摘要： A strike tip (100) for a pick tool, comprising a strike structure (120) joined to a substrate (110) at an interface boundary (115), the strike structure (120) comprising or consisting or super-hard material and the substrate (110) comprising or consisting of carbide material; the strike tip having a proximate strike end (117) coterminous with the super-hard material and a distal end (118) defined by the substrate (110), a side connecting the strike and distal ends; the strike end (117) including a flat apex area (150) and an outer area extending from the apex to the side. The apex area (150) is substantially less than the outer area, and is at least 1 square millimetre and at most 25 square millimetres.

摘要： A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.
