Precision measurement range and accuracy: 010 mm measuring capacity with 0.01 mm accuracy, suitable for precise readings in machining, assembly, and inspection tasks. Strong magnetic base: 60 kg (130 lb) holding force; securely attaches to flat or cylindrical surfaces via a Vgroove, providing stable support during inspection dial test work. Fine adjustment mechanism: integrated fineadjustment knob allows quick, accurate positioning of the gauge point, reducing setup time and improving measurement consistency for delicate engineering work. Versatile setup options: the package includes a holder, a Dial Indicator, or both; flexible for varied workshop setups and compatibility with different measuring tools in your toolkit. Use scenarios In milling or turning operations, mount the Dial Indicator on the magnetic base to check workpiece runout and verify position tolerances quickly and repeatably. When fixtureing cylindrical parts, place the Vgroove on a flat or curved surface to secure the indicator and measure diameters, heights, or steps with stable contact. During delicate assembly or inspection workflows, use the fineadjustment knob to position the gauge point precisely before taking measurements, saving setup time and reducing the risk of overtravel or damage.
