Cutting element with improved polycrystalline material toughness and method for making same

摘要

A cutting element having a cutting table made from sheet segments of commingled ultra hard material and binder. Each segment may be made from a finer or a coarser grade of ultra hard material or from different types of ultra hard material. The segments are aligned side by side over a cutting face of the cutting element to form the cutting table. The material grade and/or the material type of each segment may alternate across the cutting face.
