Starrett 52930 Dial Test Indicator 0.70mm Horizontal

Product Description

The STARRETT 52930 is a horizontal-style dial test indicator designed for precise dimensional measurement in machining, inspection, and metrology applications. It reads on a 0-35-0 balanced dial with a 0.01 mm graduation and a full range of 0.70 mm per revolution. The 15/16-inch diameter white dial provides clear, easy readability under shop conditions. Built around a jeweled lever action mechanism and equipped with a hard chrome-plated contact point, this indicator delivers repeatable, reliable readings. It includes a positive reversing switch for bidirectional measurement and a swiveling tubular body for flexible positioning on a variety of fixtures and setups.

The 52930 is suited for machine shop and quality control environments where compact size and accurate deviation readings matter. The horizontal style makes it practical for surface plate work, fixture verification, runout checks, and part-to-part comparison measurements. The small form factor and swiveling body allow placement in tight clearance situations where a standard plunger-type indicator would not fit. One contact point is included. The body clamp included with the unit simplifies mounting to indicator holders and magnetic bases.

Key Features

• 0.70 mm measurement range per revolution with 0.01 mm graduations for fine resolution
• 0-35-0 balanced dial reading supports bidirectional deviation measurement
• Jeweled lever action reduces friction and wear for consistent, long-service accuracy
• Hard chrome-plated contact point resists wear in abrasive shop environments
• Positive reversing switch allows bidirectional stylus travel without re-zeroing the dial
• Swiveling tubular body enables precise positioning and angle adjustment on fixtures
• White dial face with easy-reading graduations for clear visibility in shop lighting

Compatibility

Part of the STARRETT 711 Series dial test indicators. Designed as a direct-fit replacement or supplement within that series. One contact point with a 3.97 mm length and a 3.00 mm diameter ball tip is included. Confirm stylus thread compatibility before substituting aftermarket contact points.

Installation Notes

Dial test indicators of this type are installed and serviced by machinists, toolmakers, and quality technicians. Mount the swiveling tubular body securely in a compatible indicator holder, arm clamp, or magnetic base before use. Do not overtighten clamping hardware against the tubular body, as excess force can affect calibration and internal mechanism alignment. Verify zero and stylus preload direction before recording measurements.
