Mitutoyo 513-414-10T Horizontal Dial Test Indicator

Product Description

The MITUTOYO 513-414-10T is a horizontal dial test indicator designed for high-precision measurement in machining, inspection, and alignment applications. It features a 40mm yellow dial with a 0-25-0 readout format and a graduation of 0.01mm, giving technicians fine resolution over a 1mm total range. The jeweled bearing mechanism reduces friction and wear for consistent, repeatable readings. An O-ring seal and dust- and oil-proof construction protect the internal mechanism in shop environments. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of this instrument.

This indicator suits horizontal contact measurement setups on surface plates, milling machines, lathes, and CMM fixtures. The 0-25-0 bidirectional dial with automatic reversal allows fast back-and-forth traverse checks without resetting. Two contact points are included, and the carbide-tipped contact provides wear resistance during repeated probing cycles. The glare-free crystal and yellow dial background improve readability under shop lighting conditions. It is suited for both production floor use and tool-room inspection work.

Key Features

• Jeweled bearing construction for low friction and long service life
• O-ring seal with dust- and oil-proof housing for shop-floor durability
• Automatic reversal mechanism eliminates the need for a clutch structure
• Carbide-tipped contact point resists wear during high-cycle use
• Glare-free, scratch-resistant crystal over a high-visibility yellow dial
• Includes 2 contact points for versatile probing setups

Compatibility

Designed as an OEM-style horizontal dial test indicator compatible with standard indicator holders, magnetic bases, and dovetail-mount arms used in general metrology and machine tool setup.

Installation Notes

Installation is performed by metrology technicians or machinists using a compatible dovetail clamp or stem-mount holder. Ensure the contact point is aligned perpendicular to the measurement surface to avoid cosine error. Do not overtighten the clamping screw on the indicator stem, as excess clamping force can distort the housing and affect calibration. Handle the instrument carefully to avoid shock loads that can damage the jeweled bearing assembly.
