Abstract
A metal cutting drill includes a steel drill body, and a carbide insert brazed therein. The drill body includes a front face having a recess formed therein, the recess radially overlapping a longitudinal axis of the drill body. The insert is brazed in the recess and includes a plurality of spaced-apart cutting edges disposed on opposite sides of the axis. The cutting edges radially overlap during a drilling operation. One of the cutting edges projects radially outwardly beyond a side face of the head, and another of the cutting edges terminates radially inwardly of the side face.
