Yep, agree with Keith, can’t beat step drills for thin stuff. Metal or plastic.

He said cut sheet metal not drill. Maybe he is looking for one of these.

That question sound like another recent one that I just quit reading the thread on. because it's not even moderately defined. :-(

The nibblers work okay, though I wouldnt waste my time on a cheap import copy. If you are paying under $150 for it then you will have a lot of frustration. The key to the nibblers is never let it touch any metal unless your drill is at full operating speed. Any slower and the die snaps off and you get to spend half again as much for a new die. The cheap imports really are maxed at 18 gauge and better at 20 gauge.

If you are doing straight cuts or a bit broader curves there are a lot better tools to be had. I use a Milwaukee nibbler for 16 gauge, the knd that cuts out a 1/4” wide coupon out of the middle. Works well for 16 gauge, but really shines at 18. I also use an opposed blade shear that works great in 16 gauge, but distorts one side and doesnt like sharp curves.

yes, I'm referring to cutting. I'm making a cell phone stand for a co-worker and I'm trying to cut an oval hole in the center of 16 gauge sheet metal. I was able to cut an opening out with my dremel tool. and between that, a grinding stone attachment and a couple of files was able to get a passable hole. I thought that there might have been an easier way of doing it. sometimes I'm just impatient, and just want to get things done in a hurry. Thanks for the responses.

lol
I immediately thought of a cheap little tool I used to occasionally buy from a local re-seller, probably 20 years ago.

The Malco Sheet Metal Cutter, "attaches to any electric drill". Just a handle with an adjustable index point. They came with a very brittle carbide cutter, just a side-cutting 1/4" drill that would drill the starting hole and cut on the side if you were very careful. You had to have the material secured well, any instability would trash the cutter and render your tool useless. This was especially critical at the end of the cut since your index point was in the piece you were cutting out.

I cut a few circles successfully and I broke several cutters.
I also sold several of these on ebay for ten bucks or so. I found one without the cutter in a closet just now and I think I might have one or two out in the shop, somewhere. I paid $1.96 for this one.

Look at the asking prices on ebay now.

I'm not sure your gonna cut 16ga. with either, drill type rotary bit or nibbler bits I have some high-end nibblers and you're wanting to cut 16ga. I think even with new cutters will give the cutters and the tool it's self, hell. and end up making very few cuts per bit/cutter without breaking or dulling.
