Undersize Plywood Bits

We all know that plywood is not actually 3/4”, 1/2” or 1/4”, and this can make it hard to create tight joints in plywood projects. “Undersized” plywood bits like this set from Freud make it easier to create dados that fit the actual plywood thickness.

In the video, Ralph shows you how these bits work and provides a clever bit holder design that let’s you check the fit before you cut. There is also a pro tip on designing boxes that build square and stay square.
