jig saw
Electric portable saw whose blade has an up-and-down motion; it is used for making straight or curved cuts.

The tool’s support plate, which rests on the surface of the piece to be cut. It can be inclined to make beveled cuts.
blade
It moves up and down but can also move from front to back, which increases the efficiency of the sawing.
power cord
Flexible electric wire housing the leads connecting the appliance to the electric circuit.
speed selector switch
Device for controlling the rhythm of the blade’s up-and-down motion.
chip cover
Protective cover preventing sawdust and fragments from flying toward the user or toward the cutting line.
handle
trigger switch

orbital-action selector
