Surface Set Diamond Core Bit for Broken and Abrasive Formation Rock

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.

To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.

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 standard diamond size for natural diamond core bit **Other sizes are available as per request

"Q" series: AQ, BQ, NQ, HQ, PQ/AQTK, BQTK, BQ3, NQ2, NQ3, NQTT, HQ3, HQTT, PQ3, PQTT
