Owning a coaxial indicator is an excellent idea for any metrologist. These little tools are inexpensive compared to other precision measurement tools out there, but they provide a great deal of accuracy and precision. Simple to set up and use, there is no better way to measure the center point on a bore, shaft, arbor, hole, or anything else. Another advantage of the coaxial indicator is how straightforward it is to manually adjust. If your tool is slightly unbalanced or worn, the operator can disassemble the coaxial indicator, use a touch of light oil or smooth out the internal bearings to make it as good as new. Given the price of these tools, coaxial indicators are versatile measurement devices that are easy to operate, simple to maintain, and cheap to replace.
