I need a blade that will cut holes in PC cases, but my case is rather
think steel i belive, even with a holesaw and my drill it takes a fair
while to cut a hole in it.

Just wondering what kind of blade and type i would need to cut a 120mm
sized whole in my case ?

The blade that came with the Dremel did not last very long cutting the
hole i wanted it did make some progress but was ground down to nothing
rather quicky :(

Just need some info on the blades that will cut like a hot knife
though butter :), this is just for me, if i wanted to do this alot i
would get somthing more heavy duty.

Thanks.

a hole saw should easily cut through any computer case...
just make sure you get one specifically designed for cutting metal...
i use such saws for my job and can go through 1/8th " steel with no problems
(use a little oil with it)
sounds like you might have been using one designed for wood

Like philo said, make sure it's a metal cutting holesaw and that the
section of the case you're using it on is anchored. A little cutting oil
on the blade wouldn't hurt, either. For metal cutting with the dremel I
use the reinforced cutting wheels. There's a lot of information and
advice on line about the different techniques to use when cutting
computer cases with these.

A little more expensive, a diamond edged cutting wheel also works well.

how good are they for cutting tight curves?

About the same as the regular cutting wheels. I think you're better off
clamping piece you want to cut to some wood, and using the hole saw. You'll
get a much neater circle that way, and you can clean it up with a grinding
stone. A little tip with the hole saw, run it in reverse while cutting. It
won't rip your arm off if it gets snagged, and it cuts a little easier.

The reason I asked is that the regular cutting wheels have some flex to
them (and they can also gind a curve a bit).
 
Can you get a Dremel 120mm holesaw dimond tiped one ?

Would not have to be heavy ?

Thanks for all the info i think ill have to stick with the hole saw
for my holes :), and get a better one to make the cutting easier.

Thanks again.
