摘要： A drill bit includes a shank defining a longitudinal axis and a cutting edge extending radially outward relative to the longitudinal axis. The cutting edge is configured to remove material from a workpiece along a cutting path during a cutting operation. The drill bit further includes a plurality of scoring elements positioned within the cutting path and configured to contact the workpiece before the cutting edge during the cutting operation.
