    Performance

    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.
    McMaster-Carr Approved—The performance of brand-name micrometers without the cost.
    With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.
    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.
    Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.
    Ratchet Thimble/Ratchet-Stop 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.

    Digital Outside Micrometers for Curved and Flat Surfaces

    Image of Product. Front orientation. Outside Micrometers. Digital Outside Micrometers for Curved and Flat Surfaces.
    Swap between two anvils to view curved and flat surface measurements with the same screen. The straight anvil sits against flat surfaces without wiggling. The round anvil hugs curved surfaces, so you don't measure a gap.
    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.

    Coolant-Resistant Wide-Range Digital Outside Micrometers

    Image of Product. Front orientation. Outside Micrometers. Coolant-Resistant Wide-Range Digital Outside Micrometers.
    Check different-sized parts as you machine them without swapping between tools. These micrometers come with multiple anvils that you switch out, so you don't need to lug around a case of micrometers. Whether you're milling or drilling, the display and battery cover are tightly sealed, so spraying and dripping coolant 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.
    With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.
    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-Stop 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.

    Outside Micrometers for Tolerance Checking

    Dial Display

    Confirm parts are within tolerance without twisting the thimble each time. These micrometers don't need batteries, so they're always ready for the job.
    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.
    Dial Display—Know exactly how far your part falls outside of the tolerance range. Push a button to retract the anvil, then slide your part in. Release and the anvil snaps back to its set position. The needle on the dial shows you the difference in measurement.

    Coolant-Resistant Long-Reach Digital Outside Micrometers

    Image of Product. Front orientation. Outside Micrometers. Coolant-Resistant Long-Reach Digital Outside Micrometers.
    Take thickness measurements of sheet metal and other long, flat parts right inside CNC machines. The display and battery cover are tightly sealed, so spraying and dripping coolant won't seep in. These micrometers have a deep throat to reach the center of workpieces, away from the edge where deformities might skew readings.
    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.
    With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.
    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-Stop 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.

    Take measurements with either hand, upside down, or right side up. You can read a display from either side of these micrometers and push a button to invert the text when measuring overhead. They're especially handy for hard-to-move parts, such as heavy steel plates.
    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.
    McMaster-Carr Approved—The performance of brand-name micrometers without the cost.
    Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.
