Shop Insize 3227-88 Three Point Internal Micrometer 75-88 mm In Iraq Best Prices
The Insize 3227-88 Three-Point Internal Micrometer is designed for precise measurement of internal diameters within the 75–88 mm range. Built for industrial machining, inspection labs, and precision-quality environments, it ensures highly stable, accurate, and repeatable measurements for medium-to-large bores.
The three-point contact system provides automatic self-centering inside the bore, ensuring even internal contact and minimizing alignment errors for superior accuracy. With an ultra-fine 0.001 mm graduation and ±5 µm accuracy, this tool is ideal for measuring internal cavities, machined holes, cylinders, housings, and industrial components requiring tight tolerances.
A ratchet-stop thimble ensures uniform measuring pressure. The micrometer comes with a calibration setting ring and extension rod, making it suitable for deeper internal measurement tasks across professional workshops and production facilities.
