Atlas Copco Down The Hole DTH Drill Bits RE547 Series Rock Drill
Bits
Describtion
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.

Applications
• Underground mining
• Quarry benching operations
• Water well drilling
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.
Competitive Advantage
Main hammer components manufactured from high grade steel and
processed using state-of-the-art CNC machinery and heat treatment
