The Bosch GSA18V-125K14A 18V EC Brushless 1-1/4 In.-Stroke Multi-Grip Reciprocating Saw Kit with CORE18V Performance Battery features the first cordless recip saw with orbital and non-orbital sawing action for superior cutting in materials from wood to metal. The GSA18V-125 recip saw has an innovative and balanced angled-motor design and an efficient EC Brushless 18V motor. Its three orbital settings (0-1-2) allow optimized cutting in all types of materials. The saw delivers 0-2,500 strokes per minute at a labor-saving 1-1/4 In. per stroke. The Vibration Control counterbalance technology limits vibration, a long, easily reachable variable-speed trigger switch and a toolless blade-change system. The next-gen Lithium-ion CORE18V Performance Battery delivers 2X the power and runtime of standard two-layer 4.0 Ah 18V batteries with minimal increase in volume. The battery features high-power 21700 cells that deliver great power, combined with advanced battery design for greater efficiency. This CORE18V still features the Bosch-exclusive CoolPack 2.0 heat-management system, cutting-edge engineering and compatibility with all Bosch 18V Lithium-ion tools and chargers.
