ultimate flexibility

Though the 54V XR FLEXVOLT batteries offer all the power you need for a standard day’s worth of cutting, we understand that you might prefer the long term power of a cord for some jobs. With the AC adaptor, you can turn this 305mm 54V Mitre Saw into a corded one and saw non-stop.

Logo extreme runtime



Use the new XR FLEXVOLT mitre saw blades for the optimal cordless performance. The extra sharp, thinner carbide teeth pass through timber with less resistance and give longer useable life between re-sharpening. The optimised tooth form combining two alternate top bevel teeth followed by a raker tooth allows for the efficient cutting and cleaning of the kerf. This minimises the battery power required to make the cut line, resulting in more cuts per charge.


power of corded

Any 18V system has a limit to the amount of power it can deliver. DEWALT XR FLEXVOLT™ tools surpass the limits of an 18V system, delivering unprecedented levels of power. The 54V power opens up new applications on a cordless platform and also makes existing applications quicker. The faster application speed means that despite the higher voltage, less energy is used overall, which improves runtime on heavy duty tasks. And they are fully compatible with the entire 18V XR range, including chargers.
