Bosch GST 18V-125 S jigsaw — specs & overview

The Bosch GST 18V-125 S is a cordless jigsaw powered by an 18V battery system. It features a brushless motor that helps maintain efficiency during heavy use. This tool uses T-Shank blade fittings for quick changes. The device weighs 1.9 kg.

You can adjust the stroke rate between 500 and 3500 strokes per minute. This range allows you to switch from slow, controlled cuts in metal to rapid movements in timber. A 26 mm stroke length provides the necessary momentum for deeper work. The saw handles wood up to 125 mm thick and steel up to 10 mm.

The pendulum action feature helps clear sawdust from the cut path. This setting is useful when you need to increase cutting speed in soft materials. You can also tilt the base to a 45 degree bevel for angled cuts.
