- These gages directly measure the diameter of chamfered holes. No setting master is necessary.
- When the three-blade plunger is pressed against a flat surface, the gage should read the set number stamped on the back of the indicator. In case of wear, the gage may be adjusted to read the proper number.
- All ground surfaces are of hardened tool steel. Indicators are AGD design.
- Internal gages will measure the largest diameter of any chamfer that has an included angle within the range of angles printed on the dial face of the gage.
- External gages will measure the smallest diameter of any chamfer within the range of angles printed on the dial face of the gage.
- External gages are available as a special order product.
