The 18V LXT Lithium-Ion Cordless Cut-Out Saw (XDS01Z) is designed to cut openings in installed board, including drywall and plywood, and will cut up to 984' of 1/2" drywall on a single charge using a 4.0 Ah battery. To help prevent damage to objects behind the board being cut, it has a short 1/4" 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.
