Mitutoyo 513-406-10T Horizontal Dial Test Indicator

Product Description

The MITUTOYO 513-406-10T is a horizontal dial test indicator designed for precision measurement in machining, inspection, and quality control applications. It features a 40mm dual-color white and yellow dial with a graduation of 0.0005 inches and a measurement range of 0 to 0.03 inches. The indicator uses a jeweled bearing for smooth, consistent needle movement and accuracy to 0.0005 inches. The no-clutch structure and automatic reversal mechanism reduce wear and improve repeatability over extended use. Qualified machinists, metrologists, and precision inspection technicians are the primary users of this instrument.

This horizontal-style dial test indicator is suited for surface plate work, lathe and mill setup, fixture alignment, and incoming inspection tasks in both job shop and production environments. The horizontal contact arm geometry makes it well-suited for accessing tight spaces and measuring inside bores, slots, or around obstructions where a vertical indicator would not fit. Two contact points are included to accommodate different measurement setups. The glare-free crystal and scratch-resistant face support consistent readability under shop lighting conditions.

Key Features

• Jeweled bearing construction for smooth needle travel and long service life
• Automatic reversal mechanism with no-clutch structure reduces internal wear
• Dust and oil proof with O-ring seal for use in typical shop environments
• 40mm dual-color dial (white and yellow) with glare-free, scratch-resistant crystal
• Includes 2 contact points for setup flexibility
• High-impact resistance for durability in production and field inspection use

Compatibility

Designed as an OEM-style precision instrument compatible with standard indicator holders, magnetic base arms, and test indicator mounting systems that accept common shank sizes used in dial test indicator setups.

Installation Notes

Installation is performed by qualified machinists or metrology technicians using a magnetic base, indicator holder, or dedicated fixture arm. Ensure the contact point is positioned to contact the workpiece at the correct angle of deflection to maintain measurement accuracy. Do not overtighten the mounting clamp on the indicator body, as excessive clamping force can affect readings. Follow the machine or fixture manufacturer guidelines for securing and zeroing the indicator before taking measurements.
