Inhouse product
The INSIZE 3222-600 Tubular Inside Micrometer (50–600mm) is a professional-grade internal measuring instrument engineered for accurate measurement of large internal diameters and deep bores. Designed for industrial metrology, CNC machining, heavy engineering, and quality control applications, this tubular inside micrometer delivers consistent accuracy, rigidity, and repeatability across extended measuring ranges.
Built to INSIZE’s globally trusted precision standards, the 3222-600 model is ideal for measuring engine cylinders, hydraulic pipes, bearing housings, sleeves, and deep internal bores where standard calipers or bore gauges fall short. Its modular tubular design allows stable measurement over long depths while maintaining precise alignment inside the bore.
This micrometer is widely used in machine shops, tool rooms, manufacturing plants, automotive workshops, power plants, and industrial inspection labs where micron-level accuracy is non-negotiable.
Covers small to large internal diameters using extension rods, making it a versatile solution for multiple bore sizes.
