A little OT but can someone explain why small electric motors are rated only in amps while slightly larger ones are rated in HP? My Dad is looking at buying a new bench grinder and is having trouble figuring out how to compare various models from Delta, Ryobi etc. He isn't going to be happy with the performance of the smaller ones but won't be happy paying for the larger ones. He's looking for an 8" grinder. Any thoughts on brands/models?
