    摘要: An improved disc-shaped cutting element including first and second major flat surfaces and a cutting edge, said element comprised of a hard metal substrate defining an irregular interface bonded to a polycrystalline diamond, where said interface includes a plurality of concentric and redial grooves adapted to receive corresponding protrusions formed on the diamond layer so as to enhance wear like and impact resistance.
