Mitutoyo 513-304-10E Horizontal Dial Test Indicator

Product Description

The MITUTOYO 513-304-10E is a horizontal-style dial test indicator designed for precision measurement work in machine shops, toolrooms, and manufacturing environments. It features a plain bearing mechanism and a yellow dial face for clear reading in various lighting conditions. The clamp mount style allows for versatile setup on magnetic bases, surface plates, and machine fixtures. This indicator is used by machinists, metrology technicians, and tool-and-die professionals who require accurate surface runout, alignment, and deflection measurements during setup and inspection operations.

The 513-304-10E suits a wide range of horizontal measurement tasks in both production and inspection settings. Its clamp mount design integrates readily with standard indicator holders and articulating arms commonly found on milling machines, lathes, and surface plates. The instrument ships with one contact point included. It is not factory-calibrated or supplied with a traceability certification, making it suited for general-purpose measurement applications where in-house calibration procedures are in place.

Key Features

• Horizontal indicator style for low-profile, side-approach measurement setups
• Plain bearing mechanism provides smooth, consistent needle response
• Yellow dial face improves readability under shop lighting conditions
• Clamp mount type supports use with standard indicator holders and magnetic bases
• Includes one contact point for immediate use out of the box

Compatibility

Designed as a general-purpose horizontal dial test indicator compatible with standard clamp-style indicator holders and articulating arm fixtures commonly used in machine shop and metrology applications.

Installation Notes

Dial test indicators are typically installed and adjusted by machinists or metrology technicians. Secure the clamp mount firmly to the holder or arm before zeroing the dial to prevent measurement drift. Handle the contact point and spindle with care to avoid shock loading, which can damage the internal bearing and gear train. When not in use, store the indicator in its case away from coolants, chips, and vibration sources.
