M1 Star mechanical bore gages (MBG) are manual instruments for checking I.D., ovality, or taper of through bores, and blind and super-blind bores. They sport mechanical measurement-transmission systems that last for more than 10 million measuring cycles. The systems interface with any dial indicator, digital indicator, or pencil probe. Application range is 0.12 to 11.81 in.
