Fowler 52-710-030 Dial Test Indicator Kit 9 Pc

Product Description

The FOWLER 52-710-030 is a 9-piece dial test indicator kit designed for precision measurement in centering, positioning, and alignment work. The kit centers on a dial test indicator with a 0-5-0 reading dial, an accuracy of 0.0002 inches (0.0050 mm), and a white and yellow dial face 42.5 mm in diameter. The 2D coaxial design and included restraining arm provide stable, repeatable contact during measurement. Machinists, toolmakers, and metrologists use this kit when setting up fixtures, indicating bores, or checking runout on machine tools and inspection equipment.

This kit suits precision machining and inspection environments where dial test indicators are required for centering and positioning operations. The 0-5-0 dial reading format makes bidirectional deviation easy to read at a glance. With a ball diameter of 0.130 inches (3.0 mm) and a range of 6.0 mm per revolution, the indicator handles fine-tolerance work across a range of contact points provided by the included feeler set.

Key Features

• Accuracy of 0.0002 inches (0.0050 mm) for fine-tolerance measurement
• 0-5-0 dial reading format supports bidirectional deviation readout
• 2D coaxial design for centering and positioning applications
• Includes 6 feelers, a center point feeler, a gage, and a restraining arm
• Ball diameter of 0.130 inches (3.0 mm) for consistent contact
• White and yellow dial face, 42.5 mm diameter, for clear readability

Compatibility

Designed as a standard dial test indicator kit suitable for use with indicator holders, magnetic bases, and surface plates common in machine shop and inspection setups.

Installation Notes

Dial test indicators are typically set up by machinists and tool and die technicians using magnetic bases, indicator holders, or dovetail-mount arms. Before mounting, ensure the spindle or fixture is stationary and the machine is powered down or locked out as required. Avoid side-loading the indicator contact point beyond the specified range per revolution, as this can affect accuracy and damage the mechanism. Handle the feeler tips with care to prevent nicks or contamination that would affect measurement results.
