Instead of revolving blades, jigsaws cut with a back and forth or up and down motion.
Jigsaws are completely different than circular saws. Instead of revolving blades, jigsaws cut with a back and forth or up and down motion. Blades vary in tooth numbers and composition. They’re used to cut metal and plastic as well as wood. Fine-tooth blades are used for sawing veneers, while coarse tooth-blades are for rough and fast work.
