OK sports fans, here is another mystery I recently acquired. I have no idea what they are and neither did the seller at the junk store.
I purchased two out of the several they had. They were in various sizes, some as small as about 1/2 '' diameter. These are about 2 1/2 and 3" diameter.
They appear to fit into a chuck by the square on the shank.
