Spi CMS160714022 Dial Drop Indicator 0.05in 0.0001in Grad

Product Description

The SPI CMS160714022 is a dial drop indicator designed for high-precision dimensional measurement in machining, toolroom, and metrology applications. It covers a total range of 0.05 inches with a dial graduation of 0.0001 inches, allowing technicians to detect minute surface variation or part deviation. Accuracy is rated at 0.0007 inches. The 2.2-inch white dial face offers a 0-10 reading scale with a revolution counter for easy tracking across multiple rotations. A NIST Traceability Certification is included, making it suitable for quality-controlled environments that require documented calibration standards.

This indicator is used in precision measurement tasks such as checking runout, surface flatness, part alignment, and fixture setup on manual and CNC machine tools. The flat back and 3/8-inch stem diameter allow it to mount in standard magnetic base holders and indicator arms. The universal positioning capability makes it adaptable to a wide range of setups on the shop floor, inspection table, or lathe. It is typically installed and used by machinists, tool and die makers, metrology technicians, and quality control inspectors.

Key Features

• 0.05 inch total measuring range with 0.0001 inch graduation for high-resolution readings
• 0.0007 inch accuracy rating meets US Federal Specifications and NIST standards
• Revolution counter pointer tracks cumulative travel across the full range
• 2.2-inch white dial face with 0-10 reading scale for easy readability
• Flat back and 3/8-inch stem diameter fit standard magnetic base and indicator holders
• NIST Traceability Certification included for quality-controlled and documented inspection environments

Compatibility

Designed for use with standard indicator holders, magnetic bases, and transfer stands that accept a 3/8-inch stem diameter. Thread size is 4-48 and M2.5, compatible with common indicator contact point accessories.

Installation Notes

Mount the indicator in a rigid holder or magnetic base before zeroing the dial. Secure the stem clamp firmly to eliminate play without overtightening against the stem. Power down or lock out any machine spindle before setting up the indicator for runout or alignment checks. Contact points should be confirmed finger-tight and verified for stem thread compatibility before use.
