Reveal drop ceiling tiles hang down slightly past the “T’s” to offer a nice shadowed appearance for style. But cutting the edges is a pain and time consuming when done with a utility knife and straight edge as recommended. I have found a much faster and easier method.
I simply use a 3/8″ Rabbet bit with a router mounted on a table. You can set the depth of cut to match the factory edge and zip right along leaving a beautifully even and clean cut.
