    摘要： A pick tool comprising a strike member non-moveably attached to a pick body, the strike member comprising a strike structure. The strike structure comprises super-hard material and defines a planar strike surface, the strike surface defining a cutting edge that includes an apex in the plane of the strike surface. The thickness of at least a proximate volume of the strike structure adjacent the cutting edge is at least about 2 millimetres.

    摘要： A pick assembly is provided, comprising a bit assembly and a holder assembly; the bit assembly comprising a bit support body, a fastener mechanism and a deflectable member, cooperatively configured such the deflectable member can be deflected responsive to the progressive coupling of the bit support body to the fastener mechanism. The holder assembly comprises a holder body and is configured for accommodating and retaining the bit assembly by interference means. The holder assembly and bit assembly are cooperatively configured such that the retention of the bit assembly by the holder assembly by interference means can be progressively increased responsive to the progressive coupling of the bit support body with the fastener mechanism when the bit assembly is accommodated by the holder assembly, operative to prevent substantial movement of the bit support body relative to the holder body in use.
