PQ Wireline Diamond Core Drill Bits

PQ Wireline Diamond Bits Impregnated Tube Core Bits Core Drilling Tools

 
Product information: 
 
Core diamond drilling tool for drilling rock in underground soil formations which includes an outside pipe and an inside pipe therein that can be conveyed separately to the surface.
The inside pipe includes a core-receiving receptacle at its lower end, and at its upper end is provided with a measurement unit for on-site acquisition, processing and storage of data, such as borehole, core and/or drilling process parameters.
 
Application:
 
Core drilling bits are mainly tools used to drill holes in steel plates and other products, hollow core bits are used in conjunction with machines that are specifically on core drilling bits. Thin-walled diamond core drill bits: concrete core samples are drilled directly into the structural concrete and processed for compressive strength testing, this method is recognised as a more intuitive and reliable test method for testing the strength of concrete

Advantages:

Surface-Set diamond bits are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are 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.
