Mitutoyo 1410AB Dial Drop Indicator 0.001 Inch Graduation

Product Description

The MITUTOYO 1410AB is a dial drop indicator designed for precision measurement applications where a standard dial test indicator cannot reach. This instrument features a 1/4 inch total measurement range with 0.001 inch graduation, allowing for fine, accurate readings across a 0-100 dial scale. The 40mm dial face provides clear readability, and a built-in revolution counter tracks full rotations so technicians can monitor cumulative travel without losing position. It is used by machinists, quality control inspectors, and precision measurement professionals who need reliable, repeatable drop-style indicator performance on the shop floor or inspection bench.

The 1410AB is suited for use in setups where the measuring spindle must drop vertically to contact the workpiece — common in surface plate inspection, fixture alignment, and machine tool calibration. Its 0.1 inch range per revolution makes it practical for both coarse setup and fine verification passes. The ANSI/AGD standard construction ensures compatibility with standard indicator holders, magnetic bases, and inspection fixtures used throughout manufacturing and metrology environments.

Key Features

• 1/4 inch total measurement range with 0.001 inch graduation for high-resolution readings
• 0-100 dial reading scale with 40mm dial face for clear, at-a-glance measurement
• Built-in revolution counter tracks cumulative spindle travel across multiple rotations
• 0.1 inch range per revolution supports both coarse positioning and fine measurement
• ANSI/AGD standard construction for compatibility with common indicator mounting hardware
• No. 4-48 thread size on contact point for standard tip interchangeability

Compatibility

Conforms to ANSI/AGD standards and fits AGD Group 0 indicator holders, magnetic bases, and inspection fixtures that accept standard drop-style dial indicators.

Installation Notes

Installation is performed by metrology technicians or machinists using a compatible indicator holder, magnetic base, or fixture arm. Secure the indicator stem firmly before zeroing the dial to avoid measurement drift. Avoid side-loading the spindle during mounting, as this can affect accuracy and damage the internal mechanism. Handle with care and store in a protective case when not in use to preserve calibration.
