How hot should a motor get on a bench grinder? Just recently got a Dewalt DW756 6" grinder and just after a few minutes of using it, it will get so hot I can't hold my hand on it for very long at all. Only been using it to sharpen drill bits, no hard pressure. Have an older duracraft bench grinder that also gets pretty warm but quite as bad as the dewalt. Is it normal for a bench grinder to get really hot?
