A precision measuring tool reading micro-displacements via pointer swing, with 0.01mm precision. Commonly used for machine tool accuracy calibration and workpiece geometric tolerance inspection (e.g., roundness, perpendicularity), crucial for dimensional and geometric accuracy control in machining.
Inch dial indicators adjust to imperial measures, with an incorporated metric conversion and 0-1” face dial. A 0.001” resolution eases measurements while the added reversable pointer along with adjustable plunger up to 2” further allows for internal and external measurements. Predominantly used in North American manufacturing, these indicators surpass ASME B89.1.2 standards making them popular in automotive engine rebuilding and sheet metal fabrication.
Frequently Asked Questions
