Hereof, can you use a Roundover bit on plywood?

If you used a 1/2″ radius piloted roundover bit, the pilot bearing will be able to ride along the bottom edge (the bottom 1/4″) of the 3/4″ plywood. IMO, that’s probably the bit you should use. A 1/2″ roundover is nice. When using a plunge router to do edge routing, you don’t use the “plunge feature” of the router.

Beside above, what is a beading bit? A beading bit is similar to a roundover bit (below) in that it applies a rounded shape to the edge of the stock. Beading bits often have a bearing tip for riding along the edge of the stock as it is cut.

Thereof, what is a round over?

Roundover bits create flush decorative edges perfect for table, drawer or cabinet edges and for small finish moldings. Roundovers are also called quarter rounds and they apply a convex radius edge. By substituting a smaller 3/8″ bearing (83019) an inset at the base of the cut produces a more decorative step.

What router bits do what?

Straight bits used to make cuts straight down into a material to form a groove or dado or to hollow out an area for a mortise or inlay.
