FAQS

There are three possible ways in which to set a bore gage. The first method of setting a bore gage is to use a micrometer. While often the most convenient method, using a micrometer to set a bore gage is the least accurate way to do so. When using a micrometer, the size of the bore is matched to the micrometer between the spindle and anvil, which is then used to set the zero point on the bore gage. A second method for setting a bore gage is to use setting rings. This is by far the most accurate way in which to set a bore gage. However, it is also the most expensive due to needing to buy a range of setting rings for different sized bores. When using a setting ring to set a bore gage, the zero point is set on the bore gage through matching it to the size of the setting ring. The third method of setting a bore gage is to use a bore gage setting kit. Not as expensive as having setting rings, using a bore gage setting kit provides a cheaper way to get accurate measurements. However, using gage blocks in this process requires a bit more skill and a great deal more time. When using a bore gage setting kit to set a bore gage, you first wring together the required gage blocks and set the bore gage using them as a reference point for zero.
