Another example of such an infiltrated diamond body is a cast wrench jaw having at least one raised jaw pad.
Claims21
A tool comprising:
- a base portion;
- and
- at least one cast gripping portion, wherein the base portion and the at least one cast gripping portion are defined by a single infiltrated body, the infiltrated body being formed from a cast mixture, the cast mixture comprising:
- a matrix having a hard particulate material extending throughout the base portion and the at least one cast gripping portion;
- and
- a plurality of diamond particles dispersed within at least a portion of the hard particulate material;
- and
- a binder that secures the hard particulate material and the diamond particles together,
- wherein the diamond particles comprise between about 25% by volume and about 75% by volume of each cast gripping portion,
- wherein the tool is a gripping roller, and wherein the at least one cast gripping portion comprises a plurality of contact pads positioned on an outer surface of the base portion of the gripping roller, and
- wherein the base portion and the at least one cast gripping portion are cast together to form the infiltrated body.
8 more elements
A tool comprising:
- at least two jaws;
- and
- three gripping pads, each gripping pad of the three gripping pads positioned on one of the at least two jaws,
- wherein the tool is a wrench, and wherein each jaw of the at least two jaws and each gripping pad positioned thereon are defined by a respective infiltrated body, said infiltrated body being formed from a cast mixture, the cast mixture comprising:
- a matrix having a hard particulate material extending throughout said jaw and each gripping pad positioned thereon;
- a plurality of diamond particles dispersed within at least a portion of the hard particulate material;
- and
- a binder that secures the hard particulate material and the diamond particles together,
- wherein the diamond particles comprise between about 25% by volume and about 75% by volume of each cast gripping pad,
- wherein each jaw of the at least two jaws and each gripping pad positioned on said jaw are cast together to form the respective infiltrated body.
