Not sure what to call it or what I originally made it for, but it's gotten a lot of use and a little bit shorter over the years. A long 3/8 pipe ripple and 3/8 brass cap. I use mainly for driving out races and bushings. I used the other day on some wheel bearing races.
Once the end gets buggered up I just trimm it off and carry on.
I used it a while back on some diffential bearing races, it's getting a little short and hard to grip so I'm going to make a new one for the next project
