The micrometer set master model 112 is available in both inches and millimeters.
The inch range is 1.00 to 12.00" in 1.00" increments . It is hardened, stabilized, ground and lapped to +/- .0001".
The metric range is 25.00 to 300.00mm in 25.00mm increments. It is hardened, stabilized, ground and lapped to +/- .0025mm.
Both are supplied in chrome plate 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 eliminate the requirement to stack gage blocks. Using micrometer masters is faster and more efficient for inspecting the linear range of the tool. Micrometer set masters indicate the wear on the micrometer anvil because they replicate how the micrometer is used.
