Diamond Core Bits , Casing Shoe Bit UMX NW HW PW Flat Matrix Crown
1. High penetration rate
2. High core recovery ratio
3. long life of drilling service
Whatever form of casing is, casing shoe must be fitted on top of casing when put into drill hole. The edges of casing shoe exposed to rocks are very few. Casing shoes are connected with casing by means of thread. Outer diameter of casing shoe is same as bit’s,with its inner diameter equal to or slightly less than casing’s. Such design make it is possible for core tube, drill rod and core barrel to pass through in order to extend geological exploration
Main functions of casing shoe:
1): protect casing ends from distortion.
2): help casing pass through stratum to bed rock.
3): carry mud to earth surface.
4): help down-pass of casing when drill rod is in hole.
Available in multiple standard configurations and selected on the basis of relative rock hardness and ground conditions.
Reaming shell is used to protect drill bit,should couple the Impregnated diamond drill bit with the core barrel. It’s can set with natural or synthetic diamond, Polycrystalline diamond embedded in the circle side.Its main function is to ream the hole to the correct constant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one. It also acts as a stabilizer for drill bit.
