Abstract

Det omtales et PCD-kutteelement (2010) som har en skive av superhardt materiale (2022) bundet til et substrat (2024). Det superharde materialet har en første endearbeidsflate og en mellomliggende periferisk arbeidsflate (2028) tilstøtende substratet. Et hulrom (2002, 2004, 2006) er utformet i substratet i et område umiddelbart tilstøtende den periferiske arbeidsflaten for å fremvise en andre endearbeidsflate. En særlig fordelaktig bruk av dette nye PCD-kutteelementet er som kutteelementer for borekroner til boring i jorden.
