Home >> Diamond casing & casing shoe bits

diamond casing & casing shoe bits are designed for opening the hole, and for standard drilling down as well as positioning all sizes of standard casing tubes into certain drill holes. While diamond rod shoe bits are very similar to casing shoes bits, it differs in thread connections and are mainly used for wireline drilling rods.

Diamond casing shoe bits: The inner sides of casing shoe bits are NOT set with diamonds, it flush with the inside diameter of the casing. the corresponding size of core bits and core barrels can get through the inner diameter of the casing shoe bits freely.

Diamond casing bits: The inner sides of casing bits are set with diamonds, the diameter size is smaller than casing shoe bits, so that the core barrels can NOT get through.

Impregnated diamond casing shoe bits

impregnated diamond casing and casing shoe bits are made with the diamond grits distributed and embedded within a powdered metal bond into the core and matrix of the bit. The main composition of impregnated diamond casing shoe bits and rod shoes is a sintered powdered metal crown joined and blended into a steel tool body.

Surface set diamond casing shoe bits

surface set diamond casing and casing shoe bits are for openning the hole, diamond grits in 40/60 on bit crown, shape of semi-round with long life time and fast drilling speed. surface set diamond casing and casing shoe bits are featured with a layer of natural diamond normally on the active places of the bit crown on a particular predetermined pattern.

Electroplated diamond casing shoe bits

electroplated diamond bits are made of a cylinder bit which is electroplated with layers of synthetic diamonds. These casing and casing shoe bits are protected with electroplating and vacuum at the opening of the metal cylinder. Though it can be used up quickly, the power of penetration into the rocks is really great.

Tungsten carbide casing shoe bits

tungsten carbide casing and casing shoe bits are for openning the hole, have advantages in price and economical applications, suitable for soft to medium hardness rocks.
