DTH

DTH Hammers

DTH (Down The Hole) Hammer is a rock drilling tool which generates impacts at the bottom of the hole during the drilling process. The air passes through the drill pipe and enters the Hammer, pushing the piston to impact the DTH bit directly to drill. The air is then discharged from the DTH bit to bail the rock cuttings from the bottom of the hole.

DTH Bits

Shareate offers a range of DTH hammers and bits intended for drill and blast production mining, water well drilling and geotechnical construction projects. Powerful and efficient hammers, coupled with Shareate’s proprietary carbide insert technology ensure a high rate of penetration and the longest bit life is achieved in even the toughest of formations.

Bit Face Selection

Shareate offers 4 types of bit faces

Drop Centre Face

The drop centre face design is best suited to the soft-medium hard formation, and formation with broken layers. The drop centre bits have good penetration rate, and low hole deviation.

Flat Face

The flat face bits are general-purpose bit suitable for drilling extremely hard and abrasive rocks formation with high air pressure. Flat face bits have good penetration rates and good erosion patterns on bit body.

Concave Face

Suitable for most rock formations, especially in medium-hard and homogeneous rock formations which have the best effect. The face feature help to reduce deviation of boreholes and allows good cutting flushing on bit face.

Convex Face

The convex face is suitable for drilling soft-medium hard rock formations under low-medium air pressure. It is designed for the fast penetration rate in soft-medium ground formation with a good wear profile, but it has less control over hole deviation.
