Go farther in abrasive formations
Impregs are ideal for drilling abrasive formations because of their self-sharpening cutting structure that replenishes itself as the bit wears. Impregnated bits utilize sharp, grit-size diamonds sintered directly into a tough tungsten carbide matrix.

The matrix is formulated to match the application so the carbide matrix wears slightly faster than the diamond. This ensures fresh, sharp diamonds are exposed at the optimal rate for maximum ROP and bit life.

HedgeHog impregs
Featuring an aggressive, balling-resistant cutting structure, optimized hydraulics and advanced matrix material, HedgeHog impregs have an interrupted cutting structure and optimized blade count that allow the bit to take a bigger bite out of shale formations.

Full-scale simulator tests
When drilling sandstone in full-scale lab simulator tests, the HedgeHog design matches the performance of a standard impregnated design.  When testing in shale, HedgeHog drills 30 percent faster.
