A bore gage is a precision tool used to measure the internal diameter of a hole.
It is commonly used in fields like manufacturing, automotive maintenance, and construction. The principle of operation involves using the bore gage to measure a hole's diameter and comparing it against standard sizes, often using ring gages or pipe gages for verification.
Bore gages are essential for inspecting the machining accuracy of mechanical parts and ensuring the proper fit of components. These tools are designed for precise measurement of hole diameters, are adaptable to various sizes, and are known for their cost-effectiveness. The process involves inserting the bore gage into the hole, checking if the diameter aligns with the target size, and noting the measurement. Accurate results depend on matching the bore gage to the hole size and using the correct measurement techniques.
