Abstract

A drag bit (10) having cutting elements (18), wherein the cross section of the cutting elements (18) is an oval shape, wherein in one embodiment the major axis is perpendicular to the surface of the drag bit blade (14). A method is also included, wherein the method comprises using a milling bit (32) having an oval cross section that thereby produces pockets (30) in the drag bit blades (28) for receiving the oval shaped cutting elements. Use of the oval bit also results in a half oval formed at the closed end of the pocket.
