RC Reverse Circulation Hammer DTH Drill Bits / RE545 Hammer Bits

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.


DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.

Characteristics of Reverse Circulation Bits:

1.Based on previous experience of ordinary hammers, combined with the features of reverse circulation hammer, optimized internal structure and ideal energy transfer, thus ensuring the series of hammers drilling with fast, smooth and continuous sampling.


2. The internal structure is very simple with components of high rigidity, thus ensuring long life and easy maintenance of the hammer.


3.The  collection  tube  adopts  an  integrative  design  and  can  be  replaced  without  disassembling  the  hammer.  With  carburizing treatment, it has good abrasive resistance.


4.Equipped with bits designed with patent. Simply by replacing the drill bit, the same hammer can drill holes of different sizes ensuring that the sample is not contaminated.


5. In difficult conditions such as loose soil, hard rock and plenty of water exists, sampling can be done well.
