    Coolant-Resistant Digital Calipers

    Image of Product. Front orientation. Calipers. Coolant-Resistant Digital Calipers.
    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 calipers give instant measurements—no need to count graduations. 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 of these calipers is made within Mitutoyo's automated system and tested in-house in Japan. Their jaws are laser cut to exact dimensions for the most reliable measurements.
    Starrett—Starrett calipers come packaged in their iconic wood or red plastic case, so you'll be able to spot them on the busiest of bench tops.
    McMaster-Carr Approved—The performance of brand-name calipers 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 calipers 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.
    Carbon Fiber Body—Despite their large size, these calipers are light enough to comfortably carry around the job.

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.

    Keep a collection of digital micrometers handy to measure parts of different sizes. These micrometers come in a convenient case to store and organize them in one place. They're a must-have for machine shops—each display and battery cover is 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.

    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.

    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.

    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.
