Barcor has been manufacturing chamfer gages for almost 50 years and have been known for having the best quality chamfer gages in the industry. The chamfer gage is a specific type of precision measurement tool that is designed specifically to measure the the top(major) diameter of a chamfer, countersink or tapered hole. Chamfer gages are simple to use. A user would insert the spring-loaded gaging plunger into the chamfer or countersink, apply pressure, and the diameter of the chamfer is displayed on the dial.

The great part about Barcor chamfer gages is that there is no setting master required. There is a “set to” number stamped on the back of each chamfer gage. The user just need to press the base of the chamfer gage up against any flat surface and make sure the needle is pointing to the “set to” number that is on the back of the dial. If the gage is slightly off, the user can easily rotate the bezel of the gage until the needle is pointing to the “set to” number and then the chamfer gage is ready to use.
