Starrett 64465 Outside Micrometer Set 6 to 12 in 6 Pc

Product Description

The STARRETT 64465 is a 6-piece mechanical outside micrometer set covering a measurement range of 6 to 12 inches in 1-inch increments. Each micrometer features a ratchet stop thimble for consistent, repeatable measuring force and solid carbide measuring faces for long-term wear resistance. The satin chrome finish reduces glare during use. This set is designed for precision dimensional inspection work in machine shops, manufacturing facilities, and tool rooms where large-diameter external measurements are required. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of this type of equipment.

This set covers large-range external measurement applications from 6 inches through 12 inches, making it suited for measuring large shafts, bores, castings, and machined components. The included case keeps all six micrometers organized and protected during storage and transport. The set carries standards references 6, 7, 8, 9, 10, and 11, indicating conformance to recognized precision instrument standards. The Starrett catalog reference number for this set is ST436DXRLZ.

Compatibility

Designed as a large-range outside micrometer set for professional metrology and precision inspection applications requiring external measurements from 6 to 12 inches.

Installation Notes

Outside micrometers of this size range are calibrated instruments and should be handled by qualified machinists or metrology personnel. Before use, verify zero calibration with the appropriate setting standard for each 1-inch range. Store micrometers in the provided case away from temperature extremes and contaminants that can affect accuracy. Do not force the thimble; use only the ratchet stop to apply measuring pressure.
