Rail and stile door construction has been around for centuries and is the most common way to build doors for cabinets and furniture. Our rail and stile router bits will enable you to create your own frame-and-panel doors. Cope the ends of your rails with 1 bit, and then switch to the second bit to route the inside edge profile in all your door parts. The included panel raiser cuts the artistic profile on the center panel which reduces the panel's thickness to properly fit in the door frame's groove.
