Mitutoyo 513-403-10E Dial Test Indicator 0.008 in

Product Description

The MITUTOYO 513-403-10E is a horizontal-style dial test indicator designed for precision measurement in machining, inspection, and metrology applications. It delivers a maximum measurement range of 0.008 inches per revolution with a dial graduation and accuracy of 0.0001 inches, making it suitable for high-precision runout, flatness, and surface alignment checks. The 40 mm white dial features a glare-free crystal and a scratch-resistant face for clear, consistent readability. Jeweled bearings reduce friction and extend service life under repeated use. Licensed machinists, tool-and-die technicians, and quality-control inspectors are the primary users of this instrument.

This indicator is used in machine shops, manufacturing facilities, and quality inspection environments where tight tolerances must be verified. The horizontal style allows contact-point access in confined or low-clearance setups typical of surface plates, mill tables, and lathe applications. The 0-4-0 balanced dial reading supports bidirectional deviation measurement without repositioning. The included carbide-tipped contact point measures 15.00 mm (0.5906 inches) in length with a 0.0790-inch ball diameter. The unit ships with a contact point, the dial indicator body, a knurled clamp ring, and a stem for immediate deployment.

Key Features

• 0.0001-inch graduation and accuracy for high-precision deviation measurement
• Jeweled bearing construction for smooth, repeatable stylus movement
• Dust- and oil-proof body with O-ring seal for shop-floor durability
• Glare-free, scratch-resistant crystal over a 40 mm white dial
• Automatic reversal and no-clutch structure for consistent bidirectional use
• Carbide-tipped contact point resists wear on hardened surfaces

Compatibility

Part of the MITUTOYO Series 513 dial test indicator line. The included stem and knurled clamp ring are compatible with standard indicator holders and magnetic base assemblies that accept the Series 513 mounting configuration.

Installation Notes

Dial test indicators are installed and serviced by machinists, metrologists, and inspection technicians. Before mounting, verify the indicator stem is fully seated and the clamp ring is secure to prevent measurement drift. Avoid applying side loads or impact to the contact point, as this can damage the jeweled bearing assembly. Handle the crystal and dial face with care to preserve scratch resistance and readability.
