The verdictOur take

The GST 18V-LI B is Bosch's earlier 18V bow handle jigsaw, with a 23mm stroke, 2,700 strokes a minute and 120mm wood capacity, against 26mm, 3,500 and 125mm on the brushless GST 18V-125 B. It weighs 1.8kg bare and declares 6 m/s² cutting boards. Bosch UK still lists it through Bosch Partner dealers in an L-BOXX with three blades.

Tool weight worked out by adding each pack's weight to the bare tool, using the makers' figures. The maker's own with-battery figure can differ slightly. We may earn a commission on retailer links.
