Carbide Tipped saws vs HSS?

[limey1]

I previously posted this question in the wrong forum. I would like anybodys opinion on cutting stainless seamless tubing with either of these saws. They both seem capable, but with advancements in materials and cut profiles, its hard to tell which is better. I would definately be looking at low rpm, high torque, to reduce the amount of heat going into the material. Any thoughts/feedback would be appreciated.

I thought posting this in stainless engineering would prompt some feedback. If anyone thinks I posted this in the wrong forum, I apologize but it seems to be the relevant forum. Any feedback would be appreciated.
