Is there more than one kind of micrometer? Yes, there are many kinds of micrometers out there. Some are basic micrometers, while others are specialized micrometers for particular jobs or measurements. What makes each micrometer unique is the kind of measurement purpose it serves. Universal micrometers are built with parts that can be swapped out depending on the job at hand. Blade micrometers, pitch-diameter micrometers, bore micrometers, tube micrometers, and bail micrometers are just few examples of micrometers with specialized parts that identify them for particular measurement goals. Digit micrometers use mechanical digit markers that roll and tell the measurement, whereas digital micrometers have an internal encoder that reports the measurement on a readable screen.
