Abstract
A depth of cut control (DOCC) assembly includes a DOCC element positioned in a retainer pocket along a drill bit blade to limit a depth of cut of one or more fixed cutters. A retention member initially retains the DOCC element within the retainer pocket at a first exposure position. The retention member is configured to release the DOCC element downhole to allow one-way movement of the DOCC element to a second exposure position.
