Review on Starrett 248A Extended Overall Diameter by Will Murphy

I work for a manufacturing company and I had to remove the 3/16"2" long pin holding the gear to the shaft. Using a 3 pound steel hand sledge hammer, the rock drill was smashed. After a few curses, I was able to knock out the unruly pin. The puncher had light implements on it, but it did what it was supposed to do. Bought 2 but not sure if I need them. Great hit.
