Tackle the toughest cutting jobs with the DEWALT 20V MAX Brushless 3-in-1 Cut Off Tool Kit. This powerful tool features a high-performance brushless motor that delivers 550 MWO to power through stainless steel, rebar, pipes, channels, bolts, nails, steel, and even other dense materials with ease.

The included 3-in-1 design provides versatility for multiple applications. It comes equipped with a bonded abrasive wheel for general purpose cutting, a diamond multi-material wheel for masonry and hard materials, and a diamond tile wheel for ceramic tile. The quick-change design allows you to switch between wheels and accessories for the perfect set-up regardless of the material.

Bright LED Work Light

Illuminate your cut line even in poorly lit work spaces with the built-in LED work light. The long-lasting LED bulb casts 350 lumens in a wide beam pattern to brighten dark areas. No need to juggle a flashlight along with the cut off tool.

Depth Gauge for Precise Cuts

The adjustable depth gauge allows you to conveniently set the desired cutting depth prior to making a cut. The easy-to-read gauge features clear markings in both inches and millimeters, ensuring accurate depth control.

Dust Extractor Connectivity

The dust shroud includes a built-in AirLock connection point, allowing you to attach a DEWALT dust extractor (sold separately). Extracting debris and dust at the source keeps your workspace cleaner and your air clearer.

Ergonomic, Low-Vibration Design

An overmolded grip provides optimal comfort and control, even during extended use. The brushless motor also minimizes vibration for reduced hand-arm vibration. Weighing only 5.7 lbs, this compact tool is designed for easy maneuverability.
