Mitutoyo 103-906 Outside Micrometer Set 6-12 in 6 Pc

Product Description

The MITUTOYO 103-906 is a 6-piece mechanical outside micrometer set covering a measurement range of 6 to 12 inches. Each micrometer in the set uses a ratchet stop thimble for consistent measuring force and features solid carbide measuring faces for durability and wear resistance. Accuracy is rated at 0.0002 inches for the 6 to 9 inch range and 0.00025 inches for the 9 to 12 inch range. The frames carry a baked enamel finish. This set is used by machinists, tool and die technicians, and precision measurement professionals working with large-diameter workpieces.

This micrometer set is suited for precision inspection and layout work in machine shops, manufacturing facilities, and tool rooms where large outside diameter measurements are required. The 6-piece configuration covers incremental ranges from 6 inches through 12 inches, allowing a single set to handle a broad span of workpiece sizes without swapping instruments. Each unit ships with a setting standard, certificate of inspection, and key, supporting traceable calibration workflows in quality-controlled environments.

Compatibility

Designed as an OEM-style precision measuring instrument set for general outside diameter measurement applications in the 6 to 12 inch range, suitable for use in machine shop, manufacturing, and quality inspection environments.

Installation Notes

Outside micrometers require calibration verification against the included setting standards before use, particularly after transport or storage. Always zero or verify the instrument at the appropriate setting standard before taking measurements. Micrometers should be stored in their case away from heat sources and direct contact with other tools to protect the measuring faces and spindle threads. Cleaning the measuring faces with a lint-free cloth before use is standard practice to prevent contamination errors.
