The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece. They also have a Whistle Notch shank, which has self-clamping capabilities to help prevent the bits from slipping in the drilling machine when drilling at high speeds or under heavy loads.
