For MDF and Plywood I recommend down cut bits. They press down as they cut, which will help prevent the splintered edges with plywood and chipping with MDF.  
Larger down cut bit should be available at your local hardware store with the rest of the router bits. Smaller ones need to be ordered on-line.
