Dial Bore Gages

Dial Bore Gages are precision instruments used to measure the diameter of holes in various materials. They are commonly used in the automotive, aerospace, and machining industries to ensure that parts and components meet specific tolerances. These gages consist of a dial indicator mounted on a bar that is inserted into the hole being measured. The indicator has a contact point that rests against the wall of the hole, and as the bar is moved, the indicator needle moves to show the diameter of the hole.

Dial Bore Gages are available in a variety of sizes and styles to accommodate different hole diameters and depths. They can be used for both through holes and blind holes and are commonly used for measuring the internal diameter of cylinders, pipes, and other cylindrical components. Some dial bore gages also feature interchangeable anvils or contacts, allowing for greater versatility and accuracy in measuring different hole sizes and shapes.

Companies like Mitutoyo, Fowler, and SPI offer a range of Dial Bore Gages with varying levels of precision and features, from basic models for occasional use to high-end models for more demanding applications. Overall, dial bore gages are a critical tool for ensuring the quality and accuracy of machined parts and components.
