This method can make a ball on a shaft where the "angle" the ball makes is about 270º out of the 360º possible. The limit is largely the attachment hitting the chuck. It will also be noticed that to get this angle the ball has to be made a long way out from the chuck. To get the best possible result the left side of the cutter needs to be removed.

Confirming Dimensional Accuracy of a Precision Ball ...

As with most dimensional standards, the accuracy of a precision ball should be roughly 10 times greater than the resolution of the gage it is used to master, and the instrument used to measure the ball should be 10 times as accurate as they are. Consequently, a precision ball is commonly measured to microinches, or even fractions of microinches.
