The Fowler 52-646-600 Xtra-Range dial bore gage give you that extra measuring range you need as most dial bore gages only go up to a 6" diameter. The two-point contact allows users to measure their parts or cylinders and easily check for ovality or out of roundness. The Fowler dial bore gages are great quality but have to be set to a master prior to use. Setting rings are the best and most accurate way to set/calibrate a bore gage before using but setting rings can expensive if you are measuring multiple bore sizes.
