Spi CMS160725091 Dial Drop Indicator 10mm 0.01mm Grad

Product Description

The SPI CMS160725091 is a dial drop indicator designed for precision dimensional measurement in machine shop, toolroom, and quality control environments. It covers a 10mm measurement range with 0.01mm graduation increments and delivers 0.02mm accuracy across that range. The 58mm white dial face offers clear readability, and a built-in revolution counter tracks full spindle rotations to prevent misreading cumulative displacement. A lug-back mount and universal positioning capability allow flexible fixture setup on magnetic bases and surface plates. This instrument is used by machinists, metrologists, and quality technicians who need repeatable, traceable linear measurement results.

The CMS160725091 is suited for surface runout inspection, part flatness checks, fixture alignment, and comparative gauging tasks in both production and toolroom settings. The 8mm stem diameter is compatible with standard indicator holders and magnetic base clamps. The included NIST Traceability Certification supports use in environments requiring documented calibration records, such as ISO-compliant shops and aerospace or automotive quality systems.

Key Features

• 10mm total measurement range with 0.01mm dial graduation for fine-resolution readings
• 0.02mm accuracy per US Federal Specifications and NIST standards
• 58mm white dial face with 0-100 dial reading scale and revolution counter pointer
• Lug-back mount with universal positioning capability for versatile fixture setups
• 8mm stem diameter fits standard indicator holders and magnetic base clamps
• Includes NIST Traceability Certification for use in ISO-compliant quality systems

Compatibility

Designed for use with standard indicator holders, magnetic bases, and surface plate setups that accept an 8mm stem diameter drop indicator. Thread size compatibility: No. 4-48 and M2.5.

Installation Notes

Mounting and setup should be performed by a qualified machinist or metrology technician familiar with indicator fixture practices. Secure the lug back or stem firmly in the holder before zeroing the dial to prevent slippage during measurement. Avoid lateral loading on the spindle, as side forces can introduce measurement error and accelerate wear. Zero the indicator at the reference datum point before recording measurements, and verify calibration status against the NIST certificate prior to use in critical inspection applications.
