Having made overhead concrete drilling easier with an innovative, upside-down drill press, Dr. David Rempel and his University of California, San Francisco research team have turned their attention to the physical demands of drilling horizontally and at other angles.
Their efforts have yielded a new universal drilling jig that is designed for dowel and rod work and drilling large-diameter, ¾-in. to 1.5-in. holes for anchor placement in rock and concrete.
