Router bits and plywood thickness question
I am looking to purchase bits for my new router. Some of the straight bits like 1/2" and 3/4", I would like to use for creating dados for the garage shelves (I do not have a table saw). Unfortunately, I am noob at woodworking and I got really confused by the plywood thickness. The bits are 1/2" or 3/4" but the board thickness listed at Home Depot site is 15/32" or 23/32". I know that dado cut has to be exact to be strong. So could somebody tell me what actual bit thickness should I order? I was looking at MLCS bits but they don't even list 23/32" bits in their catalog.
