The 0-25 mm Metric Outside Micrometer from the 3203 Series by Insize is a precision hand tool built for machinists, inspectors, and workshop professionals who need reliable external measurements with clean, repeatable results.
- Graduation: 0.01 mm increments for fine, repeatable readings
- Measuring faces: Carbide measuring faces extend tool life and resist wear in busy shop environments
- Measurement range: Designed to handle workpieces up to 300 mm, offering versatility for a wide range of parts
- Setting standards: Supplied with setting standards for quick calibration (except the 0–25 mm size)
- Construction: Robust outside micrometer with a durable frame and precise thimble for everyday use
This micrometer delivers stable, accurate measurements essential for quality control and production workflows. The 0.01 mm graduation supports tight tolerances on components, while carbide faces reduce wear over time, maintaining measurement integrity across many cycles. The broad range up to 300 mm makes it a practical choice for various external dimension checks, from small components to larger assemblies. With included setting standards (where applicable), setup is faster and more consistent, helping you maintain high inspection standards without unnecessary downtime.
