Power tools use an electric, battery-powered, hydraulic, or pneumatic power source to perform a variety of tasks on the jobsite. Power saws cut through wood, masonry, and other materials. Cutting tools are used on jobsites and in production applications to cut workpieces to the required size. Routers are tabletop or handheld power tools used cut dados, rabbets, mortises, and chamfers in wood and laminates. Drills and drivers create holes and install and remove fasteners to join workpieces. Planers, jointers, and joiners surface and prepare wood for construction and joinery.
