It covers a measurement range of 2 inches to 2.5 inches with a graduation of 0.0002 inches and an accuracy of 0.0002 inches. The chrome-finished instrument features a ratchet stop thimble, three self-centering contact points, and carbide measuring surfaces for durability and repeatable readings. A NIST traceability certification is included, making it suitable for quality-controlled production floors and inspection departments. Machinists, metrologists, and precision manufacturing technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis hole micrometer is suited for measuring bores, cylinders, and inside diameters in the 2 inch to 2.5 inch range. It is appropriate for use in machine shops, toolrooms, and quality inspection settings where tight tolerances must be verified. The instrument includes one extension rod, which extends up to 6 inches, and a 2.5 inch setting ring for calibration. A gage depth of 4.49 inches supports access to deeper bore features. The three-point self-centering contact design helps achieve accurate, repeatable measurements without manual alignment correction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 2 inches to 2.5 inches with 0.0002 inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated at 0.0002 inches for precision inspection work\u003c\/li\u003e\n  \u003cli\u003eCarbide measuring surfaces resist wear over repeated use\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble provides consistent measuring pressure\u003c\/li\u003e\n  \u003cli\u003eThree self-centering contact points for accurate bore alignment\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certification included for quality-compliance applications\u003c\/li\u003e\n  \u003cli\u003eIncludes one extension rod and one 2.5 inch setting ring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for inside bore and hole measurement applications requiring a 2 inch to 2.5 inch range.
