The 9-10 inch Imperial Outside Micrometer from Insize, part of the 3203 Series, is a trusted tool for precise outside-diameter measurements. It’s ideal for engineers, machinists, and hobbyists who need quick, repeatable readings on parts and tools. With a 0.0001 inch graduation and carbide measuring faces, this micrometer delivers accurate results while standing up to the rigors of daily shop use. This model is known as one of Insize’s best-selling outside micrometers, balancing precision, durability, and real-world value.

  • 0.0001 in graduation: Delivers high-accuracy readings in a single, clear step, helping you verify tight tolerances quickly and with confidence.
  • Carbide measuring faces: Extend tool life and resist wear from frequent contact with parts, maintaining accuracy over many cycles of use.

This outside micrometer is designed to streamline measurement workflows, reduce rework, and deliver consistent results across multiple operators and shifts. The combination of a precise 0.0001" graduation, durable carbide faces, and convenient setting standards helps you measure with reliability, speed up setup and inspection tasks, and maintain quality across your production or hobby projects.
