| 摘要 | Cutting elements for cutting tools comprise a pre-formed fracture plane disposed in at least one surface of the cutting elements. The pre-formed fracture plane can comprise a groove cut into one of the surfaces of the cutting element, or the pre-formed fracture plane can be formed by using a laser or other heat concentrating source to weaken a portion of one of the surfaces of the cutting element so that the cutting element will break along the pre-formed fracture plane. | ||||||
