Mitutoyo 368-773 Mechanical Three-Point Internal Micrometer, 87-100mm

Mitutoyo, 368-773, Mechanical Holtest Three-Point Internal Micrometer, 87-100mm

Features:

• Design allows for measurements closer to the bottom of blind bore holes
• Scale on thimble and sleeve is laser etched for easier reading in all conditions

The Mitutoyo mechanical Holtest internal micrometer features three alloy steel anvils evenly spaced at 120° for true alignment of the axis bore for accurate, easily repeatable measurements. A hardened steel spindle with a carbide ball and cone with a carbide pin ensure accuracy and durability when extending and retracting the anvils. The holtest's ratchet stop mechanism provides a constant measuring force on the hardened-steel spindle to ensure accurate, even measurements.
