Mitutoyo 102-718 Outside Micrometer 2 in 0.0001 Grad

Product Description

The MITUTOYO 102-718 is a mechanical outside micrometer designed for high-precision linear measurement in machining, fabrication, and inspection environments. It covers a measurement range of 0 to 2 inches with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for applications that demand tight tolerances. The thimble uses a ratchet stop mechanism to ensure consistent measuring force across repeated readings. Solid carbide measuring faces resist wear on both the anvil and the spindle contact surface. A heat-insulating frame reduces measurement error caused by heat transfer from the operator's hands during extended use. Machinists, tool and die technicians, and quality control inspectors are the primary users.

The 102-718 is well suited for precision measurement work in machine shops, manufacturing facilities, and quality assurance settings. Its 2-inch range makes it a practical choice for measuring shafts, pins, stock material, and machined parts that fall within that span. The ratchet stop thimble provides repeatable spindle pressure, which is especially useful when multiple technicians take measurements on the same workpiece or when comparing readings across a production run. The heat-insulating frame is particularly beneficial during extended inspection sessions.

Key Features

• 0 to 2 inch measurement range with 0.0001 inch graduation
• Accuracy of 0.0001 inches for high-tolerance inspection work
• Ratchet stop thimble ensures consistent, repeatable measuring force
• Solid carbide anvil and spindle measuring faces for extended wear resistance
• Heat-insulating frame minimizes thermal expansion error from hand contact
• Includes plastic storage case and standard reference bar

Compatibility

Designed as a standard mechanical outside micrometer for general-purpose precision measurement; compatible with any application requiring a 0 to 2 inch outside measurement range using inch-graduation tooling.

Installation Notes

Outside micrometers require calibration verification before use; check against the included standard bar and zero the instrument per the manufacturer's procedure. Store in the provided plastic case when not in use to protect the measuring faces and maintain calibration. Handle by the heat-insulating frame to minimize thermal effects on readings. Cleaning the anvil and spindle faces before each measurement session helps prevent debris-related inaccuracy.
