The four major players on this ingenious little time-saver include a jab saw with a special sheetrock reciprocal blade, a keyhole saw, a power driver, and a speed driver for both screws and nuts. A keyless quick change locking chuck accepts both quick change bits and industry standard reciprocating saw blades, while a swivel locking chuck holds all the blades and speed shank power bits so that, well, you don't have to. Finally, the comfortable handle easily locks in either the straight or pistol grip position, depending on your mood. Kit includes: 3 saw blades (drywall, metal/PVC and wood), 7 insert bits, 1 hex to square adaptor, 1 quick change handle, 1 holster with belt clip, and 1 bit extender. Imported.
