Spi CMS160714033 Dial Drop Indicator 0.001 in

Product Description

The SPI CMS160714033 is a dial drop indicator designed for precise linear measurement in machining, inspection, and quality control applications. It features a 0.25-inch total measurement range with 0.001-inch graduation increments, allowing technicians to detect very small surface variations or part deviations. The 1.61-inch white dial face displays a 0-100 reading scale for easy interpretation at a glance. A NIST Traceability Certification is included, making this indicator suitable for use in environments where documented measurement standards are required. Machinists, tool and die specialists, and quality control inspectors are the primary users of this instrument.

This dial drop indicator is well suited for setup and inspection tasks on manual mills, lathes, surface plates, and CMM fixtures in both shop floor and laboratory environments. Its lug-back mount and 3/8-inch stem diameter allow it to seat in standard indicator holders and magnetic bases commonly found in machine shops. The counter pointer and universal positioning capability make it adaptable across a wide range of measuring setups. It is equally at home in production inspection lines and one-off toolroom work.

Key Features

• 0.25-inch total range with 0.001-inch graduation for fine linear measurement
• 1.61-inch white dial face with 0-100 reading scale for clear readability
• 0.1-inch range per revolution for controlled, repeatable traversal
• Lug back mount with 3/8-inch stem diameter fits standard indicator holders
• NIST Traceability Certification included for documented measurement compliance
• Counter pointer and universal positioning capability for versatile setups

Compatibility

Designed as a standard AGD Group 1 dial drop indicator compatible with common lug-back indicator holders, magnetic bases, and 3/8-inch stem clamps used in machine shop and inspection environments.

Installation Notes

A licensed machinist or quality control technician should mount this indicator using a clean, secure holder to prevent vibration-induced reading errors. Ensure the spindle axis is aligned perpendicular to the measured surface to avoid cosine error. Do not overtighten the stem clamp, as this can affect spindle travel and accuracy. Handle the dial face and spindle with care to preserve calibration integrity.
