Estimating the term…
A cutting element for use on a rotary-type earth boring drill bit for drilling subterranean formations including a segment and a support member. The support member is preferably fabricated from a tough and ductile material, such as iron, an iron-based alloy, nickel, a nickel-based alloy, copper, a copper-based alloy, titanium, a titanium-based alloy, zirconium, a zirconium-based alloy, silver, or a silver-based alloy. A bit attachment portion of the support member is securable to a bit body. A segment-receiving portion of the support member is disposable within a recess formed in the segment to secure the segment to the bit body and support the segment during use of the drill bit. Preferably, the segment is fabricated from a hard continuous phase material that is impregnated with a particulate abrasive material, such as natural diamond, synthetic diamond, or cubic boron nitride. The continuous phase material and abrasive material may be aggregated by sintering, hot isostatic pressing, laser melting, or ion beam melting.
