Mitutoyo 513-401-10H Dial Test Indicator 0.14mm Horizontal

Product Description

The MITUTOYO 513-401-10H is a horizontal-style dial test indicator designed for precision dimensional measurement in machine shop, toolroom, and metrology applications. It features a 0.14 mm total measurement range with a 0-70-0 dial reading and 0.001 mm graduation, delivering 10 micrometer accuracy. The 40 mm yellow dial is glare-free and scratch-resistant, making it readable under shop lighting. A jeweled bearing supports smooth stylus travel and long service life. The no-clutch structure and automatic reversal mechanism allow the contact tip to follow surfaces in both directions without manual reset. Licensed HVAC techs, machinists, quality inspectors, and tool-and-die professionals are the primary users.

This indicator is suited for surface runout checks, alignment tasks, and part inspection on manual mills, lathes, surface plates, and CMM fixtures. It is a horizontal-style unit, meaning the contact point travels parallel to the indicator body axis, which is the preferred configuration for many spindle-mounted and magnetic-base setups. The carbide-tipped contact point resists wear during repeated contact cycles. The dust- and oil-proof housing with O-ring seals makes it appropriate for wet-machining and grinding environments. Package includes a contact point, dial indicator body, knurled clamp ring, and stem.

Key Features

• 10 micrometer accuracy across the full range
• Jeweled bearing construction for reduced friction and extended service life
• Automatic reversal and no-clutch structure for bidirectional stylus travel
• Carbide-tipped contact point for wear resistance in production environments
• Dust- and oil-proof housing with O-ring seal suitable for machine tool use
• 40 mm yellow dial with glare-free, scratch-resistant crystal for clear readability

Compatibility

Part of the MITUTOYO 513 Series of dial test indicators. Designed for use with standard stem-mount and dovetail-mount indicator holders, magnetic bases, and universal clamp arms commonly found in toolroom and inspection setups.

Installation Notes

Dial test indicators are installed by machinists, metrologists, and quality technicians using magnetic base stands, universal arm holders, or machine spindle adapters. Secure the stem or dovetail mount firmly before zeroing the dial to prevent drift during measurement. Avoid side-loading the contact point beyond the rated angular travel range, as this can damage the jeweled bearing. Clean the contact point and seating surfaces before mounting to ensure accurate readings.
