Can someone who has experience with coldsaws please explain how these
differ in performance and blade lifespan (cost effectiveness) compared
to true coldsaws?

Thanks,

Dave

The only comment I can add is from a grunt's perspective.

I worked for a short time at a fabrication company that had a cold saw. It
was the most accurate, easiest saw that I have ever used.

Slide the material in there, adjust the angle, clamp it down, saw it, dry it
off, and weld it.

One could transpose angles right off drawings, and they would come out
exactly. No blade drift on miter cuts.

I even like my little HF band saw over a chop saw. BUT, if I ever get the
chance to get a cold saw for a decent price, I will go with one in a
heartbeat.

Whether it is for you or employees, it is a great way to accurately and
efficiently cut metal. Resulting in savings in time, waste, and accuracy.

They're the cat's meow.
