High quality HQ3 Surface set diamond bit /core drill bit for soft formations
SURFACE SET CORING BITS
Surface set coring bits are typically used for higher penetration rates than impregnated bits in softer formations. They utilize a single layer of natural diamonds set in a hard matrix.
The choice of a Surface Set Bit will be dictated by the rock type. The diamond size, crown design and matrix hardness used will be determined by the hardness of the formation. The friability of the core will determine the type of fluid passages. The surface set bit provides a greater exposure of diamonds than the impregnated bit and therefore faster penetration in soft formations.
Face Profiles of surface set core bit:
Semi-round: it is mostly used in the core bit with bit kerf thickness less than 11mm. It can drill various formations. The core bit with semi-round profile has long bit life, and can avoid damage; while the bit kerf thickness is over 11mm with semi-round profile can be applied in drilling abrasive formations.
Stepped profile: core bit kerf thickness over 11mm usually has this kind of profile. Bit with Stepped profile can obtain high penetration rate with good stability in drilling. However, it is not recommended in fractured very abrasive formations. When the core bit of bit kerf less than 11mm has stepped profile can facilitate drilling speed and have better drilling stability.
