Which tool is typically used to find the center of a shaft or other cylindrical work?

The combination set is typically used to find the center of a shaft or other cylindrical work due to its versatility and range of functions. It consists of a ruler and various interchangeable heads that can be used for measuring angles and depths. When finding the center of a cylindrical object, the combination set can accurately measure across the diameter, helping to locate the midpoint. This capability is essential for precise machining and layout work, ensuring that subsequent operations like drilling or cutting are done symmetrically about the centerline.

Other tools listed, such as calipers and micrometers, while precise in measurements, are generally used for gauging dimensions rather than directly locating centers. A dial indicator, on the other hand, is useful for measuring variation and ensuring flatness or alignment, but it is not designed specifically for locating the center of cylindrical work. Therefore, the combination set is the most suitable tool for this particular task in cylindrical workpieces.
