摘要： A rigid composite structure includes a tubular body made from a metallic material and having a first bore formed therein along a longitudinal axis, and one or more segments formed from a super hard material disposed within the first bore. Each segment has a hole formed in the center thereof, and the segments may be positioned end-to-end and adjacent to one another to align the center holes about the longitudinal axis and form a second bore. The segments can be held under compression within the first bore of the tubular body. The segments may be made of super hard materials such as natural diamond, synthetic diamond, polycrystalline diamond, single crystalline 10 diamond, cubic boron nitrate or other superhard composite materials which exhibit low thermal expansion rates and are generally chemically inert. The resultant rigid composite structure may possess higher tolerances to high pressures and high temperatures within the second bore.

The working portion has an impact tip brazed to a working end of a carbide extension. The carbide extension has a cavity formed in a base end that is adapted to engage with a shank and a locking mechanism of the shank assembly. The shank has an outer surface proximate a first end which is receivable within the cavity of the carbide extension. The locking mechanism has a radially extending catch configured to engage with the cavity and couple the shank assembly to the working portion. The shank has an outer surface proximate a second end which is adapted to be press-fitted within a recess of a driving mechanism.

摘要： In one aspect of the invention, a tool has a working portion with at least one impact tip brazed to a carbide extension. The carbide extension has a cavity formed in a base end and is adapted to interlock with a shank assembly of the cutting element assembly. The shank assembly has a locking mechanism adapted to interlock a first end of the shank assembly within the cavity. The locking mechanism has a radially extending catch formed in the first end of the shank assembly. The shank assembly has an outer surface at a second end of the shank assembly adapted to be press-fitted within a recess of a driving mechanism. The outer surface of the shank assembly has a coefficient of thermal expansion of 110 percent or more than a coefficient of thermal expansion of a material of the driving mechanism.

摘要： 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.
