Product details

       The new diamond DTH drill is a kind of drill that is used together with the DTH. The drilling work is carried out by the spline and the impactor. Made from high quality steel and cemented carbide as a raw material, a special heat treatment process allows a ball-bit to withstand the need for rock drills with a high degree of hardness and minimizes losses during energy transfer. Tooth evenly and not easy off tooth and off the tooth, so that the impact energy can be concentrated on the rock, to achieve efficient tunneling purposes. Mainly used for geological exploration, coal mines, water conservancy and hydropower, roads, railways, bridges, construction and construction.

WE can design and manufacture according to customers requirement of the bit diameter,the NO.of air holes,carbide buttons and the face shape.

Our Bit Face Shape Selection

Drop Center---For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures.Maximum hole deviation control.


Concave Face---The all-round application bit face specially for medium hard and homogenerous rock formations.Good hole deviation control and good flushing capacity.

Convex Face---For high penetration rates in soft to medium-hard with low to medium air pressures.It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons,but poor hole deviation control.

Double Gauge Face---This kind of face shape is suitable for fast penetration rates in medium to hard rock formation.Designed for high air pressures and good resistance to steel wash step gauge bit.


Flat Face---This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures.Good penetration rates an resistance to steel wash.
