The Bosch CRS180-B15 18V 1 1/8" reciprocating saw set comes with a powerful, compact saw with a D-handle, and a CORE18V battery. The saw is only 17.7" long and 6.35 lbs (tool only, without battery), and it delivers an efficient 1 1/8" stroke. The battery features next-generation Li-Ion technology that produces 80% more power than previous cells. Its CoolPack 2.0 technology provides up to 135% more cooling effect than the previous CoolPack system, and the battery is 100% compatible with all Bosch 18V Li-Ion tools and chargers. The tool can make 207 cuts in 2x4" on a single charge. The charger quickly charges a spent CORE18V battery to 80% in only 41 minutes and completely in 55 minutes. What/s more, the saw also features a Lockjaw system that allows for fast one-handed blade changes and has two speed ranges. This product is backed by a 1-year limited warranty.
