Mitutoyo 513-415-10T Horizontal Dial Test Indicator

Product Description

The MITUTOYO 513-415-10T is a horizontal dial test indicator designed for precise surface, runout, and concentricity measurements in machine shop and inspection environments. It features a 40mm yellow dial with a 0-50-0 reading format, a measurement range of 1mm, and a graduation of 0.01mm, making it well suited for close-tolerance work. The jeweled bearing movement supports smooth, consistent needle response. A carbide-tipped contact point resists wear during repeated probing cycles. This indicator is installed and used by machinists, quality control technicians, and tool-and-die professionals.

The 513-415-10T is used in horizontal indicator applications where a low-profile sensing head is required, such as checking bore alignment, surface parallelism, and spindle runout on mills, lathes, and surface plates. The yellow dial face provides high contrast for fast visual readings under shop lighting conditions. Two contact points are included, giving the technician flexibility for different probing geometries. The no-clutch structure reduces mechanical complexity and supports long service life in production environments.

Key Features

• 1mm measurement range with 0.01mm graduation for fine-resolution readings
• Jeweled bearing movement for smooth, low-friction needle travel
• Carbide-tipped contact point for extended wear resistance
• Dust and oil proof construction with O-ring seal for shop environments
• Glare-free, scratch-resistant crystal with high-impact resistance
• No-clutch structure with automatic reversal for simplified operation
• Includes 2 contact points; 0.078 inch ball diameter

Compatibility

Designed as an OEM-style horizontal dial test indicator suitable for use with standard dovetail indicator holders and back-plunger style indicator arms commonly used in machine shop and metrology setups.

Installation Notes

Dial test indicators of this type are mounted by machinists or quality technicians using a dovetail clamp or articulating arm holder. Secure the stem or dovetail mount firmly before zeroing the indicator to prevent measurement drift. Avoid side-loading the contact spindle beyond the rated travel range, as this can damage the jeweled bearing. Follow the equipment manufacturer guidelines for any machine tool or surface plate fixture used in conjunction with this indicator.
