This four-piece micrometer set enables outside diameter measurements across a 0 to 4" (0 to 10.2 cm) range using 0.0001" (0 cm) graduations. Each tool utilizes carbide measuring faces for wear resistance and friction thimbles to maintain consistent spindle pressure during inspection. The kit includes 1, 2, and 3" (25, 50 and 76 mm) standards for calibration, all organized within a plastic storage case.
