Stud Puller 4pcs Socket Set 1/2 Drive Roller Type

These stud removers are a good value. That being said, they could be improved. They probably won't work very well for getting broken studs/bolts out if they are not extending out more than 1/2". They do a pretty good job of removing and installing studs while leaving three small indentations on the threads of studs that are more difficult to turn. In my opinion, it would be better if the sockets for the smaller diameter studs were not ½” drive.
