AGD design
All ground surfaces are of hardened tool steel
Balanced design for easy one hand operation
Can be checked and set with an optional setting master
Fast, accurate and easy to read
Gage can be pressed down on a flat surface and checked so the size should read the same as the set number stamped on the back of the indicator
Holes that need to be accurately checked must have no chamfers or countersinks
