摘要：
The present invention is a drilling system for cutting flat bottomed holes in work pieces. The tool has two opposing angled cutting edges (62, 64) extending upwardly to create an overlapping web (70) at the center. The angle at which the inner portion of the cutting edge (62, 64) is inclined is increased to create a center point on the cutting surface of the tool. The cutting edge (62, 64) has a rake surface with a positive rake angle (80) that lessens the forces on an insert (35), and also allows for better formation of chips of stock material being removed. Chip breakers (82) can be cut into the cutting edges (62, 64) of the insert (35), further aiding in the removal of stock material.
