Mitutoyo 101385 Conical Contact Point 90 Degree Drop Indicator

Product Description

The MITUTOYO 101385 is a conical contact point designed for use with drop indicators and dial indicators in precision measurement applications. Featuring a 90-degree conical tip machined from solid carbide, this contact point delivers consistent, repeatable readings in tight-tolerance inspection work. The M2.5 x 0.45 threaded shank provides a secure attachment to compatible indicator stems. With a contact point length of 5 mm and a tip diameter of 5 mm, the 101385 suits a range of surface and bore measurement setups. Metrologists, quality control technicians, and toolroom machinists install and replace contact points as part of routine indicator maintenance.

This contact point is suited for dimensional inspection tasks where a conical tip is required to access recessed features, chamfers, or angled surfaces. It is appropriate for use in both shop-floor and laboratory measurement environments. The solid carbide construction provides wear resistance in high-cycle inspection routines, making it a practical choice for production quality control as well as precision toolroom work. The 5 mm diameter measurement face corresponds to 0.2000 decimal inches, relevant when cross-referencing inch-based inspection records.

Compatibility

The MITUTOYO 101385 is designed for use with AGD Group 1, 2, 3, and 4 drop and dial indicators accepting an M2.5 x 0.45 threaded contact point.

Installation Notes

Contact point replacement is performed by metrologists and toolroom technicians using a contact point wrench or spanner appropriate for the indicator model. The indicator stem should be secured before threading in the contact point to avoid applying torque to the indicator mechanism. Ensure the threads are clean and free of debris before installation. Follow the indicator manufacturer's guidance on contact point seating and any required calibration verification after replacement.
