Mitutoyo 513-473-10E Dial Test Indicator 0.0001 in

Product Description

The MITUTOYO 513-473-10E is a horizontal-style dial test indicator designed for precision measurement in machining, inspection, and metrology applications. It reads in 0.0001 inch graduations across a 0-4-0 dial face, with a total range of 0.008 inches per revolution. The jeweled bearing mechanism supports smooth, repeatable stylus travel. The indicator features a no-clutch structure with automatic reversal, a glare-free crystal face, and an O-ring seal for dust and oil resistance. It is built for environments where contamination and vibration are common, making it well suited for production floors, tool rooms, and quality labs.

This indicator is used for surface runout checks, part alignment, and comparative gauging in both manual and CNC machine setups. The horizontal style allows the contact point to approach a workpiece from the side, which is standard for spindle alignment, chuck runout measurement, and fixture setup work. The carbide-tipped contact point and high-impact-resistant housing make it a practical choice for daily use by machinists, quality technicians, and metrologists. The 40 mm dial diameter provides a clear reading under shop lighting without glare.

Key Features

• 0.0001 inch graduation for high-resolution comparative measurement
• Jeweled bearing for smooth, long-lasting stylus movement
• No-clutch automatic reversal eliminates manual reset between readings
• O-ring seal and dust-and-oil-proof construction for shop environments
• Glare-free, scratch-resistant crystal over a white 40 mm dial face
• Carbide-tipped contact point included for wear resistance

Compatibility

Designed as an OEM-style horizontal dial test indicator in the MITUTOYO Series 513 product line. Includes one contact point, knurled clamp ring, and stem for standard indicator holder mounting.

Installation Notes

Dial test indicators are typically installed and used by machinists and quality technicians. Secure the stem in a magnetic base, indicator holder, or arm clamp before bringing the contact point into contact with the workpiece. Preload the stylus slightly before zeroing the dial to ensure consistent readings. Avoid lateral side-loading the stylus beyond the intended contact angle, as this can affect accuracy and bearing life over time.
