The DeWalt impact rated holesaws have a double tooth design which strengthens each tooth for longer life and improved durability. The sharper tooth geometry cuts material faster for faster drilling with the thick, hardened backing plates preventing thread stripping.
The ejection spring allows for ease of use with no plug removal and the thin walled design is optimized for metal drill efficiency.
These holesaws are suitable for use on metal, aluminium, PVC and inox.
The DeWalt DEWDT8254QZ impact rated holesaw is 22mm
