Mitutoyo 101120 Conical Contact Point Agd Dial Indicator

Product Description

The MITUTOYO 101120 is a conical contact point designed for use with AGD-style dial indicators. It features a 60-degree conical tip geometry machined from solid carbide for long service life and consistent measurement performance. The contact point has a 5 mm body diameter and a 10 mm contact point length, with an M2.5 x 0.45 threaded shank for secure attachment to compatible indicator spindles. It is used by metrology technicians, machinists, and quality control professionals who require precise surface contact geometry for inspection work on contoured or recessed features.

This contact point is suited for bench inspection and in-process gauging applications where a standard ball-tip point would not provide adequate contact on angled or conical surfaces. The 60-degree point geometry allows access to features such as countersinks, chamfers, and narrow grooves. It is compatible with AGD Groups 1, 2, 3, and 4 dial indicators, making it broadly applicable across standard dial gauge sets used in manufacturing and machine shop environments.

Key Features

• 60-degree conical tip for access to countersinks, chamfers, and recessed geometry
• Solid carbide construction for wear resistance and dimensional stability
• 10 mm contact point length provides reach into confined measurement areas
• 5 mm body diameter for rigid support during indicator contact
• M2.5 x 0.45 thread fits standard AGD indicator spindle threads
• Compatible with AGD Groups 1, 2, 3, and 4 dial indicators

Compatibility

Designed for use with AGD Group 1, 2, 3, and 4 dial indicators with M2.5 x 0.45 threaded spindles.

Installation Notes

Installation is performed by metrology technicians or machinists. Power down or de-energize any automated gauging fixture before changing contact points. Thread the contact point onto the indicator spindle by hand and snug securely without over-torquing, as carbide tips can be brittle under side loading. Verify that the replacement contact point does not affect the indicator's calibrated range before returning the instrument to service.
