Mitutoyo 123-125 Mechanical Disk Micrometer 0-1 Inch .001 Inch Resolution

The Mitutoyo 123-125 is a precision mechanical disk micrometer designed for measuring hard-to-reach features like groove diameters, keyways, and narrow slots in shafts and other components. With a measuring range of 0-1 inch and .001 inch resolution, this instrument delivers accurate measurements in confined spaces where standard micrometers cannot reach.

Key Features:

• 0-1 inch measuring range with .001 inch graduation for precise readings
• .787 inch (20mm) diameter disk with .028 inch (0.7mm) edge thickness for accessing narrow grooves and slots
• Ratchet stop mechanism ensures consistent measuring force for repeatable results
• Spindle and anvil feature carbide measuring faces for durability and wear resistance
• Supplied in fitted plastic storage case for protection and organization

The thin disk design makes this micrometer ideal for quality control and inspection applications in manufacturing environments where measuring internal groove dimensions is critical. The ratchet stop prevents over-tightening and ensures uniform pressure during measurements, reducing operator variability and improving measurement consistency.
