I have a 7.5 hp 36" Tannewitz vertical band saw that we don't use much

Could I put a VFD on it to cut metal?

You will need to add an extra cooling fan to cool the motor, if you
constantly run it at lower speed.

It would be better to reduce the power through a mechanical system
(belts, pulleys etc) than through VFD.
