Fowler 52-229-770-0 Dial Test Indicator Kit 9 Pc

Product Description

The FOWLER 52-229-770-0 is a 9-piece dial test indicator kit designed for precision measurement in machine shops, toolrooms, and manufacturing environments. The kit centers on a dial test indicator with a 0.03 inch measuring range and a 0-100 black dial reading with 0.0005 inch graduations. Three interchangeable ball-style contact points in 0.04, 0.08, and 0.12 inch diameters allow the technician to adapt to different workpiece geometries. All components store in a shop-hardened case built to withstand daily bench and floor use. Machinists, tool and die makers, and quality control technicians are the primary users of this kit.

This kit is suited for residential and commercial machine shop applications where runout, surface flatness, alignment, and bore concentricity checks are required. The included caliper and outside micrometer extend the kit beyond indicator work, making it a compact multi-gauge solution for setup and inspection tasks. The shop-hardened case keeps everything organized and protected during transport between workstations or job sites. Technicians setting up CNC fixtures, checking spindle runout, or verifying workholding alignment will find the combination of indicator, contact points, dovetail stems, caliper, and micrometer in a single kit particularly useful.

Key Features

• Dial test indicator with 0.03 inch total measuring range and 0.0005 inch dial graduation
• Three contact point ball diameters: 0.04 inch, 0.08 inch, and 0.12 inch for versatile workpiece access
• Two dovetail stems included for mounting compatibility with standard indicator holders and magnetic bases
• Kit includes caliper and outside micrometer for extended measurement coverage
• Black 0-100 dial face for high-contrast reading under shop lighting
• Shop-hardened case protects all components during storage and transport

Compatibility

Designed as a self-contained dial test indicator kit compatible with standard dovetail-style indicator holders and magnetic base mounting systems commonly used in machine shop and toolroom setups.

Installation Notes

Dial test indicators are installed by machinists and quality control technicians using magnetic bases, surface gauge arms, or dedicated indicator holders. Before mounting, ensure the workpiece or machine spindle is fully stopped and all motion is locked out. Secure the dovetail stem firmly in the holder to prevent indicator creep during measurement. Avoid side-loading the indicator tip beyond its rated travel range, as this can damage the internal gear train.
