Mitutoyo 1410AB-10 Dial Drop Indicator 0.25 in Range

Product Description

The MITUTOYO 1410AB-10 is a dial drop indicator designed for precise vertical displacement measurements in shop, tool room, and inspection applications. It features a 0.001 inch graduation over a 0 to 0.25 inch total range, with a 0-100 dial reading and 0.1 inch travel per revolution. The flat back design allows the indicator to sit flush against a magnetic base or fixture without additional standoffs. Accuracy is rated at 0.001 inch, making it suitable for surface plate inspection, runout checks, and fixture setups. The white dial face provides high contrast for quick, reliable readings. Licensed metrologists, machinists, and quality control technicians are the primary users.

This drop indicator is used in dimensional inspection and machine setup tasks across manufacturing, metalworking, and tool room environments. It is well suited for measuring vertical drop on horizontal surfaces, checking flatness, and verifying part alignment. The 3/8 inch stem diameter fits standard indicator holders and magnetic base clamps commonly found in machine shops and inspection departments. The unit reads in inches and is appropriate for applications where imperial measurement is required.

Key Features

• 0.001 inch graduation for fine-resolution vertical displacement measurement
• 0 to 0.25 inch total measurement range with 0-100 dial reading
• 0.1 inch travel per revolution for straightforward reading without revolution counting errors
• Flat back design for flush mounting against bases and fixtures
• White dial face for high-contrast, easy-to-read display
• 3/8 inch stem diameter fits standard indicator holders and magnetic bases
• 1.40 N measuring force minimizes deflection of delicate workpieces

Compatibility

Designed as an OEM-style drop indicator for use with standard 3/8 inch diameter indicator holders, magnetic bases, and surface plate fixtures common in machine shop and inspection environments.

Installation Notes

Mounting and removal should be performed by a qualified machinist or metrologist familiar with indicator setups. Secure the 3/8 inch stem in the holder clamp without overtightening, as excess clamping force can affect stem travel and measurement accuracy. Verify the contact point is perpendicular to the measured surface before zeroing the dial. Keep the spindle and contact point clean and free of chips or coolant to maintain consistent measuring force and accuracy.
