High Penetration Surface set Diamond Core Drill Bit For Stone , BQ NQ HQ PQ Size
This type of bit is primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit. It is also recommended for use in drilling harder formations where the available rotary speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.
In most cases, surface set diamond bits will provide higher rates of penetration than in softer formations due largely to the greater degree of exposure of the individual diamond crystals.
To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.

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.
tepped 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.
