The verdictOur take

The GST 12V-70 is Bosch's 12V barrel grip jigsaw, with an 18mm stroke and 70mm wood capacity, matching Milwaukee's M12 FJS on depth but with a shorter stroke than its 22mm. It weighs 1.5kg bare and Bosch rates it for 3mm in steel and aluminium, so it is aimed at light cutting and work from underneath. It has a worklight and a stroke rate thumbwheel, with two pendulum levels plus off.
