Bosch GSA18V-126N 18V Professional Brushless 1-1/4″ Reciprocating Saw – Tool Only

Built for fast, controlled demolition and metal cutting, the Bosch GSA18V-126N combines a long 1-1/4 in. stroke with up to 3,000 SPM to move material quickly on the job. As part of the PROFACTOR™ lineup, its BITURBO Brushless™ motor is engineered to take full advantage of CORE18V® High Power batteries, delivering corded-like performance in an 18V form factor. An inline body helps with close-to-wall cuts, while the orbital/straight switch lets users choose rapid wood removal or a straighter stroke for pipe and metal. A clear LED worklight, tool-free blade lever, and an adjustable footplate round out a setup intended for daily professional use.

Control and safety are core to the design. The saw’s user interface provides access to KickBack Control, adaptive speed control, and end-of-cut detection, which can stop the tool when the blade exits the work to help prevent accidental damage. With six speed settings, dual vibration dampening, and a convenient saw hook, this 18V reciprocating saw is ready for framing tear-outs, window cut-downs, pipe cuts, and general demo on wood, nail-embedded material, and common metals.

Bosch 18V Professional Brushless 1-1/4″ Reciprocating Saw At a Glance

• 1-1/4″ Stroke, 0–3,000 SPM: Moves more material per stroke for faster cuts.
• PROFACTOR + BITURBO Brushless: High-output 18V performance optimized for CORE18V batteries.
• KickBack Control: Helps limit sudden reaction torque during a bind.
• End-of-Cut Detection: Can stop the tool as the blade exits to reduce unintended cuts.
• Adaptive Speed Control: Smooth, controlled starts that ramp to the selected speed.
• Orbital/Straight Modes: Choose aggressive wood cutting or straighter strokes for metal.
• Dual Vibration Dampening: Helps improve comfort and accuracy on long passes.
• Toolless Blade Changes & Adjustable Footplate: Faster swaps and longer blade life.

Markets

• Framing and Remodeling: Rapid demolition and rough openings in lumber and sheathing.
• Plumbing and HVAC: Cutting pipe, duct, and hangers with controlled starts in tight areas.
• Electrical and Low-Voltage: Conduit and hardware removal with close-to-wall access.

Professionals in framing and mechanical trades benefit from the saw’s balance of speed and control. Orbital mode clears wood quickly during tear-outs, while inline (straight) mode keeps the blade tracking on steel, copper, and cast components. The six-position speed selection and adaptive start help prevent jumpy entries and wandering cuts, and KickBack Control provides an added layer of confidence when a blade pinches. Crews also gain productivity from toolless blade changes and an adjustable footplate that lets them use fresh tooth zones for even wear. Paired with CORE18V packs, the GSA18V-126N delivers consistent cutting performance across demo, retrofit, and service tasks.
