Mitutoyo, 368-768, Mechanical Holtest 3-Point Internal 30-40mm Micrometer

Features:

• The design allows for measurements closer to the bottom of blind bore holes
• The scale on the thimble and sleeve is laser etched for easier reading in all conditions
• Supplied in a fitted plastic case

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.
