Interchangeable Outside Micrometers The Interchangeable Outside Micrometer is a versatile precision measuring instrument designed for accurate external dimension measurement across a wide range of sizes using interchangeable anvils. By replacing anvils instead of using multiple micrometers, users can achieve extensive measuring ranges with fewer instruments, making it a cost-effective solution for industrial measurement applications. Manufactured with carbide-tipped measuring faces, a satin chrome scale, insulated frame grips, and a ratchet stop mechanism, these micrometers provide excellent accuracy, durability, and measurement repeatability. Each set is supplied with setting standards for precise calibration across its measuring range. Ideal for manufacturing industries, machine shops, tool rooms, heavy engineering, automotive, aerospace, and quality control departments.
