Product Description These gauges are suitable for measuring hole diameters and detecting ovality and tapers in bores. Key Features - Measure bores accurately to maintain tight tolerances - Detect and correct ovality and taper during the machining process - Assess the internal dimensions of engine components - Detect wear and ensure parts are within serviceable limits - Fitted with a spring preloaded centralising mechanism to ensure the true diameter of holes being measured - A wide range of anvils with a large radius allow close tolerance repeatability - Large LCD display with digital read-out and auto-power off - Dual scale: convertible between metric and imperial units (mm/inch) - Data output - Zero reset - Mode selection: Data hold, Fast searching for max. and min. values (vary by model) - Shock and dust proof - Battery included and the instrument is ready to use Specification -Digital Bore Gauges -Range: 50-160mm/Resolution: 0.001mm/0.0005"/Stem Length: 212mm
