Plunge vs Fixed Base Router

Plunge and fixed base routers both have a place in the workshop, and each one is best suited to specific routing tasks. Basically, use a plunge router when you want to rout in the middle of the workpiece or when making a stopped cut that doesn’t go all the way to the edge of the workpiece e.g. a mortise; use a fixed base router when you are not making a stopped cut and routing the edge of the workpiece.
