Diamond Surface Set Core Bits  
PQ3 Surface Set Core Bit For Soft Formation Boart Longyear Wireline Diamond Core Drilling
PQ3 surface set diamond core bit, suitable for relatively soft and fractured formations. 


Description: 
1. Surface set diamond core bit is primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bit.
2. It is also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.
3. 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. 


 

Q Wireline System

The Roschen™ Genuine Q wireline system represents proven technology in surface and underground applications. Our systems Q, QTK and Q 3 are designed to increase core recovery and productivity in any drilling condition, delivering greater efficiencies and reliability to the driller. Whether drilling a standard DCDMA hole or a project requiring a split tube to retrieve soft, highly fractured formations – the Genuine Q wireline system is proven to perform.


   

Q Coring Bits

Roschen™ Genuine Q bits are designed to support and operate with our Q wireline systems Q, QTK and Q 3. Roschen™ offers the most accepted bit range in the industry and has dedicated itself to the continued development of diamond bit technology. Our customers see it in our recent designs - such as the patented stage and the new Surface Set XP - they trust us to deliver unmatched productivity year-after-year.
