Mitutoyo 511-756-20 Dial Bore Gage 10 to 16 in 5 Anvil

Product Description

The MITUTOYO 511-756-20 is a dial bore gage designed to measure internal bore diameters from 10 to 16 inches with an accuracy of 0.000080 inches. It uses a two-point contact system and a pendulum guide structure that allows smooth slide movement during measurement. The gage ships with five anvils and includes a dial indicator, giving technicians the tooling needed for immediate use. Machinists, quality control technicians, and precision measurement professionals use this instrument to detect out-of-round conditions and taper inside bored cylinders, bearing housings, and similar precision components.

This gage is suited for inspection work in machine shops, manufacturing facilities, and precision maintenance environments where bore geometry must be verified to tight tolerances. The 10 to 16 inch measurement range covers large-bore applications such as industrial cylinder liners, pump housings, and heavy equipment components. The ovalness and taper measurement capability makes it useful wherever bore condition assessment is required beyond simple diameter confirmation.

• Two-point contact system ensures repeatable and consistent readings
• Pendulum guide structure allows smooth gage slide movement inside the bore
• Capable of detecting ovalness and taper conditions in a single setup
• Includes dial indicator and five anvils for ready-to-use deployment

Compatibility

Designed as an OEM-style precision measurement instrument for large internal bore gauging applications across industrial and machining environments.

Installation Notes

This instrument is used by machinists and quality technicians and does not require installation in the traditional sense. Before use, zero the gage using a calibrated ring gage or setting master of the appropriate diameter. Handle the dial indicator and anvil contacts with care to avoid impact that could affect calibration. Store the gage in its protective case when not in use to prevent damage to the contact points and indicator mechanism.
