Hello All & Happy Thanksgiving,
Quick question for the brain trust, all things being equal, (wheel size, rpms, atmospheric pressure, COO, etc) which is more important or would be the more desirable rating for a bench grinder motor? Something rated at 1/2 hp & 3.5 amps or 1/3 hp & 4.7 amps. Are they roughly the same, is one motor "working harder", or am I comparing apples to oranges? Thanks for your input.
Found this thread which mostly answered it but sill interested in any further thoughts....

Does amperage draw matter on bench grinders?
In looking at some older Craftsman bench grinders, I've seen some odd numbers. My 1/4 HP block grinder has an amp rating of 3.8, while my older-stype 1/3 HP block grinder has one of 3.6. And I've seen 1/2 HP block grinders rated at 5.8 amps, a fairly large step up. How much does amperage...
