Abstract:
The present invention provides non-planar cutting tooth and a diamond drill bit. The non-planar cutting tooth and the diamond drill bit have great ability of impact resistance and balling resistance. According to the features of drilled formation, cutting teeth are arranged on the drill bit with different mode, which can improve the mechanical speed and footage of the drill bit.

Claim (Index 1):
A cutting tooth comprising\n a cylindrical body,\n wherein the surface of the end portion of the cylindrical body is provided with three cutting ridges, \n wherein the inner end of each of the cutting ridges extends to a triangle at the vertex of a Reuleaux triangle at the end portion of the cylindrical body, \n wherein the outer end of each of the cutting ridges extend to the outer edge of the surface of the end portion of the cylindrical body, \n wherein the surfaces of the end portion of the cylindrical body on each side of each of the cutting ridges are cutting bevels; and \n three cutting points, each located at the triangle at the vertex of a Reuleaux triangle at the end portion of the cylindrical body.
