This versatile and self-centering 3 point internal micrometer are designed for accurate and repeatable measurement of internal diameter. Measurement can be taken closed to the bottom of a blind hole or in a deep hole with extension rod. 3 point anvils evenly spaced at 120 degree apart, contact the internal wall surface and find the true alignment with the bore axis for accurate ID measurement.
Calibration procedure:
