Inspection ball kits are available from stock in the 14 most popular English sizes from 3/32" to 1.00", individually or all in a kit. Each individual group of balls contain a nominal fractional ball as well as one each of a +.002", +001", +0005", +0002", and -.001", -002". The inspection ball kits are also excellent for ball sizing parts. Ball sizing is basically pushing a ball through a hole or tube which produces a certain finish or size. We recommend our Sapphire Oil as a lubricant.
