Product Description
Key Features
Function of the Casing Shoe – Aids in bedrock penetration, outer string seating, and fluid return sealing.
The casing shoes are threaded to the end of the outer drill string for penetration through overburden. It helps in seating the outer drill string into the bedrock, providing a tight seal for the drilling fluids to return to the surface

Casing shoe is used on the leading edge of a casing tube string to advance it through the overburden layer and into the bedrock by means of rotational drilling. Our standard design is Impregnated diamond casing shoe, which is the most commonly used due to its’ widest range of application and is generally the most efficient tool for advancing casing through overburden layers.
