Product Description

Product Description

Casing & Casing Shoe Bits are used for standard drilling down or positioning casing tubes into drill holes.

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.
