The 18V Cordless 4-Tool Kit is a convenient way to get into the Bosch's 18V platform. It does two jobs with one tool and goes from impact wrench to impact driver fast. The DDS181A Drill with Driver features a compact motor with the same power as conventional 18V motors at a lighter weight. It produces 600 In.-Lbs. max torque. The GSA18V-083 Reciprocating Saw is 15-3/4" long and only 4.4 lbs. (tool only), but it delivers 0-3,050 strokes per minute. The GLI18V-300 is a bright light with 300 minutes of runtime per amp hour. The kit comes with two 18V 2.0 Ah SlimPack batteries and a charger.
