Fowler 52-710-025-0 Dial Test Indicator Kit 7 Piece

Product Description

The FOWLER 52-710-025-0 is a 7-piece dial test indicator kit designed for precision measurement in centering, positioning, and coaxial alignment tasks. The kit delivers a measuring range of 0.25 inches with a dial graduation of 0.0005 inches and an accuracy of 0.0002 inches, making it suitable for close-tolerance inspection work on machine tools, fixtures, and workholding setups. The 1.6-inch diameter white dial reads 0-5-0 for bidirectional measurement. This kit is used by machinists, tool-and-die makers, and precision measurement technicians who require a compact, repeatable indicator with accessories for varied setups.

This dial test indicator kit fits into general-purpose metrology workflows in machine shops, manufacturing facilities, and maintenance environments. The 2D coaxial design supports both centering bores and positioning workpieces on milling machines, lathes, and surface plates. The included restraining arm and multiple feeler options allow the indicator to be positioned at varied angles without losing contact geometry. The kit is appropriate for inspection applications where a full 1-inch travel indicator is too large or impractical.

Key Features

• 0.25-inch measuring range with 0-5-0 bidirectional dial reading
• 0.0002-inch accuracy and 0.0005-inch dial graduation for fine-tolerance work
• 2D coaxial design supports centering and positioning applications
• 1.6-inch diameter white dial for clear readability
• Includes 3 curved feelers, center point feeler, coaxial indicator, restraining arm, and carrying case
• 0.130-inch ball diameter on contact point feelers

Compatibility

Designed as a general-purpose dial test indicator kit compatible with standard indicator holders, magnetic bases, and dovetail-style mounting arms commonly used in machine shop and inspection setups.

Installation Notes

Mount the indicator using the included restraining arm or a compatible magnetic base or indicator holder. Secure all clamping hardware before zeroing the dial to prevent drift during measurement. Select the appropriate feeler tip for the contact geometry of the workpiece. Handle contact points and feeler arms carefully to avoid bending, which can introduce measurement error.
