Have the 4 1/2-5 and this 4 1/2-6". Both stand up to heavy grinding. I never touch a corded grinder unless I run out of battery. I would have burned out a corded grinder a long time ago with abuse these take. They are not the same as the old cordless grinders. They need the big batteries to perform though. I only use the 6 and 8 amp batteries.
