    Coolant-Resistant Digital Outside Micrometers

    Image of Product. Front orientation. Outside Micrometers. Coolant-Resistant Digital Outside Micrometers.
    Measure parts inside CNC machines and other places coated with coolant and cutting oil. The display and battery cover are tightly sealed, so spraying and dripping fluids won't seep in.
    With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.
    Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.
    Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.
    Ratchet Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.
