This tool is commonly used in engineering, machining, and quality control to ensure that internal dimensions meet specified tolerances. Unlike traditional inside micrometers, the three-point contact system allows for more stable and reliable measurements, particularly in larger bores.

6-12mm graduation: 0.001mm Steel measuring faces 12-300mm graduation: 0.005mm Carbide measuring faces Ratchet stop Extension rod are included Setting rings are included (Range < 100mm) How it works: Three-point contact: The micrometer has three measuring points that evenly distribute pressure on the inner surface of the hole, ensuring accurate and repeatable measurements.

Digital display: The measured diameter is displayed digitally, eliminating the need for manual reading and reducing the possibility of errors. Extension rods: These can be used to measure deeper holes. Applications Machining and Metalworking: Used to measure the internal diameters of bores and holes in metal components, ensuring that they meet the required specifications.

Quality Control: Essential in inspection processes to verify the accuracy of internal dimensions in manufactured parts. Engineering: Applied in various engineering tasks where precise internal measurements are critical, such as in the design and fabrication of mechanical parts. Automotive and Aerospace Industries: Used for measuring the internal diameters of engine cylinders, bearing races, and other critical components that require precise tolerances.

Advantages of Three-Point Micrometers: Improved accuracy: Ensures precise centering and measurement compared to two-point micrometers. Reduced measurement error: Minimizes the impact of bore irregularities. Suitable for various shapes: Can be used for both cylindrical and irregular bores.
