Abstract
A multi-cutting-edge diamond composite includes a columnar hard alloy substrate and a diamond composite layer, the diamond composite layer being disposed at a top end of the hard alloy substrate, wherein a circumferential edge of a top end of the diamond composite layer is provided with at least two segments of different chamfers to form different cutting edges. By providing different chamfers on the circumferential edge of the top end of the diamond composite layer, multiple cutting edges are formed in the circumferential direction of an end face of the diamond composite, such that different edges of the same composite sheet have different attacking abilities and impact resistance abilities. Since the chamfers form various cutting edges with different properties, the same diamond composite can meet the requirement of drilling in different strata, and can enable a diamond drill bit to adapt to the requirement of drilling in complex strata.
