摘要： An insert (10) for a cutting tool (100) for use down a well bore comprises a body of a hard material (tungsten carbide) suitable for cutting steel. The body is shaped for formation in a mould that comprises a die (70) and first (74)and second (78) punches and arranged so that the first punch can eject the body after formation from an opening of the die closed during formation by said second punch. The insert has first (12) and second (14) ends whose faces are defined, at least in part, by corresponding faces of the first and second punch. Between them is a longitudinal axis (24) of the insert. The area of the first end is less than the area of the second end. The body has flanks (16) that form ridges (18) extending between the first and second ends. The ridges form cutting edges of the insert. They are separated by V-shaped troughs (20) of said flanks. The ridges taper and spiral about the axis.
