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 insert comprises a substrate (40), a layer of ultra-hard abrasive material (52) bonded to the substrate and presenting a primary cutting edge (54) for the tool insert, and a protective layer (56) bonded to the ultra-hard abrasive material so as to protect the primary cutting edge thereof. The protective layer provides a secondary cutting edge (58) 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 a window through a first substance, such as a casing or lining of a borehole or shaft, but to expose the primary cutting edge upon encountering a second substance, such as a rockbed. The invention extends to a method of drilling a horizontal or angled hole in a subterranean rock formation using a rotary drill string and bit incorporating a tool insert of the invention.
摘要翻译：工具插入件包括基底（40），结合到基底的超硬研磨材料层（52），并且呈现用于刀具插入件的主切削刃（54）以及粘合到超高分子量的保护层（56）硬磨料，以保护其主切削刃。保护层提供用于工具插入件的辅助切割边缘（58），保护层的深度被选择为足以保护主切削刃，同时通过第一物质切割，铣削或钻孔，例如钻孔或轴的套管或衬套，但是在遇到第二物质（例如岩石）时露出主切割刃。本发明延伸到使用旋转钻柱钻头和钻入本发明的工具刀片的钻头来钻探地下岩层中的水平或倾斜孔的方法。

摘要： An abrasive product which comprises a polycrystalline mass of self-bonded abrasive particles of irregular shape, the product being substantially free of a second phase and containing substantial plastic deformation of the abrasive particles. The abrasive particles are preferably diamond or cubic boron nitride and the plastic deformation of the particles is preferably at least 0,3 percent. The abrasive product may be made by subjecting a mass of the particles to elevated temperature and pressure conditions.
摘要翻译：一种研磨产品，其包括具有不规则形状的自粘合磨料颗粒的多晶团块，该产品基本上不含第二相并且包含磨料颗粒的大量塑性变形。研磨颗粒优选为金刚石或立方氮化硼，并且颗粒的塑性变形优选为至少0.3％。研磨产品可以通过使大量颗粒经受高温和高压条件而制成。
