Dtg -

I have one that's probably pretty similar, except for being 110V. One thing I found was that there are numerous kinds of "bits" available, and it makes a lot of difference if you get the right one for the job you're doing. I've had no real difficulty cutting patterns out of 1" thick particle board (counter top stuff) with mine - after I finally figured out which cutter to put in it. It's slower, of course, than a "real" router, and a lot slower than a decent saw; but it's handier for small cuts or tight corners.

If you're talking about "normal" cabinet tops, you might want to take a look at what better bits are available before getting rid of the RotoZip. The tool usually comes with a few "general purpose" bits, but others shouldn't be hard to find.

If the heavy worktops you're talking about are over about an inch thick, then you do need a different tool. A "sabre-saw" would be good up to about 1.5 inch - maybe, but for really heavy stuff you want what's commonly called a "Sawzall" that has a heavy blade in-line with the motor axis. The heavier blade makes small radii difficult, but you use a "hole saw" in your drill to make the corners before you start sawing.
