A recently granted patent (Publication Number: US11926972B2) discloses a unique pick designed for removing road material. The pick comprises a pick body and a plurality of polycrystalline diamond compacts (PDCs) attached to the pick body. One of the PDCs features a diamond table with a domed working surface mounted on a substrate with a cylindrical shape. The domed working surface protrudes from the substrate, positioned directly adjacent to its planar surface. The pick body is configured to be mounted in a holder or mounting base of a milling drum, with the PDCs exhibiting various shapes and sizes, aligned along a reference line parallel to the substrate's surface.

Furthermore, the patent also describes a method and system for removing road material using these innovative picks. The method involves advancing the picks towards the road material, with the domed working surface of at least one pick rotating and engaging the material to facilitate its removal. The system includes a milling drum with multiple picks, each equipped with PDCs featuring domed working surfaces for efficient material removal. The picks are mounted on the drum, with the pick body designed to align with the drum's holder or mounting base. This patented technology aims to enhance the efficiency and effectiveness of road material removal processes, offering a novel solution for industries involved in road construction and maintenance.
