Mitutoyo 513-504-10T Dial Test Indicator 0.01 in

Product Description

The MITUTOYO 513-504-10T is a horizontal-style dial test indicator designed for precise surface measurement, runout inspection, and workpiece alignment in machine shop and metrology environments. It features a 0-5-0 white dial with a range of 0.01 inches per revolution and an accuracy of 0.0002 inches, with graduations at 0.0001 inches. The jeweled bearing assembly supports repeatable, low-friction stylus movement. A dovetail mount provides rigid, stable attachment to indicator holders and magnetic bases. The unit ships with two contact points, a holding rod, an inch holding bar, a stem, and a swivel clamp, making it ready for immediate use. Machinists, tool and die technicians, and quality control inspectors are the primary users.

The 513-504-10T suits horizontal-access measurement tasks where a contact point must approach a surface from the side rather than from above. Typical applications include checking spindle runout on lathes and mills, verifying concentricity, inspecting part flatness, and setting up fixtures. The 220-degree contact point swivel angle allows the stylus to reach into confined areas. The carbide-tipped contact points resist wear during high-cycle inspection routines. The O-ring seal and dust and oil proof construction make it suitable for use directly on the machine tool, where coolant and particulate exposure are common.

Key Features

• 0.01 inch total range per revolution with 0.0001 inch dial graduations
• 0.0002 inch accuracy for tight-tolerance inspection work
• Jeweled bearing construction supports smooth, repeatable stylus actuation
• 220-degree contact point swivel angle for access to confined measurement locations
• Carbide-tipped contact points included for extended service life
• O-ring seal with dust and oil proof housing for direct machine-side use
• Automatic reversal and no-clutch structure reduce wear and simplify operation

Compatibility

Designed for use with standard dovetail-mount indicator holders, arms, and swivel clamps. Compatible with universal dial indicator stands and magnetic base systems that accept dovetail-style indicators. Two contact points are included; additional contact points with a 2.00 mm ball diameter and 0.70 inch length are the correct replacement specification.

Installation Notes

Installation is performed by machinists or metrology technicians using the included swivel clamp and dovetail mount. Power down and secure any rotating spindle before mounting or repositioning the indicator. Tighten the clamp only enough to prevent movement during measurement — overtightening can distort the dovetail and affect repeatability. Verify stylus preload and zero the dial before taking readings, following standard metrology practice.
