As I have been corrected, what I call a "Cold Saw" is really a Dry Cut Saw. Has a blade with teeth but uses no lubricant to cool the cut.
I have used the dry chop saw for awhile and would like to report what I've learned so far.
First, I love it and will never go back to an abrassive saw. It cuts Metal clean creating tight good looking joints. The metal is cold to the touch after the cut, thus the reason I call it a "Cold Saw". (Everybody I know calls it that too). Correctly used, the blades last for many cuts getting your money's worth.
The bad, but easily handled, is that it's really loud, but then again so is the abrasive saw. The blades are really expensive. Lastly and most importantly, if not used right, you can burn out a blade quickly and throw teeth thus getting real expensive. I've watched a few folks use the abrassive saw and the amount of heavy-handed crank put on some of those cuts would ruin a cold saw blade quickly.
I had thought this would be a good addition to the Metal Shop, but after using it awhile, I'm not sure it would work at DMS. It might get very expensive.
My solution, when I have a bunch of cuts I want to do at DMS, I'll bring my saw with me and/or use the machine shop Wet Saw.
