摘要： A high-impact resistant pick having a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide bolster. A bore formed in a base end of the carbide bolster is generally opposed to the front end. A steel body has a shaft extending distally from a shelf, and which shaft is fitted into the bore of the bolster at an interface. A shank adapted for connection to a driving mechanism extends proximally from the steel body opposite the shaft. A washer is disposed intermediate the base end of the carbide bolster and the shelf of the steel body.
