Mitutoyo 2414A Dial Drop Indicator 0.5 in 0.001 in Grad

Product Description

The MITUTOYO 2414A is a dial drop indicator designed for precision dimensional measurement in machining, inspection, and metrology applications. It delivers a 0.5 inch total range with 0.001 inch graduations, providing repeatable readings on a 0-100 white dial face that is 2-1/4 inches in diameter. The lug back mount allows for secure fixturing in standard indicator holders and surface-plate setups. A built-in revolution counter tracks cumulative travel across the 0.1 inch per revolution sweep, reducing the chance of misreading accumulated displacement. This instrument meets ANSI/AGD standards and carries an AGD Group 2 designation.

The 2414A is suited for machine shop, quality control, and toolroom environments where tight dimensional tolerances must be verified. Typical applications include runout inspection, part height comparison, fixture alignment, and surface flatness checks on manual or CNC setups. The 0.375 inch stem diameter fits standard AGD Group 2 dovetail holders and indicator stands. It is appropriate for use by machinists, metrology technicians, and quality control inspectors working in both job-shop and production environments.

Key Features

• 0.5 inch measuring range with 0.001 inch graduation for fine-tolerance inspection
• 0-100 white dial face with 2-1/4 inch diameter for clear, low-fatigue reading
• Revolution counter tracks cumulative travel beyond a single sweep
• Lug back mount for compatibility with standard AGD indicator holders and arms
• 0.375 inch stem diameter fits AGD Group 2 mounting accessories
• Meets ANSI/AGD standards; AGD Group 2 classified

Compatibility

Designed as an AGD Group 2 drop indicator compatible with standard indicator holders, magnetic bases, and surface-plate stands that accept a 0.375 inch stem diameter.

Installation Notes

Mount and secure the indicator in a calibrated holder or magnetic base before taking measurements; a loose mount will introduce error. Verify zero before each measurement session by lifting the spindle and confirming return to the original reading. Measuring force is 1.80 N; do not exceed the rated range, as overtravel can damage the gear train. This instrument should be handled and stored by qualified inspection or machining personnel following shop metrology procedures.
