Air-powered routers spin cutting bits that remove material from wood workpieces to profile edges, create grooves and slots, cut joints, and trace shapes. Typical applications include forming decorative edges, mortising hinges and locksets, trimming laminate, and cutting openings for windows and doors. These pneumatic routers operate on compressed air and contain few moving parts, so they are lightweight to ease handling, run cool for a long lifespan, and require minimal maintenance.
