For the measurement of the inner diameter of drills for example inside micrometers can be used.
They exist as 2-point of 3-point inside micrometer.
The advantage of 3-point-inside micrometer is its selfcentering.
Inside micrometers cannot be used for measuring roundness.
There are point and line measuring surfaces as well as the special case of beak measuring surfaces.
