Diamond core drill
FIT's Impregated Diamond Core Bits are manufactured with very small,high quality synthetic diamonds, mixed evenly through a metal alloy matrix.
In most geological formations, impregnated bits are more economical to use than other bits.
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.

Features:
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.
Principle of choosing diamond size--the harder the rocks, the smaller the diamond size should be.
Diamond Size | Formation Drilled |
10/20 SPC* | Soft formation |
20/30 SPC | soft to medium formation |
30/40 SPC | medium formation |
40/60 SPC | Medium to hard formation |
< 60/80 SPC | Very hard formation |
*SPC is short for Stone per Carat **40/60 is FIT standard diamond size for natural diamond core bit ***Other sizes are available as per request |
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.
