Details

The MSM-16-1/2E can calibrate micrometers from 1/2" to 6.0" diameters in 1/2 inch increments. The MSM-16-1/2M can calibrate micrometers from 12.5mm - 150mm diameters in 12.5mm increments. Case hardened, stablilized, ground and lapped to +/- .0001" or +/-.0025mm. Both Micrometer Set Masters are Chrome plated to reduce wear and prevent rust. Micrometer Set Masters are used to calibrate and set micrometers. The master is superior to gage block calibration because they do not require block stacks so it is much faster to inspect the linear range of the tool. Micrometer set masters indicate the wear on the micrometer anvil better because they replicate how the micrometer is used.
