This 18V jig saw delivers powerful and manageable cordless cutting, with its ergonomic, well-balanced barrel-grip design. The GST18V-47 18V Barrel-Grip Jig Saw has extended upfront soft-grip areas and a small barrel-grip circumference for greater tool control. It provides a variable-speed dial - from 550 up to 2,700 no-load strokes per minute - to match the speed to material. The jig saw has a stroke length of about 1 In., delivering a cutting capability up to 4.7 In. in wood and up to 0.8 In. in aluminum. It has four orbital-action settings for cut control. The saw also has a large die-cast aluminum footplate with no-mar plastic overshoe to help prevent damage to the workpiece. The cut lines stay visible due to the dust blower and LED light. It features a tool-free T-shank blade-change system
