alternative add ons like a dremel

[azntiger0586]

im planning to modify my case, just some circles here and there.

i see alot of ppl reccomend the dremel tool, but i dont want to buy it just for this.

what can i use with a regular drill to cut steel? is it even possible?

How big are these holes?

Here is a topic at another site that might have some ideas. I have not read all of the thread though.

The dremel bits will do no good in regular drills because of the rpms. The dremel tools run 30,000-35,000 rpms where your typical drill averages 700-1000 rpms. If the holes will be perfectly round then a hole saw like previously linked does a great job if not you can get the standard dremel usually for around $30 or I got the Menards el cheapo knockoff for $15 on sale normally $21 with various cutting wheels and attatchments.
