ABSTRACT:
A synthetic diamond cutter is disclosed for rock bits having a diamond cutting face at one end of a body supporting the cutting face. A heel portion is formed by the body near the diamond cutting face. The heel portion forms a groove depression or notch about adjacent to a cutting tip of the diamond cutting face. The cutting tip, as a result of the groove, results in a greater rate of penetration of the diamond cutting face due to a reduction of drag as the cutter works in an earthen formation or against a suitable workpiece.
