Details

The MSM-01-1E micrometer master can calibrate micrometers up to 1.0" with steps from .10" - 1.0" diameter. The MSM-01-1M micrometer master can calibrate micrometers up to 25.0mm with steps from 2.50mm to 25.0mm. Both are supplied in stainless steel to reduce wear and prevent rust. Hardened, stabilized, ground, and lapped to +/- .0001". Supplied with storage case. The Micrometer Set Master has two odd steps at .512"and another at .712". These Steps allow checking of parallelism of the micrometer anvils. The micrometer masters are 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 because they replicate how the micrometer is used.
