Abstract
A tool for friction bit joining a workpiece material includes a bit with a tapered pin and a non-cutting tip. The bit has a top surface opposite the pin with at least one feature recessed in, or extending from, the top surface and configured to transmit torque to the bit to rotate the bit around a rotational axis.
