Perfect for Bauer from China via HF and will accept these or 1 1/8" Hex bits. In fact, I haven't tested it yet. I will be using it for replanting trees and digging in decomposed granite soil. I'm somewhat concerned (no pun intended) about the issues described in other metallurgy quality reviews .I believe this is a genuine Makita product based on the markings on the stock.If not that would be a misrepresentation and I don't think Revain would have done it.I will update this with another comment after I dug around a bit.
