If I read the RPM value correctly, at 3450 RPM, it would be suitable for an arbor type grinder or a T&C type grinder.
If you can't find a use for it, send it over the Mtn to me!

Edit: Do not use this motor to directly replace a 1725 RPM motor! Serious injury could result. If replacing a 1725 RPM motor you will need a speed reducing jack shaft!
