This 18V cordless jig saw is optimized for curve cuts, even through thicker material. The Bosch GST18V-60BC 18V Barrel-Grip Jig Saw features a brushless motor that delivers corded performance, with 0 to 3,800 strokes per minute speed. This barrel-grip jig saw provides an easy-to-reach pulse-activated double-sided switch to accommodate working with either the left or right hand. It features an adjustable blade guide/channel, which minimizes blade deflection while performing straight or curve cuts. The jig saw has four pendulum stages, to shift from fast cutting to cleaner cuts. Connecting to the jig saw allows user to pre-select speeds, turn the light on and off, and provide information on drop control events via Bosch Toolbox App. This jig saw features an adaptive speed-control setting, which will dial down the strokes per minute to control the entry point of the blade and the workpiece. Once the saw blade touches the workpiece, the jig saw will resume the selected speed, to provide the best control and precision. This jig saw also features a blower that can be switched on and off. The jig saw is compatible with guide rail and circle adapter. The jig saw has extended upfront soft-grip areas and a small barrel-grip circumference for greater tool control. The cut lines stay visible due to the dust blower and LED light. The jig saw features a tool-free T-shank blade-change system. The large die-cast aluminum footplate with no-mar plastic overshoe to help prevent damage to the workpiece.
