We offer a complete range of casing and rod shoes, manufactured to reach the rock quickly and, as a result, start the real work promptly. With a robust design, casing and rod shoes are manufactured from quality synthetic diamonds, which is also used to manufacture core bits. Their interior and exterior diameters are reinforced and keep their same dimensions in abrasive conditions.
Our casing and rod shoes are manufactured to handle a broad range of conditions, from unconsolidated overburden to broken, abrasive formations. Impregnated standard and heavy duty casing shoes are stock items. Surface set casing shoes are available, but require longer.
