The DeWalt DC385B is an 18-volt reciprocating saw. Because this saw is cordless, it may be used anywhere around the home or at job locations. Power for the unit is supplied by a rechargeable battery. The saw has a trigger that allows the user to adjust the blade speed as needed. An adjustable blade shoe lets you modify the depth of the cut and extends blade life. The saw produces a stroke length of 1-1/8 inch at up to 3,000 spm.
