摘要： A tool insert comprises a substrate (10) having a support surface and a support ring extending laterally from the support surface. The support ring is sized to define a recess (14) within the confines thereof and a shelf about the periphery thereof. A layer (12) of ultra-hard abrasive material is located within the recess and bonded to the substrate and the support ring (16), and presents a primary cutting edge (22) for the tool insert. A protective layer (18) is bonded to the shelf about the support ring so as to protect the primary cutting edge. The protective layer provides a secondary cutting edge (20) for the tool insert, the depth of the protective layer being selected so as to be sufficient to protect the primary cutting edge whilst cutting, milling or drilling through a first substance but to expose the primary cutting edge upon encountering a second substance.

摘要： A tool component, which is typically a cutting element or a gauge stone in a rotary drill bit, comprises a layer of ultra-hard abrasive material bonded to a substrate, the layer of ultra-hard abrasive material comprising a pair of opposed end surfaces, an upper surface defined between the end surfaces, and at least one curved and tapered cutting edge defined at the intersection of the respective end surfaces and the upper surface. The respective cutting edges of the tool component and the respective end surfaces leading to the cutting edges are generally wedge-shaped, the upper surface of the layer following generally the same or a similar profile, at least in the region of the cutting edges.

摘要： A composite part comprises (a) a cutting element which comprises super-hard cutting table and a substrate and (b) a metal or alloy layer. Respective first surfaces of the superhard cutting table and the substrate are joined to each other, and the metal or alloy layer is located adjacent to second surfaces of the cutting table and the substrate so as to surround the joined first surfaces of the cutting table and the substrate. The metal or alloy layer and the second surfaces of one or both of the cutting table and substrate are co-operatively shaped substantially to prevent relative movement therebetween. The metal or alloy layer may be used to secure the cutting element within a tool body, and advantageously provides a convenient means to effect that securement, while simultaneously protecting the join between the superhard cutting table and the substrate during the process of securement of the cutting element to the tool body.
