Spi CMS160726108 Dial Test Indicator 0.5mm Vertical Nist

Product Description

The SPI CMS160726108 is a vertical-style dial test indicator designed for precision measurement tasks in machining, metrology, and quality inspection environments. With a maximum measurement range of 0.5 mm and a dial graduation of 0.010 mm, it delivers fine resolution suitable for runout checks, surface comparisons, and fixture setups. Accuracy is rated at 0.013 mm. The 32 mm white dial face uses a 0-25-0 bidirectional reading scale, making it straightforward to read both positive and negative deviation without repositioning the indicator. A 14.4 mm contact point with a 2 mm ball tip is included. The unit weighs 0.25 pounds and fits standard indicator holders and magnetic bases used in machine shop and inspection room applications.

This dial test indicator is suited for use in toolroom, production floor, and quality control settings where repeatable, fine-tolerance measurements are required. Typical applications include checking shaft runout, verifying surface parallelism, indicating workpieces into position on mills and lathes, and inspecting part geometry against dimensional tolerances. The vertical indicator style allows the contact point to sweep in line with the indicator body, which is useful when working in confined setups or along vertical surfaces. A NIST traceability certification is included, supporting use in documented quality systems and calibration programs.

Compatibility

Designed for use with standard dial indicator holders, dovetail clamps, and magnetic base systems commonly found in machine shop and inspection room environments.

Installation Notes

Dial test indicators are typically installed and used by machinists, tool and die makers, and metrology technicians. Mount the indicator securely in a compatible holder or clamp before use, and verify the contact point makes consistent contact with the measured surface at the correct angle to avoid cosine error. Handle the contact point and measuring tip carefully to avoid damage to the precision mechanism. Store the indicator in its case when not in use to protect the calibrated components.
