By constantly monitoring tool and battery operation, the intelligent switch module maximizes performance and prevents damage caused by overload or temperature build-up. This technology, combined with a tough outer casing and superb ergonomics means that XR Lithium-ion is truly "Tough on the outside and Intelligent on the inside". It is part of the intelligent XR Li-Ion Series, designed for efficiency and for making applications faster. The saw has a powerful and highly efficient PM58 DeWalt fan cooled motor with replaceable brushes, which delivers up to 3,700 rotations per minute for a fast-cutting action. It has an extremely durable tool design, including a cast magnesium base, which allows repetitive, accurate cuts.
