I've never used one before but what's the word on the rotozip tool?


Pretty much a waste of money unless you use it for what it was originally
designed to do, cut dry wall .




I can see how it would be nice for drywall etc but I'm looking for a
better way to cut circles in 1/2" or 3/4" plywood or mdf board.
(rather than a router).

Goo luck, most bits are .125", 1/8", they bend, fle, chatter, and break.




Are these working looking at? -- is there a circle jig that works with
it?

Certainly you're moving less material with it than a router which may
be a good thing.

Nou unless cutting dry wall.
