A jigsaw is a power tool for cutting various materials which can also be used to make bevel cuts. It is equipped with a base plate. The saw blade which is positioned at a right angle to the motor shaft executes a straight or orbital stroke motion.
The hand-held bow saw is probably the best known type of saw which makes cuts by moving the saw blade back and forth. This principle was implemented in the electric sabre or reciprocating saw and the all-purpose saw. The circular saw with its rotary cutting motion is best suited for straight cuts. In order to make straight as well as curved cuts one needed the up-and-down stroke motion produced by a jigsaw. Jigsaws are available with knob or top handle, with universal motors, as cordless tools or with pneumatic motor. The high motor speed is reduced and transformed by an eccentric transmission into the typical up-and-down motion of the lifter rod. Mass balancing ensures low-vibration and quiet running. Orbital-action jigsaws permit the regulation of the orbital range in several stages. The "0" setting is recommended for metal, thin materials, and for fine and clean woodwork. Different orbital-action stages can be chosen during operation. The highest stage is recommended for quick cuts in wood or plastic. The stroke rate can be preselected by an adjusting wheel. Constant-Electronic maintains the stroke rate independent of load. The base plate can be tilted for bevel or mitre cuts. The saw dust blower can be switched off if an external dust extraction device is used. SDS-clic ensures quick saw blade changes without tools.
