Solid PCD cutter |
| 摘要 |
A cutting element may be formed by placing a plurality of diamond particles adjacent to a substrate in a reaction cell and subjecting the plurality of diamond particles to high pressure high temperature conditions to form a polycrystalline diamond body. The polycrystalline diamond body may have a cutting face area to thickness ratio ranging from 60:16 to 500:5 and at least one dimension greater than 8 mm. |
