INTERNAL MICROMETERS                                                           Schut for Precision

Mitutoyo Holtest two-point and three-point internal micrometers

  Two-point and three-point internal micrometers for quick and accurate measurement of internal
dimensions, within a large measuring range. These instruments have an improved ratchet mechanism
and the application of high-quality materials ensures a long life span.
