METHODS OF MANUFACTURING BIT BODIES |
摘要 |
A method for manufacturing a drill bit includes coupling displacements to a mold with a series of attachment members, filling a cavity of the mold with a material, and heating the material to form a bit body of the drill bit. The method may also include removing the displacements to expose cutter pockets in the bit body and coupling cutting elements to the cutter pockets. |
