Mitutoyo 133195 Ball Contact Point 0.65 Inch Carbide 513 Series

Product Description

The MITUTOYO 133195 is a ball-style contact point designed for use with dial test indicators in precision measurement applications. Machined from carbide, this contact point offers the wear resistance required for repeated use on hardened surfaces and high-cycle inspection routines. The ball tip measures 2.00 millimeters in diameter, providing consistent and repeatable point contact for surface runout, bore alignment, and feature-location checks. This type of accessory is installed by metrology technicians, quality control inspectors, and precision machinists who rely on accurate indicator readings in shop floor or CMM-adjacent workflows.

This contact point is specifically designed for use with Mitutoyo 513 Series dial test indicators. It is suited for dimensional inspection tasks in both production and toolroom environments, including checking part runout, verifying flatness, and confirming alignment during setup. The ball contact geometry is preferred when inspecting curved or contoured surfaces where a sharp stylus would produce inconsistent seating. The 0.65 inch contact point length provides adequate reach for standard indicator setups without introducing excessive flex or measurement error.

Key Features

• Carbide construction for extended wear life on hardened and abrasive surfaces
• Ball-style tip geometry for consistent contact on curved, contoured, or irregular workpiece surfaces
• 2.00 millimeter tip diameter for precise, repeatable point contact
• 0.65 inch contact point length compatible with standard 513 Series indicator arm geometry
• Drop-in replacement format minimizes downtime during stylus changeover

Compatibility

Designed for use with Mitutoyo 513 Series Dial Test Indicators.

Installation Notes

Contact point replacement is performed by quality technicians or machinists and requires no special tooling beyond a small wrench or pin spanner appropriate for the indicator thread. Power-down or machine shutdown procedures apply when the indicator is mounted on active CNC or automated inspection equipment. Avoid overtightening the contact point, as excessive torque can damage the indicator spindle thread. Handle carbide tips carefully to prevent chipping from impact with hard surfaces.
