Product Description

Product Description

Casing shoes are used for drilling down or positioning the casing tubes in a borehole.

Casing shoes have cutting elements on the face of the crown and outside diameter, while the inside diameter is smooth. The inner diameter of the casing shoe is sufficiently large to permit free passage of drill bits and core barrels in corresponding sizes.

For installing casing in soil, clay and other soft materials Tungsten Carbide Casing Shoes are the most economical choice. For installing casing into harder materials Diamond Impregnated Casing Shoes are the best choice.

We use only the best quality materials in all our casing shoes. Our grade of Tungsten Carbide has a very high wear resistance and high Transverse Rupture Strength (TRS), meaning that TC inserts are less prone to chipping and fracture.

Depending on the cutting media, we make four types of Casing & Casing shoe & Rod Shoe Bits:

---Impregnated Diamond Casing & Casing shoe & Rod Shoe Bits
---Surface set Casing & Casing shoe & Rod Shoe Bits
---Tungsten Carbide Casing & Casing shoe & Rod Shoe Bits
---Electroplated Diamond Casing & Casing shoe & Rod Shoe Bits

Casing Shoes are manufactured in all regular Metric and DCDMA Casing sizes.
