Starrett 124DZ 2-32in 0.001in Inside Micrometer Set

The Starrett 124DZ (EDP 50554) is a mechanical inside micrometer set covering a 2–32 inch measurement range with 0.001 inch graduation, achieved through a micrometer head and 10 interchangeable extension rods stored in a fitted hardwood case. The micrometer head provides a 1-inch measuring range per assembly, and each extension rod adds 1 inch of reach (except the 2–3 inch rod); rods must be aligned to the reading line on the head per the included instruction card before use. All contact surfaces and measuring rods carry a satin chrome finish for corrosion resistance and reduced glare during reading. This set is suited for measuring large bores, cylinders, and internal diameters in engine rebuilding, heavy-equipment maintenance, and precision machining where long-reach internal measurement is required. This item is new — other, meaning it is in original factory packaging and has not been used, but may show minor cosmetic wear to the outer box.
