Plunge router bits are generally used with a plunge router for making deep surface cuts, such as for lettering and inlay work, as well as for general routing, including straight grooves, mortises, rabbets, dadoes and trimming. Plunge-style panel router bits can also be used to cut openings for sinks, windows and doors.
