Spi CMS160713011 Dial Bore Gage 6 Inch 11 Anvil

Product Description

The SPI CMS160713011 is a dial bore gage designed for measuring internal bore diameters with a 6-inch diameter range and 11-anvil configuration. Built with carbide ball anvils, it delivers repeatable contact and extended wear resistance in demanding shop environments. The white dial face provides clear readout, and the unit includes an indicator. Accuracy is rated at 0.000650 inches, making it suitable for precision bore inspection work in machining, engine rebuilding, and mechanical assembly applications. Licensed machinists, engine rebuilders, and precision measurement technicians are the primary users of this instrument.

This dial bore gage fits into workflows where internal diameter measurement is required across multiple bore sizes using interchangeable anvils. The 11-anvil set expands the usable measurement range without requiring a separate tool for each bore size. It is well suited for production floor use, repair shop inspection stations, and quality control checks on machined components. The carbide ball contact points resist wear from repeated use on hardened or abrasive bore surfaces.

Key Features

• 6-inch diameter range with 11 interchangeable carbide ball anvils for broad measurement coverage
• Carbide ball anvil material provides wear resistance on hardened bore surfaces
• White dial face for clear, high-contrast readout in shop lighting conditions
• Indicator included — no separate purchase required for immediate use
• Accuracy rated at 0.000650 inches for precision internal diameter inspection

Compatibility

Designed as a direct-use precision measurement instrument for internal bore inspection; compatible with standard dial indicator bore gage setups requiring a 6-inch diameter range and 11-anvil configuration.

Installation Notes

Setup and calibration should be performed by a qualified machinist or metrologist familiar with dial bore gage procedures. Zero the gage against a calibrated ring gage or micrometer setting standard of known diameter before taking measurements. Handle carbide anvils with care to avoid chipping against hard surfaces. Store the instrument in its protective case when not in use to preserve accuracy.
