Starrett T444.1XRL-2 Outside Micrometer 2 in Range

Product Description

The STARRETT T444.1XRL-2 is a mechanical outside micrometer designed for precision linear measurement in machining, fabrication, and quality-control applications. It covers a measurement range up to 2 inches with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for tight-tolerance work where reliable, repeatable readings are critical. The satin chrome finish reduces glare and corrosion. A ratchet stop thimble controls measuring force, and the rotating spindle and ring-style lock nut allow for secure, consistent measurements. Solid carbide measuring faces resist wear during frequent use. The unit ships with a protective case and wrench.

This micrometer is used in machine shops, toolrooms, and general metalworking environments where outside dimensions of parts must be verified to four decimal places. It is well suited for machinists, quality technicians, and precision fabricators working on shafts, pins, stock material, and similar components that require accurate outside diameter or thickness measurements within the 2-inch range.

Key Features

• Measurement range up to 2 inches with 0.0001 inch graduation
• Accuracy rated at 0.0001 inches for tight-tolerance applications
• Ratchet stop thimble provides consistent, repeatable measuring force
• Solid carbide measuring faces for extended wear resistance
• Ring-style lock nut secures the spindle at a fixed reading
• Satin chrome finish reduces glare and resists corrosion
• Includes protective case and wrench

Compatibility

Designed as a standard mechanical outside micrometer suitable for general precision measurement tasks requiring a 0 to 2 inch measuring range in machining and inspection applications.

Installation Notes

Outside micrometers require no installation, but should be calibrated or zeroed using the included wrench and reference standard before use. Store the instrument in its case when not in use to protect the measuring faces and maintain accuracy. Avoid dropping or applying excessive force to the frame, as this can affect calibration and flatness of the anvil and spindle faces.
