Bosch GSA18V-125K14A 18V Brushless 1-1/4" Multi-Grip Reciprocating Saw Kit

The Bosch GSA18V-125K14A 18V EC Brushless reciprocating saw kit delivers aggressive demolition and precision slicing across nail-embedded timber, structural lumber, cast iron pipe, and structural steel. Powered by an EC Brushless motor and a CORE18V 8.0Ah High Power battery, this 7.7-lb corded-equivalent reciprocating saw generates 0 to 2,500 SPM with an extended 1-1/4-inch stroke length for rapid stock removal. Featuring 3-stage orbital action selector settings (0-1-2), an internal counterbalance Vibration Control system, an angled-motor multi-grip handle design, and a toolless blade clamp, it ensures minimal user fatigue and versatile control during overhead framing cuts and tight-space plumbing rough-ins.

Best Used For:

  • Rough Framing and Demolition: Slicing rapidly through nail-embedded 2x4s, roof rafters, and wall studs utilizing aggressive 3-stage orbital action.
  • Mechanical and Plumbing Rough-In: Cutting heavy-gauge iron pipe, copper tubing, PVC drains, and strut channels smoothly in straight, non-orbital mode.
  • Overhead and Confined Space Remodeling: Working between narrow 16-inch stud bays and overhead ceiling joists using the balanced angled-motor multi-grip housing.

Key Performance & Safety Features

  • 3-Stage Orbital Action Selection: Allows users to toggle between straight stroke cutting for metal and aggressive orbital modes (0-1-2) for ultra-fast wood demolition.
  • EC Brushless Motor Drivetrain: Delivers maximum power efficiency, longer motor life, and sustained cutting velocity under heavy mechanical loads.
  • Internal Counterbalance Vibration Control: Minimizes reciprocating blade shake to reduce arm fatigue and joint strain during long demolition sessions.
  • High-Capacity CORE18V 8.0Ah Power: Equipped with advanced 21700 lithium-ion cells and CoolPack 2.0 heat management for 2X runtime and extended power output.
  • Glove-Friendly Toolless Blade Clamp: Quick-action locking collar enables rapid one-handed blade insertion and ejection even while wearing heavy work gloves.
  • Adjustable Pivoting Footplate: Extends blade cutting life by engaging fresh teeth along the blade length while maintaining stable workpiece contact.
