The DEWALT 4-1/2 in. (114 mm) 18-Volt Cordless Cut-Off Tool has a 6500 RPM motor that provides high power for cutting and grinding metal, from rusted rebar to steel I-beams. And since there's no cord to hold you back, you can work anywhere, at any angle or height. This versatile tool will also accept a Zirconia-grit flap disk, stringer wire wheel or rubber-backed sanding disc so you can clean, smooth, shape and finish a wide variety of materials. It also features a convenient, large trigger switch with lock-off button and quick-change wheel release.
