  • Patent number: 7641002
    Abstract: In one aspect of the present invention, a rotary drag drill bit has a body intermediate a shank and a working face. The working face has a plurality of blades converging towards a center of the working face and diverging towards a gauge of the working face. A carbide section is fixed to the working face and positioned within a pocket disposed within an inverted cone of the working face. The carbide section has a distal end exposed within the working face.

  • Patent number: 7628233
    Abstract: A degradation assembly has a carbide bolster brazed within a hole formed in a surface. The bolster has a substantially straight cylindrical portion mostly disposed below the surface and a top end and a bottom end. The top end narrows from the cylindrical portion with a substantially annular concave curve to a planar interface adapted for bonding to a carbide substrate and the bottom end narrows from the cylindrical portion to a stem which bottoms out on a geometry of the hole.
