NW HW Diamond Casing Shoe Diamond Core Bit Durable Impregnated

NW HW Diamond Casing Shoe Diamond Core Bit , Durable Impregnated Diamond Core Drill Bit

Application

Casing shoes and rod shoes are designed to drill in casings or rods in difficult over burden material to position the rods or casing in the drilling hole.

The interior is smooth and sufficiently large enough to allow free passage of coring equipment such as bits, reaming shells, core barrels and drill rods.

They are manufactured to withstand difficult drilling conditions: for example, unconsolidated overburdened or broken abrasive materials.

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

Casing Shoe Bit
The inside diameter of the casing shoe bit is not set with diamonds sometimes(surface set Type) and flush with the inside diameter of the casing. Basically,the corresponding size of Drill Bits and Core Barrels have to get through the inner diameter of the casing shoe bits freely.

Casing Bit

The inside diameter of the Casing Bits are set with diamonds and is smaller than the Casing Shoe Bits. It will not permit the passage of the core barrel.

Characteristics

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
