This is a 16.5 inch (42 cm) threaded mandrel. It is threaded on both ends. I am not sure who made the mandrel, but it does not have the standard threads and there is no dent ball included. It takes the dent balls with the finer threads than the Ferree’s dent balls. It is rusty and a little bent.

The shipping calculator sometimes charges too much. If it is over by more than a few dollars, I will give you a refund for shipping. Also, if you purchase more than one item, I will send them together to save you money.
