Spi CMS220519033 V-anvil Micrometer 0-0.60 in Electronic

Product Description

The SPI CMS220519033 is an electronic V-anvil micrometer designed for precision measurement of taps, reamers, end mills, and other three-fluted or five-fluted cutting tools. It measures from 0 to 0.60 inches with a resolution and graduation of 0.0001 inches, making it suitable for applications where tight dimensional tolerances are required. The ratchet thimble delivers consistent measuring pressure across readings, and the carbide anvil material extends service life under repeated shop-floor use. A positive lock nut holds the spindle position during readout. Data output capability allows integration with SPC systems or digital readout stations. Installed and used by machinists, tool-and-die makers, and quality control technicians.

This micrometer is used in machine shops, tool rooms, and manufacturing quality control environments where cutting tool geometry must be verified before and after grinding operations. The electronic readout eliminates interpolation error common with vernier-style instruments. The V-anvil geometry seats directly on the cutting tool flutes to measure the true outside diameter across the lands. It ships in a plastic storage box suitable for bench or toolbox storage in production and inspection settings.

Key Features

• Electronic operation with 0.0001 inch graduation and resolution for high-accuracy readings
• V-anvil design seats on three-fluted or five-fluted cutting tools for true OD measurement
• Carbide anvil material resists wear during repeated contact with hardened tool surfaces
• Ratchet thimble ensures repeatable, consistent measuring force
• Positive lock nut secures spindle position for stable readout and transfer measurements
• Data output port supports SPC and digital recording integration
• Calibrated and meets ASME 89.1.13 standard

Compatibility

Designed for OD measurement of three-fluted and five-fluted cutting tools including taps, reamers, and end mills within a 0 to 0.60 inch measurement range.

Installation Notes

This instrument requires no installation — it is a handheld precision measuring tool used at the bench or inspection station. Handle with clean, dry hands or cotton gloves to prevent thermal expansion error from skin contact. Before use, verify calibration against a known standard and clean anvil and spindle faces with a lint-free cloth. Store in the included plastic box when not in use to protect the carbide anvil and electronic components.
