As a hesitant buyer, I purchased a round center finder for my milling machine and I am pleasantly surprised by its efficiency. Industrial and Scientific use this tool to precisely locate holes with ease. As a result of my tests, I determined that it saves time and produces accurate results. The only downside is that it may take some practice to get comfortable with its use, but once mastered, it is a valuable addition to any toolbox.
Pros
Accurately and easily locates the center of round objects.
Cons
Not suitable for objects that are not round, limiting its versatility.
It is not possible to mark the center with a device. He needs a needle or stiff wire in the center stick to mark the center or give more specific instructions on how to use it.
I think the AV block works better. I tried using it on a tube that was in the AV block as a retainer and it hit the sides of the V block and not the tube. It can work well on a large pipe.
