Take these saws anywhere and use the included track to make perfectly straight, splinter-free cuts in wood. They are also called plunge saws because they can make plunge cuts. Control the speed of the blade with a dial; use slower speeds for hard wood and faster speeds for soft wood. A second dial lets you have precise control over the depth of the cut. These saws also have a riving knife that reduces kickback by keeping the cut material from pinching the blade. Connect a vacuum hose to the dust port to collect up to 90% of the sawdust created so you can keep your work area clean. Optional track clamps hold the track to your workpiece.
