I am finding an increasing need for a horizontal/vertical metal cutting band saw. I've been doing a lot of work with large diameter pipe (6"-8")and larger solids and have been cutting with cut off blades or plasma. Both have obvious limitations. I also have been cutting sheet that I would like a cleaner kerf than I get with plasma.
I have never used a H/V bandsaw before, and really know nothing about them. Can someone here who has had experience with these give me an idea what to look for regarding desirable options and etc?
Thanks!
