Today I found an interesting micrometer. You can plug a dial indicator on the left end. The left anvil is spring loaded. So it can be used in many ways. I noticed that many times I don’t care about absolute values, instead I want to know only if two diameters are precisely equal. With this thing I can compare parts over a wider range than a usual 25mm span micrometer.
I bought also one more 2μm dial indicator. I can’t help myself when I see one. The tip of this micrometer is transparent, like glass.
