Asked eBay to step in. Asking for full refund. Don't want a bar from them, even if it matched the photo. Don't trust this seller.
They think I want a discount, but what I want was what they listed, a functional solid carbide boring bar of the same construction as in the photo. It's clear that they don't have the bar that was photographed. Seems like Bait and Switch.
I'd keep the bar if it cost me under $2, but I sure wouldn't use it for anything that wasn't junk. Bar would probably fail on first cut.
Back to looking for a solid carbide bar. Most of the Circle Machine bars have dried up, or vastly increased in price. Could use a 1/4" and a 1/2" bar. Guess it's a waiting game to see when a decently priced one becomes available.
