The Makita Reciprocating Saw combines a powerful 9 AMP motor with less weight (7.3 pounds) for all day use and improved performance. The JR3050T is powered by a 9 AMP motor with variable speed (0-2,800 SPM) and 1-1/8 inch blade stroke for efficient cutting. The JR3050T also features an internal dust blower system to clear debris from the line of cut for improved visibility, with a heavy-duty shoe and “tool-less” blade change for fast blade change and removal. The saw is engineered with all ball and needle bearings for longer tool life.
