Rock Drilling Tools
Casing shoes are designed for casing-supported drilling operations to stabilize borehole walls in foundation piling and water well projects. Manufactured from low-carbon alloy steel with precision machining and heat treatment, they provide high strength, wear resistance, and reliable performance in demanding drilling conditions.
Widely used in various casing-supported drilling operations for borehole wall stabilization.

The following information is required: Outer diameter and wall thickness of the casing pipe; Large and small step diameters at the interface between the casing drilling system and the casing shoe. For threaded casing shoes, the casing thread specification is also required.
The difference mainly depends on whether precision machining and proper heat treatment are applied. These casing shoes are manufactured from high-quality low-carbon alloy steel and processed with a mature heat treatment procedure, resulting in strength and hardness that significantly exceed typical market design requirements.
