It clears out clogged fittings. You attach the tool to the fitting and hit the top and it clears out caked up grease that would otherwise prevent you from adding grease to a spindle etc.
On the right is a picture of a pin vice.
You got it! I've had that grease fitting tool for several years now, and never once used it! It has the extra hose and a fitted plastic case.
