A jigsaw make the cuts in an up-and-down motion, rapidly. There is a key factor for having excellent results with a jigsaw, which is matching a specific blade to the type of material you'll cut. You can check out the blade package to find out what material the blade cuts best. These materials could be plastics, tile, wood, metal, etc. so remember that using the right blade is the key to cutting various materials. Modern jigsaws are equipped with a technology that gives the blade the ability to move in pendulum action that is moving backwards and forwards. This kind of movement of the blade, makes the cutting process considerably faster. Jigsaws are suitable for making short crosscuts on a board. They also work well for cutting complex shapes and curves in wood and also lots and lots of other things could be done with a jigsaw from doing a hobby projects to installing a kitchen sink. Jigsaws are not suitable for cutting curves in very thick boards and their blades tend to bend if you do so.
