, arbor or mounting system, material rating, and cutting application to the tool and job.
- Match the wheel diameter to the tool and guard configuration.
- Confirm the wheel’s maximum speed rating is suitable for the tool.
- Match the arbor or mounting system to the tool.
- Use a wheel explicitly rated for the material and cutting application.
- Inspect the wheel and follow the tool and wheel manufacturer instructions before use.
