The Insize 3282-25 is a precision 25mm Disk Micrometer (disc anvil type) from Insize, specially designed for measuring the root tangent length of gears, thin materials like paper/foil/sheet metal, or other narrow/recessed surfaces where standard flat anvils cannot reach accurately. It features disc-shaped anvils (typically 20mm diameter, 3.3mm thickness) for excellent contact on curved or small-area surfaces
