I tried to rotozip my way thru a double baffled .75" mdf wall once. ONCE! Its great for drywall....mdf...not so much.

Use a jigsaw...or a router.

jigsaw.

i tried the same thing, after about 30min to get half a hole done i went to my uncle and borrowed his jigsaw. now i own a jigsaw and a router(havent used it yet, also wish i would have known to get the spiral upcut bit)

also get the circle cutting jigs from parts express for the router. they'll make your life so much easier
