The Bosch CRS180B 18V Reciprocating Saw is built to easily move through hard tasks in places other reciprocating saws can't fit. It has the best power to weight ratio in its class. And at only 17.4" long and 7.6 lbs, this formidable but compact cordless reciprocating saw allows electricians or plumbers with a tool that delivers an efficient 1-1/8" stroke, to remove more material per stroke. The tool's light weight is ideal for continuous cutting over the head. The easy to operate Lock-Jaw™ blade change system allows for fast one handed blade changes. It has two speed ranges, 0-2,400 SPM and 0-2,700 SPM, to match the speed of the cut to the material, and it easily handles multiple materials. The CRS180B is a bare tool, the battery and charger are sold separately.
