CUTTING ELEMENTS CONFIGURED TO GENERATE SHEAR LIPS DURING USE IN CUTTING, EARTH-BORING TOOLS INCLUDING SUCH CUTTING ELEMENTS, AND METHODS OF FORMING AND USING SUCH CUTTING ELEMENTS AND EARTH-BORING TOOLS
Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting eleme...

| description | Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element. |
