20110303465 | IMPREGNATED DRILLING TOOLS INCLUDING ELONGATED STRUCTURES - Impregnated drilling tools include elongated structures that provide enhanced properties. The drilling tools contain a diamond-impregnated cutting section that contains elongated structures made from carbon, glass, ceramic, and the like.

Such higher modulus binders can cost less and allow for tailoring of the cutting section to retain the diamonds for the desired amount of time. As the cutting section erodes, the elongated structures may also increase the lubricity at the face of the cutting section. | 12-15-2011 |
