VENTED BLANK FOR PRODUCING A MATRIX BIT BODY |
| 摘要 |
A vented blank may be useful in the production of a matrix bit body. A mold assembly for use in producing a matrix bit body may include a cavity defined within the mold assembly. A core and a matrix material are disposed within the cavity. A metal blank is disposed about the core and supported at least partially by the matrix material such that the metal blank extends above the matrix material. A vent extends from the metal blank, defining an annular space between the vent and the mold assembly. |
