The DeWalt Cordless Reciprocating Saws have the power you need without the bothersome cord. An integral part of these Reciprocating Saws is the four position quick-release blade clamp. This allows the user to switch the orientation of the blade into four positions (up, down, left, right) which is handy when working in tight spaces. This component coupled with the ability to change blades easily with the lever-action keyless blade clamp makes the DeWalt Cordless Reciprocating Saws easy and efficient to use. All of these features make the DeWalt Cordless Reciprocating Saws even more versatile tools when combined with the variable speed system ranging from 0-3,000 SPM.
