Mitutoyo 468-264 Electronic Inside Micrometer 0.5 to 0.65 in

Product Description

The MITUTOYO 468-264 is a three-contact electronic inside micrometer designed to measure internal bores and holes with high precision. It covers a measuring range of 0.5000 to 0.6500 inches and delivers a resolution of 0.00005 inches with an accuracy of 0.00010 inches. The instrument features a ratchet stop thimble for consistent measuring force and a large LCD display with 7.5 mm character height for easy reading in typical shop conditions. A titanium nitride finish provides durable surface protection. Data output capability allows direct connection to statistical process control systems or data loggers, making this micrometer suitable for quality inspection workflows.

The 468-264 is used in precision measurement applications across machine shops, manufacturing facilities, and inspection departments. It is well suited for measuring internal diameters of bearings, bushings, bores, and similar components where tight tolerances must be verified. The IP65 ingress protection rating means the instrument resists coolant spray and dust, making it appropriate for use at or near CNC machining centers and on the shop floor. Machinists, quality technicians, and metrologists are the primary users of this instrument.

Compatibility

Designed as an OEM-grade precision inside micrometer for use in standard bore measurement applications requiring the 0.5000 to 0.6500 inch range.

Installation Notes

This instrument does not require mechanical installation but should be handled and calibrated by a qualified machinist or metrology technician. Zero the micrometer using the supplied setting standard before use and verify calibration periodically against traceable gauge blocks or ring gauges. Keep the contact points clean and free of chips or coolant residue before measurement. Store the instrument in the included plastic case when not in use to protect the spindle and contact surfaces.
