bull nose impregnate bits to penetrate a zone where core drilling
does not work
Roschen manufacture non core diamond bits, bull nose impregnate bits. These bits are also known as Bull Nose Bit.
When you are drilling loose, broken formations, faults, karst
caves, sometimes just after a period of drilling progress, when
lifting the drill rods, core barrel, because the loose broken
formation rock is loose, it is particularly easy to collapse. It is
necessary to use a bull nose drill bis or non coring bits to get
through this blockage and broken tooth.
As the name suggest these non core bits are manufactured for Non Core Drilling where core is not required.
