Patent ID: 7707735

Claim:
A hole angularity gage comprising: a gage body with a proximal end, a distal end, and a central channel between the proximal end and the distal end; a contact disc positioned within the central channel, wherein the contact disc includes a central opening defined by an inner edge of the contact disc; a center pin that extends through the central opening of the contact disc; a tapered pin having a proximal end and a distal end, wherein a diameter of the distal end of the tapered pin is greater than a diameter of the proximal end of the tapered pin; a collet portion for accepting the distal end of the tapered pin, the collet portion being adapted to expand to a hole diameter; a hole probe adapted to rotate the center pin from a primary gage axis toward the inner edge of the contact disc; and an indicator adapted to activate when the center pin makes physical contact with the contact disc.
