    摘要: In one aspect of the invention, an apparatus for directional degradation of a surface comprises an attachment assembly connected to a motorized vehicle comprising at least one degradation tool. The at least one degradation tool comprises a substantially cylindrical rotary degradation element having a substantially cylindrical working surface formed about a rotational axis. A plurality of cutting inserts is embedded within the substantially cylindrical working surface and is adapted to degrade a surface in a direction substantially normal to the rotational axis. At least one of the plurality of cutting inserts comprises a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The superhard material comprises a substantially pointed geometry with an apex comprising a 0.050 to 0.160 inch radius and a 0.100 to 0.500 inch thickness from the apex to the non-planar interface.
