High grade tungsten carbide inserts DTH Tools RC-E545 Bits and Hammers
For Mining Well Drilling
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.
Color: Green,Blue or Based on Customer requirements
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.
dth rock drill bits have four kinds of button type
Spherical button : good wearing resistance, suited to hard ground, abrasive to very abrasive.
Parabolic button : fast penetration,suited to medium to hard rock,suitable for the mildly abrasive ground.
Conical button : fast penetration, suited for smaller diameter bits, suited for all non-abrasive ground types.
Ballistic button : fast penetration,suited to soft rock, suitable for non abrasive ground
Applications of DTH Bit
• Underground mining
• Tunneling
• Quarry benching operations
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
