Edmunds Gages master set discs are the finest in the industry.  There's no way around it.  Many view set discs as commodity items.  However, they are primarily used to "set" other types of gages so they have to be absolutely correct.  Our master discs are all made to the specifications of the American Gage Design (AGD) standards, and can be purchased with certifications directly traceable to the National Institute of Standards and Technology.   We offer inch or metric set discs from .150" (3.81 mm) to 12.00" (304.80 mm) in steel or chrome.   They are available in three styles, and in classes Z, Y, X, XX.  To request additional information Contact us.
