Mitutoyo 101118 Drop Indicator Shell Contact Point

Product Description

The MITUTOYO 101118 is a shell-style contact point designed for drop indicators and dial gages. It threads directly onto the indicator spindle using an M2.5 x 0.45 thread and provides a 5 mm diameter contact surface with a 10 mm contact point length. The tip is manufactured from solid carbide, which resists wear during repeated measurement cycles. This contact point is a precision measurement accessory used by machinists, quality control technicians, and metrology professionals who require consistent, repeatable gage readings on flat or contoured workpiece surfaces.

This contact point is suited for use in machine shops, inspection rooms, and production floor quality control stations where AGD-style drop indicators are standard equipment. It is appropriate for both surface plate work and in-fixture measurement setups. Compatible with AGD Groups 1, 2, 3, and 4 drop indicators, it covers a broad range of standard dial gage configurations commonly found in metalworking and manufacturing environments.

Key Features

• Shell contact point style for secure spindle engagement on AGD drop indicators
• Solid carbide tip construction for extended wear resistance under repetitive contact
• 10 mm contact point length for standard reach in typical measurement applications
• 5 mm diameter contact face suitable for flat and moderately curved surfaces
• M2.5 x 0.45 thread matches standard AGD indicator spindle threads

Compatibility

Designed for use with AGD Group 1, 2, 3, and 4 drop indicators and dial gages suitable for mounting.

Installation Notes

Installation is performed by threading the contact point onto the indicator spindle by hand, then snugging with an appropriate wrench to avoid cross-threading the fine M2.5 x 0.45 thread. Do not overtighten, as this can damage the spindle thread or alter gage zero. Zero the indicator after replacing the contact point to account for any variation in contact point length. Contact point replacement is a standard metrology maintenance task performed by calibration technicians or qualified inspection personnel.
