    Mitutoyo Depth Micrometers

    Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.

    Gauge

    Gauge with Hook End

    These gauges have two scales for fine adjusting—a main scale and a sliding vernier scale. The vernier scale takes the space between graduation marks on the main scale and divides them into smaller increments for an accurate depth reading. Use the adjustment screw on the vernier scale for fine tuning. Designed for durability, these analog gauges are good for measuring the depth of small holes and slots in machine shops where they’ll get frequent use. They are often used to set the cutting depth for milling tools and counterbores.
    Hook End—Gauges with a hook end can measure the depth of lips, grooves, and other projected or recessed features that a gauge with a straight end could not access.

    Mitutoyo Depth Micrometers with Calibration Certificate

    Image of Product. Front orientation. Depth Micrometers. Mitutoyo.
    These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.
