Mitutoyo 123-125 Mechanical Disc Micrometer 0-1 in

Product Description

The MITUTOYO 123-125 is a mechanical disc micrometer designed for precision measurement of thin or narrow workpieces where a standard flat anvil cannot make reliable contact. It covers a measurement range of 0 to 1 inch with a graduation of 0.001 inch and an accuracy of 0.0002 inch. The 20 mm disc and 0.70 mm disc edge allow access to grooves, lands, and recessed features that standard micrometers cannot reach. A ratchet stop thimble provides consistent measuring force, reducing operator-to-operator variation. Steel anvil and spindle surfaces resist wear under regular shop use. This tool is used by machinists, quality control technicians, and precision measurement professionals.

The 123-125 is suited for dimensional inspection in machine shops, manufacturing facilities, and quality labs. Its rotating spindle and 20 mm disc make it effective for measuring pitch diameters, disc thicknesses, grooves, and similar features on turned or milled components. The satin chrome finish reduces glare under shop lighting. With an IP65 water resistance rating, it holds up in environments where coolant splash is a routine concern. The included plastic case protects the instrument during storage and transport.

Compatibility

Designed as an OEM-style precision measurement instrument suitable for general dimensional inspection of grooves, lands, and thin disc features in machining and manufacturing applications.

Installation Notes

Disc micrometers are handled and calibrated by metrology technicians or qualified machinists. Before use, verify the zero setting against a known standard or gauge block per your facility calibration procedure. Protect the disc faces and spindle from impact and debris when not in use. Store in the included plastic case to maintain calibration and protect the satin chrome surfaces.
