Baker 7-8 inch Blade Type External Micrometer, INC8 (B-BA)

he Baker 7-8 inch Blade Type External Micrometer, often denoted as INC8 (B-BA), is a precision measuring instrument used for accurately measuring the outside diameter of cylindrical objects within the range of 7 to 8 inches (or approximately 177.8 to 203.2 millimeters). This micrometer is specifically designed with blade-type measuring faces for applications where objects have flat surfaces, such as shafts or pipes. Here are the key features and components specific to the Baker 7-8 inch Blade Type External Micrometer, INC8 (B-BA): Measuring Range: Capable of measuring objects with diameters ranging from 7 to 8 inches. Blade Type Measuring Faces (B-BA): Unlike standard micrometers with flat measuring faces, this micrometer features blade-type measuring faces labeled as B and BA. These blades allow for precise contact with the surface of the cylindrical object being measured, particularly useful for objects with flat surfaces. Anvil and Spindle: The micrometer includes a stationary anvil and a movable spindle. Both the anvil and spindle have blade-type measuring faces (B and BA) for accurate measurements. Frame, Thimble, and Sleeve: These components provide structural support and mechanisms for adjusting and reading measurements, similar to standard micrometers. Sleeve Graduations: The sleeve of the micrometer is graduated with markings representing units of measurement (e.g., inches or millimeters), allowing users to read measurements accurately.
