For straighter, more accurate cutting in vertical and overhead applications, Makita has a solution with the 18V LXT Lithium-Ion cordless cut-out saw (model XDS01Z, tool only). it’s designed to cut openings in installed board, including drywall and plywood, and will cut up to 984 feet of ½” drywall on a single charge using a 4.0Ah battery (sold separately). to help prevent damage to objects behind the board being cut, it has a short ¼” stroke length with an adjustable blade depth up to 1-3/16″ (9/16″ in wood). for improved dust extraction, the XDS01Z has a dust port with a clear dust box for increased visibility. It is ideal for cut-outs and drywall repair applications.
