measuring tools

[topher5150]

I'm going to be getting some measuring tools for my job, and can't remember for the life of me what these things are called. They are for measuring ID you put the tool in the hole and twist the handle and two cylinders pop out then you twist the handle again to lock it pull the tool out and use calipers or a mic to measure it. Anyone remember what they are called
