Spi CMS160809048 Interchangeable Anvil Micrometer 6 in

Product Description

The SPI CMS160809048 is a mechanical interchangeable anvil micrometer with a 6-inch measurement range and a set of 6 solid carbide anvils. It delivers an accuracy of 0.0002 inches and a graduation of 0.0001 inches, making it suited for high-precision dimensional measurement in tool rooms, machine shops, and fabrication environments. The ratchet stop thimble provides consistent measuring pressure, and the rotating spindle allows for smooth, repeatable readings. The unit ships calibrated with NIST traceability documentation included. Machinists, quality technicians, and precision metrology professionals are the primary users of this instrument.

This micrometer is designed for applications that require measuring a wide range of outside dimensions with a single frame and interchangeable anvil set. The 6-anvil configuration covers the full 6-inch range in increments, making it practical for production inspection, incoming material verification, and layout work. It is well suited for both shop-floor use and controlled metrology environments where NIST-traceable calibration is required for quality system compliance.

• Mechanical operation with no battery or data output dependency

Compatibility

Designed as a standard interchangeable anvil outside micrometer suitable for general precision measurement applications across manufacturing, tooling, and inspection disciplines. No specific system or equipment compatibility is stated in the product data.

Installation Notes

This instrument is handled and maintained by machinists, metrologists, and quality control technicians. Store anvils in the provided case to prevent damage to the solid carbide measuring faces. Allow the micrometer and workpiece to reach the same ambient temperature before measuring to avoid thermal expansion error. Do not apply excessive force when seating anvils or advancing the spindle; use the ratchet stop for all final measurements.
