  • Method of forming a diamond drill bit element using

    A method of forming a substantially hemispherically shaped diamond cutting element for use in a rotary drill bit is provided. A natural diamond is obtained and then cleaved to form a planar surface. A portion of the diamond is trimmed in the shape of a first truncated cone by directing a laser toward the planar surface from a predetermined angle and rotating the diamond in a circle about the central axis.

  • Low-load diamond drill bits for subglacial bedrock sampling

    The rotation of the drill bit causes the exposed cutting element to cut into the rock mass. Diamond drill bits require higher rotational speeds to achieve an acceptable pene- tration rate than other types of coring drill bits. The recommended rotational velocity of the OD of diamond bits is 140–240 m min–1(Core Drilling Tools, 2011).
