The DCS331M1 20V MAX* Jig Saw Kit has an all metal, lever-action keyless blade clamp designed for quick and easy blade changes and an all-metal keyless shoe bevel with four detents to make bevel adjustments easy. The variable speed trigger provides up to 3,000 strokes per minute to easily adjust speeds during cutting and 4-position orbital action for wood cutting. A removable shoe cover helps protect materials from scratches and the dust blower helps users see where they're cutting.
