The DC330B jig saw 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 at 0, 15, 30 and 45 deg to make bevel adjustments easy. The variable speed trigger provides up to 3000 spm 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. Battery and charger sold separately.
