COP SERIES DTH hammer products offers a wide range of quality, versatile DTH hammers to interchangeable, or replace a number of leading industry manufacturers. Hammers are available for down hole and blast hole, water well, gas, mining applications and use in nearly all ground conditions.
The drill bit is paired with the corresponding hammer (hole diameter and spline configuration).Customers can customize their drillhole bits in various ways, such as changing tungsten carbide inserts (ball, trajectory, etc.), surface profiles (plane, concave, convex, etc.) and flushing holes.
The drill hole impacter is connected with the drill bit for drilling engineering.Using high quality steel and optimal horizontal alloy steel as raw materials, special heat treatment process and advanced cemented carbide insert technology enable the bit to function well even in hard rock strata, and save energy at the same time.
Carbide conical teeth, with this kind of alloy tooth shape of the DBM is suitable for sedimentary layer and broken layer more rock, mainly because of the sharp shape of the carbide cone teeth, working with the rock contact area is small, small resistance.
Under the same working conditions, it is easy to invade the rock and the driving speed is fast.
However, due to the thin volume of the conical tooth, the bending and torsion resistance of the alloy tooth is relatively poor, and the exposed height of the fixed tooth is relatively high.
Large bending moment will be produced when working.
The alloy teeth are easy to break off. The test shows that the working pressure of the taper teeth is below.
The hardness of rock is used in the working environment of Platt F =14, no fissure interlayer and good geological structure, and the economic and technical indexes are obvious, and the advantages of its structure can be given full play.
