Bosch GSA18V-125N 18V Brushless 1-1/4" Stroke Multi-Grip Reciprocating Saw - Bare Tool

The Bosch GSA18V-125N 18V cordless 1-1/4-inch stroke multi-grip reciprocating saw executes aggressive structural wood demolition, nail-embedded stud cutting, cast iron pipe sectioning, and structural steel slicing. Driven by an EC brushless motor generating 0 to 2,500 SPM with Constant Response speed stabilization, this 7.7-lb demolition saw features selectable 3-position orbital cutting action to maximize aggressive wood stock removal or deliver smooth metal cuts. Built with an ergonomic angled-motor chassis, counterbalance Vibration Control mechanics, a toolless blade-change clamp, dual front-mounted LEDs, and Electronic Motor Protection, it equips commercial demolition crews, remodelers, and plumbers with balanced multi-position handling and continuous cutting velocity.

**Battery and charger sold separately.

Best Used For:

  • Nail-Embedded Framing and Structural Wood Demolition: Slicing rapidly through old-growth 2x4 framing studs, floor joists, and roof trusses using aggressive full orbital cutting mode.
  • Heavy Cast Iron and Steel Pipe Sectioning: Cutting straight, chatter-free channels through thick-wall metal conduit, black iron gas pipe, and cast iron soil lines in straight inline mode.
  • Tight Stud Bay Plunge and Overhead Reach Cuts: Navigating crowded utility channels, ceiling joist cavities, and HVAC soffits easily via the ergonomic angled-motor body.

Key Performance & Safety Features

  • Three-Setting Orbital Action (0-1-2): Dial selector allows instant adjustment between straight reciprocating stroke for metals and orbital action for fast wood clearing.
  • Long 1-1/4" Stroke Length: Extended stroke stroke trajectory removes more material per cycle to accelerate demolition pacing through thick lumber.
  • Counterbalance Vibration Control: Internal counterweight drive mechanism absorbs operational recoil to decrease hand-arm vibration during extended cutting shifts.
  • Angled-Motor Ergonomic Chassis: Innovative angled motor configuration optimizes balance and enables diverse hand grip placements for overhead and horizontal cuts.
  • Toolless Blade-Change Clamp: Robust spring-loaded blade holder facilitates quick, keyless blade swaps and prevents loose blade slippage under heavy load.
  • Constant Response Circuitry: Electronic governor maintains stroke speed under intense resistance while Electronic Motor and Cell Protection shield internal electronics.
