摘要: A strike tip for a pick tool, comprising a strike structure joined to a substrate at an interface boundary, the strike structure comprising super-hard material and the substrate comprising carbide material. The strike structure has a strike end opposite the interface boundary, the strike end including a rounded apex having a radius of curvature in a longitudinal plane of at least 3.2 mm and at most 6 mm.
