    Actually, they look more like cold milling teeth they grind asphalt with. Did you find them near road that was recently repaved?

    actually, everyone is right, they are used for excavating. i still have a few types laying around myself. if i remeber right, it was vermeer, that came up w/ that thrust washer design first. it helps on the wear of the face of the pocket holder, and helps keep sand/debri out of the bore/pocket cleaner, so tooth can rotate/spin during use. when/if tooth cant spin freely from debri, it wears super quick, along w/ outside of pocket sometimes.. the pocket/bit holders are much more expensive compared to the tooth. vermeer had some really good simple ideas (leave it to the dutch engineers) . i used to rockwell test there stuff compare to ditch witch/ballantine/case/ etc in the 90's. even made my own bit holders for same design teeth on smaller scale. i still have a hundred of them i never used, still black from the heat treat. you can sell them on ebay, just measure the shank/band w/ a calipers and post it. the ones i used/made were .735 - .765
