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 .

Where it really _shines_ is _plaster_. It's good in drywall but I wouldn't
rush out to get one for that purpose unless I was installing the stuff for a
living. With plaster and a carbide bit though it's just plain wonderful.

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.

A Rotozip _is_ a router, but one with marginal depth adjustment and a rather
flimsy base that doesn't keep the bit square to the work--the problem with
the standard Rotozip bits in plywood and MDF is that they just plain don't
cut very fast and tend to burn. The Rotozip has 1/4" collets either in the
box or inexpensively available that allow it to be used with ordinary router
bits but it doesn't have any advantage I can identify over a router when
used with them.

The one time I tried to cut a plywood circle with a Rotozip I realized very
quickly that it is the wrong tool for the job.

If your objective is to have something small to cut plywood I'd recommend a
Bosch Colt or the like over a Rotozip.

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.

Or plaster.
