Mitutoyo 101191 Conical Contact Point Agd Dial Indicator

Product Description

The MITUTOYO 101191 is a conical contact point designed for use with AGD-style dial indicators. Machined with a 90-degree conical tip from solid carbide, this contact point delivers consistent, repeatable contact geometry in precision measurement applications. The contact point features a 4-48 threaded stem for secure attachment to compatible indicator spindles. The tip diameter measures 0.2 inches and the contact point length is 0.25 inches. This part is installed by metrology technicians, machinists, and quality control professionals working with dial-type gages in shop or lab environments.

This contact point is suited for use with AGD Group 1, 2, 3, and 4 dial indicators. It is commonly used in dimensional inspection setups where a conical tip geometry is required to access features such as small holes, grooves, or angled surfaces. The solid carbide construction provides extended service life in repetitive measurement cycles on metal workpieces.

Key Features

• 90-degree conical tip geometry for access to angled features and small-diameter bores
• Solid carbide point material for wear resistance in high-cycle inspection use
• 4-48 threaded stem for direct attachment to AGD-standard indicator spindles
• Contact point length of 0.25 inches with a tip diameter of 0.2 inches
• Compatible with AGD Group 1, 2, 3, and 4 dial gages

Compatibility

Designed for use with AGD 1, 2, 3, and 4 dial indicators equipped with a 4-48 threaded spindle.

Installation Notes

Installation is performed by hand-threading the 4-48 stem into the indicator spindle. Do not use pliers or wrenches directly on the contact point body, as this may damage the carbide tip or the spindle threads. Verify that the indicator spindle threads are clean and free of debris before installation. Handle carbide-tipped contact points carefully to avoid chipping the tip on hard surfaces.
