Coaxial indicators are available in different sizes and measuring ranges, depending on the specific application. Some models are designed with additional features, such as adjustable arms or interchangeable tips, to increase their versatility and functionality. Overall, coaxial indicators are a valuable tool for anyone who needs to make precise measurements of cylindrical surfaces or objects.

Coaxial indicators are often used in manufacturing and machining industries, where precision measurements are critical to ensure the quality of the final product. They are particularly useful for measuring the concentricity of two cylindrical objects, such as a shaft and a bearing or a piston and cylinder, as well as for checking the alignment of drilled holes and bores.
