DTH Drilling A down-the-hole drill, usually called DTH is mainly a pneumatic powered rock or ground drill, in which the percussive hammer is located directly behind the drill bit, so the percussion mechanism follows the bit down into the drill hole. The drill pipes transmit the necessary feed force and rotation to the DTH hammer […]

Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground.
It was only when down the hole hammers came along that many of the problems associated with the other systems were overcome – with the DTH system and dth drilling tools, the energy source is constantly behind the drill bit with copious amounts of air passed through the drill string to operate the DTH Hammer which is then used to efficiently
DTH Hammer Bits. We have a large inventory of hammer bits ranging from 4" to 17-1/2" in IR, QL, and Mission shanks. Economize the insert cost even more by reclaiming the used diamonds (if in good shape) and have them reinserted in to a new bit body. Please contact us for additional details. 23" Bit with 4" Hammer and Bit . 24" SD12 Bit
Kefid · DTH hammer means that rotation head vibration is appreciably less than that created by the rotary method. Because minimal thrust is applied to the DTH hammer, it deviates from its course very little and drills a straighter hole than the rotary bit. DTH offers longer bit life and faster penetration rates in medium to hard rock at any depth.

Alibaba.com offers 396 used dth hammer bit products. About 64% of these are mining machinery parts, 7% are drill bit. A wide variety of used dth hammer bit options are available to you, such as carbon steel, carbide, and high manganese steel.
The air exhaust system is controlled by the percussion bit and the air passages to the surface. As with any non-electrical motor, any exhaust restriction will reduce the motors power. In the case of a DTH Hammers air exhausting from the hammer is also used to carry the rock cuttings to the surface.
Liming · Brazing is widely used in the tool industry to fasten "hard metal" (carbide, ceramics, cermet, and similar) tips to tools such as saw blades. "Pretinning" is often done: the braze alloy is melted onto the hard metal tip, which is placed next to the steel and remelted.Basics · Common techniques · Heating methods · Safety · Filler metals

DTH Bits. The drill bit is the cutting element of any DTH drilling system and a hammer is only as good as the bit it uses. The down-the-hole bit (DTH) is subject to severe stress from the striking piston as well as from the abrasive cuttings passing around the bit at high velocity.
In horizontal applications, an auger is also fitted onto the backend of the hammer to promote more efficient cleaning of the hole during drilling. The system’s center bit is connected directly to a DTH hammer and the ring bit is attached directly to the casing being installed.
The Down-The-Hole hammer is designed to increase efficiency in drilling as well as conventional drilling. The presented series can be used for multiple purposes such as the geotechnical, mining, quarrying, geothermal, mineral, underground, and other exploration drilling.. Pay attention that the Down the Hole (DTH) hammer is designed for drilling multi-size holes whatever the rock type’s demand.
