"The problem with any gage functioning as intended has to do with the cleanliness of the parts. Residual oil or machining swarf though extremely small, can simply interfere with parts passing thru the gage.\n\nIf a part has any contamination and is at the high end of the tolerance range, any bit of dirt or even too much oil, the part will not enter. Sometimes if the part is aluminum, galling will occur once the high polished surface finish is worn or burnished. This galling or sticking of material on the ring gage surface can be removed by re-lapping the gage with extremely fine compound, a cotton bob with lapping compound, will generally suffice.\n\nCarbide and ceramic generally wear the same, that is about 20 times longer than steel, depending on the material being gaged and the cleanliness of the parts. It all comes back to the cleanliness of the parts."
