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 |
