steel circular saw

[Code54]

How about putting one of those blades in the chop saw? Would certainly have enough power and is probably built stouter than the average WW circular saw.

That is an interesting idea - not sure how fast the chop saw spins - maybe too fast????

Chop saws are way to fast. at least by a factor of 2

Also the published speeds for most of the worm drive saws seem to be in the 4400 rpm range, about 3 times faster than a cold saw.. Just like my vertical bandsaw, it is made for cutting wood and goes way to fast for metal even though metal blades are readily available for it.

Just for curiosity's sake, I looked up a few saws on Lowe's site.

Dewalt chop saw 4000rpm
Skil direct drive circular saw 5600rpm
Skil worm drive circular saw 4600rpm
Harbor Freight metal cutting 7 1/4" circular saw 3500rpm.

Looks like a chop saw is not that bad of choice. It's a lot closer to the rpm of the metal saw than the others.

I think the rage saws run 2500 rpm. 4000 is way high for that...

I have a Rage 7 1/4" skill saw, and love it. The blades hold up, if you use it for what it is designed for. They can be resharpened. I did buy a Lenox blade for it, but haven't used it yet.

Well I looked on rages web site and most of their 7 1/4 saws run at 2500 so I was wrong with the "factor of 2 statement" but still a chop saw at 4000 would be fast compared to 2500.. I was thinking they ran at 1500 like other cold saws but apparently not. I believe tho that as the blade gets larger you would need to run it at a slower rpm to maintain the samecut speed in surface feet per minute so a 14 inch cutoff saw blade if replaced with a 14 inch cold saw blade since it is larger would need to run that much slower. I do not think putting the cold saw blades in a machine not designed for them is a good idea.

I picked up a speed reducer for the chop saw that I have not used since I bought the HF cold saw. When I locate a cheaper priced metal cutting blade I am going to give it a try. The likely issues are that the saw will not enough torque with the speed reduced. Anybody have a line on a cheap 12" metal cutting blade?

I looked into buying one of the Evolation Rage saws, just about pulled the trigger, then I thought why? I think that saw is a high production saw, and I'm not in that big of a hurry. I think you'd get more bang for your buck with a port a band.
I've read where a carpenter's skil saw turns too many rpms for the steel blades. Maybe you should just use an abrasive skil saw blade in your saw.

I'm with you--portable band saw. I have an $80 cheapie from Harbor Freight and use Milwaukee 24 teeth per inch blades at slow speed (the saw has a variable speed trigger control with lock button). Cuts 1/4" 4x4" tubing like butter.

Here we go. The rage blades are rated for 4000rpm. If you have a 1" arbor, stick it in your chop saw and go. They don't have a 10" blade, an 8.25" will have to do.

My experience with these carbide tipped metal cutting blades is that speed kills (the blade). A 14" abrase chop saw turns much too fast for these blades. The 14" carbide blades are designed to run at 1000 - 1450 RPM.

Took this link from another thread.. This chop is 2800 rpm. Link

I am going to be "that guy" - I bought the harbor freight metal cutting circular saw for about $60 with the metal cutting blade and it has worked great!!! Even cut some 1/2 plate (more than I think you are supposed to cut). used it for several projects and to be honest if it blew up tomorrow I can say I got my moneys worth out of it and would get another one. It was cheap especially with a blade although it is a bit ugly.......

ME TOO! cannot beat it for the money. Made lots of angle cuts on 1/4" x 4" flat stock and could not believe it. Great for the money but best bet to buy with 20% off coupon. I got my money out of it already!

Even the blade that came with it has held up really well. I would have expected to had to replace it by now but it is still going strong!

Got a Milwaukee metal saw here a while back. It's rated for up to 3/4" plate and so far has done a great job for me. The thickest thing I have cut so far was 1/2" AR 400. It went thru it about as easy as cutting plywood with a skil saw. Very handy tool to have for just over $300.
