Mitutoyo Type II Hall Test 3-Point Inner Micrometer

The Mitutoyo HT2-16R Point Inner Micrometer 12-16 mm Measuring Range 6957352 is a specialized precision measuring instrument primarily utilized for gauging the internal dimensions of deep and narrow cylindrical bores. Its application is widespread in industries such as manufacturing, automotive, aerospace, and engineering, where accurate measurements of internal bores are crucial for ensuring component quality and precise fits. The point inner micrometer is designed with a slender tubular structure, housing a measuring spindle that is guided within the tube. At the end of the spindle, a small, rounded measuring point is affixed, enabling it to reach deep into confined spaces to make contact with the bore's inner surface. The opposite end of the tubular micrometer features a ratchet or thimble mechanism that precisely advances the spindle forward, causing the measuring point to expand gently and make contact with the bore walls. This measuring instrument often comes with interchangeable measuring anvils or points, allowing for versatility in accommodating various bore sizes and shapes. Moreover, the micrometer's scale is finely graduated, enabling readings to be taken with high precision. The point inner micrometer requires careful handling and delicate usage to maintain accuracy and prevent damage to the measuring point and internal components. Regular calibration against traceable standards is essential to verify measurement accuracy and ensure conformity to specified tolerances.
