The DEWALT DCS380B 20-Volt MAX Lithium-Ion Reciprocating Saw has a 4-position blade clamp that allows for flush cutting and increased positional versatility with tool-free blade changes. The 1-1/8 in. Stroke length allows the blade to cut more material in 1 pass than blades with shorter lengths, allowing you to work more efficiently. It has a variable-speed trigger with 0 SPM to 3000 SPM to provide increased blade control and faster cut speeds. The pivoting adjustable shoe extends blade life and allows for easier depth-of-cut control. It has a rubber over-molded comfort grip that delivers optimal balance and control even when used for long-periods. The double oil-sealed shaft resists contamination and increases durability.
