These CMT bit sets are perfect to use if you are making joints in plywood. Since plywood thickness tend to be actually in metric sizes and thinner than nominal dimensions, CMT offers you a way to work around the problem. These two Plywood Groove Sets include three specifically selected bits designed for making clean grooves and dadoes for accurate fitting joints. Use our 23/32 bit for 3/4 thick ply, 31/64 bit for 1/2 ply and our 15/64 for 1/4 ply. No gaps or sloppy joints, guaranteed. Available with 1/2 or 1/4 shanks.
