Shop Insize 3227-40 Three Point Internal Micrometer 30-40 mm In Iraq Best Prices
The Insize 3227-40 Three-Point Internal Micrometer is engineered for precision measurement of internal diameters ranging from 30 to 40 mm. Designed for industrial machining, inspection tasks, and quality-control environments, it delivers accurate and repeatable internal bore measurements with high stability.
The three-point contact system ensures automatic self-centering inside the bore, providing uniform contact and reducing alignment errors. With an ultra-fine 0.001 mm graduation, this micrometer is ideal for measuring machined holes, cylinders, sleeves, internal cavities, and precision-engineered components.
A ratchet-stop thimble ensures consistent measuring pressure, improving repeatability. This model includes a calibration setting ring and an extension rod for deeper bore access, making it suitable for workshop, factory, and metrology lab use.
