Abstract: A fixture for facilitating the accurate and repeatable preset of chamfering tool cutting inserts to proper height and angle specifications. The fixture may include an upright main body with a removable insert for receiving an end of a chamfering tool of interest. The insert may include several raised support pads for supporting the chamfering tool in an elevated position. The fixture may also employ chamfering tool clamping mechanisms to securely clamp the chamfering tool to the fixture. The clamping mechanisms may include a feature that allows for proper clamping pressure to be exerted on a given chamfering tool even if a flange portion thereof is somewhat thicker or thinner than expected. One or more locating pins or other locating elements may also be employed to ensure repeatable location of a chamfering tool to the fixture.
