These are a range of gauges that are used to measure a bore's size, by transferring the internal dimension to a remote measuring tool. They are a direct equivalent of inside calipers and require the operator to develop the correct feel to obtain repeatable results.
The gauges are locked by twisting the knurled end of the handles, this action is performed to exert a small amount of friction on the telescopic portions of the gauge (the smaller diameter rods found at the T head of the gauge). Once gently locked to a size slightly larger than the bore, the gauges are inserted at an angle to the bore and slowly brought to align themselves radially, across the hole. This action compresses the two anvils where they remain locked at the bores dimension after being withdrawn.
The gauge is then removed and measured with the aid of a micrometer or vernier caliper.
* Measuring Range: 5/16" to 6"
* A: 8mm to 12.7mm; 5/16" to 1/2"
* B: 12.7mm to 19mm; 1/2" to 3/4"
* C: 19mm to 32mm; 3/4" to 1-1/4"
* D: 32mm to 54mm; 1-1/4" to 2-1/8"
* E: 54mm to 90mm; 2-1/8" to 3-1/2"
* F: 90mm to 150mm; 3-1/2" to 6"
* Plunger on gauge expands in hole to be measured, locks in place and gauge is romoved from the hole. Final hole size is obtained by measuring over contacts with a micrometer.
* Contact Points are of hardened tool steel and precision ground on the end measuring radius.
* Constant spring tension for uniform feel.
* Rigid handle with self-centering feature.
