Product Overview

CRL Countersinks were specifically designed to cut round countersunk holes in aluminum. They cut faster than standard countersinks and leave a finished hole every time. Smooth drilling action from single cutting edge prevents chatter and fluted edges. The 1/4" (6 mm) shank diameter fits any 1/4" or 3/8" (6 or 10 mm) drill chuck.
