Query: This is heavy duty?

The digger's length is a big help for tired backs and even without flat edges it held pretty tight in my drill - 1/2 inch Milwaukee. The problem is how easily it bends. I know the length is a factor, but my soil is probably as soft as it gets outside of a pot or flower box. First time it hits anything, root, rock or whatever, it'll bend. After that it's pretty much useless. Instead of a 2 inch hole you get anything but and the loose dirt is always knocked back into the hole. In sum, you get what you pay for and this is OK as a disposable.
