Ian,
Your correct. I wouldn't use a Dremel tool on anything above 0.060" thick which
is regular PC board like most everything uses. Then you need the router
attachment and a two flute straight cutter with a 1/8" diameter. They make
both, and I bought mine at Lowes who are a home building supply here in the
states. By the way, the newer Dremel tools have a little more torque than the
old ones did. These are the ones that you can use a flex shaft hand tool with.
If I were to cut anything over 0.060" material, I'd try one of those new zip
routers with a 1/4 inch bit. They are designed to cut blue board which is the
hard stuff you place behind tile in a shower. That stuff is 1/2" thich so a
0.25" thick piece of PC board shouldn't be a problem. If you have a regular
small router, it would work as well, probably better.
Best,
Will
