Mitutoyo 136077 Ball Contact Point 0.1181 in Steel

Product Description

The MITUTOYO 136077 is a ball-style contact point designed for use with dial test indicators in precision measurement applications. The contact tip measures 0.1181 inches (3.00 mm) in diameter and is machined from steel for consistent surface contact and durability under repeated use. The contact point length is 0.59 inches. Metrology technicians, tool room machinists, and quality control inspectors use this type of accessory to extend or replace worn contact points on dial test indicators, maintaining measurement accuracy on bores, grooves, and contoured surfaces.

This contact point is suited for shop floor and quality lab environments where precision measurement of dimensional variation is required. It attaches to the indicator spindle to provide positive contact on workpiece surfaces during runout checks, surface comparison measurements, and alignment verification. Its ball-style geometry is particularly effective when measuring curved or recessed features that flat or pointed tips cannot contact reliably.

Key Features

• Ball tip diameter of 0.1181 inches (3.00 mm) for contact on curved and recessed surfaces
• Contact point length of 0.59 inches for standard indicator reach
• Steel construction for wear resistance and dimensional stability
• Designed as a direct replacement or spare for Mitutoyo 513 Series dial test indicators
• Single-piece package quantity suitable for individual replacement needs

Compatibility

Designed for use with Mitutoyo 513 Series Dial Test Indicators.

Installation Notes

Contact point replacement is typically performed by metrology technicians or machinists. Before swapping the contact point, remove the indicator from the measuring fixture or magnetic base to avoid dropping or damaging the spindle. Use the appropriate wrench or driver as specified by the indicator manufacturer to avoid cross-threading the contact point fitting. Handle the ball tip carefully to prevent nicking the contact surface, which would compromise measurement accuracy.
