Abstract
Plug gauge for checking the diameter of a bore, including two movable arms with relevant feelers and a protective body defining two holes for the passage of the feelers. A sealing gasket seals the space between the holes of the protective body and the feelers, preventing the entry of foreign matter, such as chips and coolants, into the protective body.
