Application:
It is used in geological exploration, coalfield mining and can be
used in a variety of models to extract cores and samples from
various complex rock formations.
Advantage:
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.
Packing:
• Wooden case.
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.
