Ive used all the big name saws when doing metal stud framing, and they all work just fine!! They have these new saws out that look like a regular skill saw, but they are for metal. I have not tried one, but the guy at the tool and fastener store was really impressed with it, sayes it cut through 2" solid steel like wood. The down side is its close to 300 bucks.
you can get 7 1/4" metal cutting discs which will fit regular circular saws. no need for a $300 saw... or if your cutting sheet metal and don't mind making a racket.. turn a cheap wood blade around backwards on a circular saw, and it will cut metal.
Matt, i just saw the blades at HD yesterday, im still a little uneasy about that though! Skill saws like to bind up to much, i can do things with a skill saw that scare most men, but cutting metel with one scares me!
Your right about turning the blade around, it works real well on aluminum soffit and siding material, but be carefull!
Thanks for the information, I did not know a chop saw could handle metal. I almost bought one for cutting wooden rafter beams on our recent 20'x30' "Sun Room" addition but after we cut out one pattern beam with the appropriate notches for the edge of the roof I was able to make 34 copies with just a hand circular saw. For steel rectangular tubing on my Brookville frame I made an additional crossmember out of 1 1/2" x 3" rectangular tubing by taking a stock piece to a guy who has a pro fabrication shop who took his Chemistry from me and he cut both ends on an angle for me free on a very neat metal miter hacksaw setup but that looks like it is really expensive since he can saw 4" square (hollow) beams on it! Anyway with the miter angle on the hacksaw I got a really good fit to the bevel on the Model A frame and welded my safety U bracket for the drive shaft to the bottom of the new crossmember.

Don, just make sure you're looking at a chop saw for metal and not a miter saw for wood....... Don't think I'd use a chop saw on wood rafters......Quote:

Dave, My son-in-law used a neat chop saw for all the crazy angles in the interior wood trim, but I see what you mean on notching the rafters. Anyway, I have not seen a chop saw used on metal. Several special pieces I have farmed out locally always used a cut-off hack saw or the fancy miter hack saw.

I do use my no name miter saw with a cut off blade for steel occasionally and so far have ruined a bed insert and embedded slivers in the aluminum housing - but no big deal:CRY: as it still works just fine. I don't do enough fab work to justify a specialty saw.
I also have a HF chop saw and it has performed well, but I am just a hobby guy, pretty light use. What I do have that I highly recomend is a metal blade from www.bulletindustries.com.

Sooo much better than an abrasive blade. Joe
