HIGH IMPACT RESISTANT TOOL WITH AN APEX WIDTH BETWEEN A FIRST AND SECOND TRANSITIONS |
摘要 |
In one aspect of the present invention, a high impact resistant tool comprises a sintered polycrystalline diamond body bonded to a cemented metal carbide substrate at an interface, the body comprising a substantially pointed geometry with an apex, the apex comprising a curved surface that joins a leading side and a trailing side of the body at a first and second transitions respectively, an apex width between the first and second transitions is less than a third of a width of the substrate, and the body also comprises a body thickness from the apex to the interface greater than a third of the width of the substrate. |
