    Slower speed on the burr and silicone spray on the burr helps quite a bit. A burr with wider openings between the “teeth” helps also.

    Sounds like a good idea to use cutoff wheels, I had thought about using a jig saw with a drilled hole at each end. But the cutoff wheels would be better.

    This. Probably more than 10 times as fast. Only downside is the cuttings. Those are nasty. A Dremel tool will be blowing smoke trying to do this with anything thicker than maybe 16 ga. I have had good success using the carbide burrs on aluminum also-just use a little WD40 to keep the burr clear. You can also use a version of Roy's method above-drilling a hole in both ends and cutting it out with a saber saw. That might be a little tricy with 1/4" holes. Of late, I buy the carbide burrs from Wholesale Tool. I had a couple MSC versions that the ball head separated from the shank.

    You can buy the individual Dremel burrs and all the rest of their cutting tools individually. Ace carries most of it. I still have the first Dremel tool I bought sometime in the early 60's along with 4 more recent versions. The best one is a 90's version with a keyless type chuck-still made in Racine.

    I own one carbide bit, cone shaped for my Harbor Freight air die grinder. Paid about $25 for it at a local tool supply store about 15 years ago. Still goes strong. Wear eye protection. This bit will make thousands of almost invisible slivers. They also stick to shoes and get into the house carpet. They hurt and are hard to find and see. I have ground out holes in 1/4" steel many times, including reaming a reciever hitch hole from 1/2 to 5/8. A bit of WD40 on the bit, or dry soap, or wax from a candle will help if doing a non ferrous metal like aluminum or brass. I use a dry bar of soap and just touch the bit to it while it turns slow to "load it" up with soap. My HF die grinder is dedicated to this one bit, the grinder was $9. I have other die grinders but don't like changing the bit.

    I use die grinders (pneumatic) every time I'm doing any work in the garage. lots of bits, wheels and such you can put on them. definitely good to have a few of them (at least 1 straight and 1 angled) if you plan on doing much metal work at all :) I use them alot more than I use an angle grinder.

    I have a Craftsman rotary tool very similar to a Dremel I also have two Dremels. I have used the things for all manner of work. I also have a die grinder which is good for heavy work but also a PITA as it is dependent on the compressor

    If you don’t have an air grinder a Foredom or Dumore is what they use in industry. Either one of these use 1/4” shank bits, make sure whatever, you get a double cut bit, so it won’t dig. A Dumore or Foredom will outlast 100 Dremels and are actually made for what you want. A good double cut carbide bit in a Dremel will remove quite a bit of material in short order, don’t push it let the tool do the work. I’ll be honest (no offense intended) most guys on here would not know a good bit from an ok bit if their life depended on it. I use these daily in my job, any bit you buy from anything except a specialized company making polishing tools are garbage, especially from a box store. Gesswein, DW sales, Congress tools, Falcon tool, these places sell good carbide bits for chewing up metal with rotary tools.
