Patent ID: 7878273

Claim:
A drilling stabilizer comprising: a tungsten carbide matrix body having a first end, a second end, and a longitudinal bore extending from the first end to the second end, wherein the tungsten carbide matrix body is formed substantially entirely from a matrix of tungsten carbide and one or more metal alloys; a plurality of tungsten carbide matrix blades integrally formed with said tungsten carbide matrix body and formed substantially entirely from the matrix of tungsten carbide and one or more metal alloys; and a metal tube disposed within the longitudinal bore, wherein the metal tube comprises a first connection disposed at the first end, a second connection disposed at the second end, and bore extending from the first connection to the second connection, wherein the tungsten carbide matrix body is adapted for withstanding compressive longitudinal forces along the axis, and wherein the metal tube is adapted for withstanding tensile forces along the axis.
