band saw speed for metal?

for a reference, look up a video of a small portaband. they seem slow bit they work really well
I worked with one a while ago, cut a 5" pipe no prob but it took about 10 minutes. Ill get something going. This motor control is cool, if it bogs down it will ramp back up to speed under load. Wonder how it will function as the bandsaw starts to load up. I wonder why they don't make drill presses with this type of motor? Infinite speed control for 1/4 bits to hole saws.
