A recent article on Concrete Fastening Systems website “Carbide Bits for Concrete Drilling Applications” touches on the value of standards and the confusion in the marketplace arising from non-standard drill bits. According to Michael Pistorino, “Many years ago, different manufacturers of anchors would manufacture anchors and bits to their own tolerances. This meant that carbide bits had to be manufactured and sold by a specific company. Confusion among customers resulted since different anchors were being used with different bits.”
A copy of the ANSI B212.15-1994 standard is available free from the CCPA, Cemented Carbide Producers Association, which serves as Technical Advisory Group for ISO/TC 29/SC 9, and is the Secretariat for the American Standards Committee B212. You can learn more about the work of the CCPA technical committees and how to become involved in standards activities.
