Three-Point Inside Micrometers

The three-point inside micrometer is a precision measuring tool designed for accurately checking hole diameters at every stage of production, from machining to final inspection and quality control. This specialized internal micrometer ensures highly reliable and repeatable measurements, making it essential in industrial applications where precision is critical.

Its design features a cylindrical body with an actuating rod that controls three contact points, positioned 120° apart. This configuration ensures perfect centering within the hole and exceptional measurement accuracy. A built-in friction mechanism maintains consistent measuring pressure, ensuring precise and repeatable results even during extended use.

With its advanced technology, the three-point micrometer is a key instrument for quality control and dimensional verification in high-precision industries. Available in both analog and digital versions, it is also offered in a pistol-grip design, enabling fast and accurate serial measurements.
