Mitutoyo 101190 Conical Contact Point Agd Dial Indicator

Product Description

The MITUTOYO 101190 is a conical contact point designed for use with dial indicators in precision measurement applications. Featuring a 60-degree conical tip geometry machined from solid carbide, this contact point provides consistent, repeatable contact in tight-tolerance inspection work. The tip measures 0.2 inches in diameter with a contact point length of 0.5 inches and uses a 4-48 threaded shank for secure mounting. It is suited for metrology professionals, quality control technicians, and machine shop inspectors who require reliable stylus performance with AGD-style dial gages.

This contact point is intended for use with AGD Group 1, 2, 3, and 4 dial indicators, making it a versatile replacement or spare for a range of standard dial gage setups. Typical applications include surface inspection, bore measurement setups, and fixture-based gauging in both production and toolroom environments. The solid carbide construction resists wear during high-cycle inspection routines, maintaining measurement accuracy over extended service life.

Key Features

• 60-degree conical point geometry for precise contact in restricted-access measurement locations
• Solid carbide construction for wear resistance in repetitive inspection cycles
• 0.2 inch tip diameter provides a defined, consistent contact area
• 0.5 inch contact point length suits standard AGD dial indicator reach requirements
• 4-48 threaded shank for direct installation into AGD-compatible dial indicators
• Compatible with AGD Group 1, 2, 3, and 4 dial gages

Compatibility

Designed for use with AGD Group 1, 2, 3, and 4 dial indicators. Dial gages are suitable for mounting with this contact point installed.

Installation Notes

Installation is performed by quality control technicians or machinists familiar with dial indicator servicing. Before replacing the contact point, ensure the dial indicator is removed from any active fixture or measurement setup and that no clamping force is applied to the gage spindle. Use the appropriate spanner or flat-end wrench sized for the 4-48 thread to avoid damaging the stylus or spindle tip. Do not overtighten the contact point, as this can affect spindle travel and measurement accuracy.
