PICK TOOL
A tip for a degradation tool, the tip comprising a PCD structure (20) joined to a cemented carbide substrate (30); the PCD structure comprising a plurality of strata (24, 25) arranged so that adjacent strata have alternating compressive and tensile stress states, adjacent strata comprising different PCD grades and being directly bonded to each other by inter-growth of diamond grains; each stratum having a mean thickness of at most 500 microns; the PCD structure defining a working end including a rounded conical apex (22) having a radius of curvature of 1.3 mm to 4 mm.
