Abstract
This disclosure relates to a system for removing road material. In an embodiment, the system may include a milling drum and at least one pick mounted on the milling drum. Furthermore, the pick may include polycrystalline diamond at least partially forming one or more working surfaces of the pick.
Claims20
A pick for removing a road material, the pick comprising:
- a pick body;
- and
- a plurality of polycrystalline diamond compacts (“PDCs”) attached to the pick body, at least one of the plurality of PDCs comprising:
- a diamond table having a domed working surface;
- and
- a substrate comprising a first cylindrical portion attached to the pick body, the first cylindrical portion exhibiting a cylindrical shape with a distal planar surface, the cylindrical shape having a diameter that is greater than a thickness of the substrate, the diamond table being mounted on and being at least partially laterally encompassed by the distal planar surface of the substrate, the substrate defining a second working surface including the distal planar surface, wherein the domed working surface borders and protrudes from the second working surface of the substrate, wherein the domed working surface is positioned directly adjacent to the distal planar surface of the substrate.

A method of removing road material, the method comprising:
- advancing a plurality of picks toward the road material, at least one of the plurality of picks including:
- a pick body;
- and
- a plurality of polycrystalline diamond compacts (“PDCs”) attached to the pick body, at least one of the plurality of PDCs exhibiting a domed working surface at least partially laterally encompassed by and fixedly coupled to a second working surface;
- and
- advancing the domed working surface of the at least one pick into the road material;
- at least partially rotating the domed working surface and the second working surface fixedly coupled thereto together in unison relative to the pick body as the domed working surface contacts the road material;
- and
- failing at least some of the road material with at least one of the domed working surface of the at least one of the plurality of PDCs or the second working surface.
