BIT WITH CO-RADIAL CUTTING PROFILE AND CUTTING ELEMENT |
| 摘要 |
A cutting tool may include multiple blades extending from a bit body, and multiple cutting elements coupled to the blades. First cutting elements and a second cutting element coupled to the blades may collectively define a cutting profile of the bit. The second cutting element may be substantially larger than at least some of the first cutting elements and may substantially define a nose region of the cutting profile. |
