The rock drill bit is connected with the drill rod, through the drive of the rock drill to achieve the purpose of cutting rock parts, the whole system to bear the greatest impact and wear parts. There are different types of rock drill bits, such as chip bits, button bits... Kelleg offers a wide range of rock drill bits, including top hammer bits and DTH drill bits.
Top hammer bit type
1. chisel bit: suitable for light rock drills to drill rock formations with low hardness.
2. Cross bit and X bit: suitable for drilling cracked rock formations and highly abrasive rock formations under the condition of rock drills with large impact power, and have strong radial abrasion resistance.
3. Button bit: Under the condition of a rock drill with a large impact power, it is more suitable than a flaky insert drill bit, has a higher rock drilling speed and service life, and the drilled hole shape is relatively round.
4. Diameter of drill bit:
chisel bits: 32mm-42mm
cross bits: 34mm-65mm
X bits: 55mm-65mm
button bits: 38mm-150mm
DTH drill bit type
1. Including low-pressure DTH drill bits, medium and high-pressure DTH drill bits (high-efficiency and energy-saving types)
2. Nominal diameter:
low-pressure DTH drill bits: 70mm- 250mm
medium and high-pressure DTH drill bits: 90mm-508mm

The drill rod is the part that links the drill bit and the shank adapter in the rock drill and undertakes the task of transmitting the impact energy to the drill bit, the rotational torque, and the flushing medium. In actual use, the force conditions of the drill rod are harsh, and it is easy to consume a large number of wearing parts.
Product Category
Drill rods include tapered drill rods and threaded extension rods according to their connection methods.
Tapered drill rod: It is suitable for drilling shallow holes, the tail is connected with the rock drill using the shank adapter, and the tapered part of the head is connected with the drill bit.
Threaded extension rods: It is more suitable for drilling deep holes. It can use a sleeve with female threads to connect two drill rods with male threads. With the deepening of the hole depth, multiple drill rods can be connected. It is very convenient to remove the rod from the connection after chiseling.
Except by connection type, drill rods include light drill rods and heavy drill rods.
Light drill rods include tapered drill rods, shank rods, and integral drill rods.
Heavy drill rods mainly include drill rods used for drifting and tunneling rigs, benching drilling rigs, and Open-cutting drilling rigs.
Length
Light drill rods: 300mm-6000mm(without shank, the conventional length of the shank is 108mm).
Heavy drill rods: 600mm-2000mm(Drill rods less than five meters are available).

As a modern supporting rock drilling tool, the shank adapter is produced with the development of drilling technology and rock drilling conditions. In terms of rock drilling technology, when developing from shallow hole drilling to medium and deep hole drilling, due to the limitation of the working section, to obtain deeper rock holes, it is necessary to use coupling sleeves on the same axis of the drill rod. Connect multiple drill rods for drilling. The shank rod used in this rock drilling process is the prototype of the development of the shank adapter.
With the development of rock drilling equipment, the matching parts of the shank rod as a matching drill tool and the rock drill are more complicated, and the technical requirements for connection and cooperation are becoming more and more strict. To adapt to the changes, shank adapters of various structures have been produced.
Shank adapter classification
Common shank adapters are mainly divided into three categories: flange-type shank adapters, lug-type shank adapters, and spline adapters. The cross-section of the flange-type shank adapter is hexagonal, 22mm or 25mm for the inscribed circle diameter and 108mm or 159mm for length. It is manufactured by the forging process and is used for light rock drills. The lug-type shank adapter is used for inner-rotating medium-sized guide-type rock drills, and the diameter of the drill rod is 25mm or 32mm. The spline adapter is often used for heavy-duty guide-type external rotating rock drills with large torque, and the diameter of the drill rod is more than 38mm. It is often manufactured by a mechanical process.
Product Parameters
Shank adapter for pneumatic guide rock drill: It is suitable for small rock drills and can be operated manually.
Shank adapter for Atlas Copco rock drill: It is suitable for the Atlas Copco rock drill, one of the most commonly used rock drills.
Shank adapter for Sandvik Tamrock rock drill: It is suitable for the Sandvik Tamrock rock drill, one of the most commonly used rock drills.
Thread size: R28, R32, R35, R38, T38, T45, T51.

The coupling sleeve is an indispensable part of rock drilling tools for rock drilling. During the drilling process, the coupling sleeve is at the joint part of the matching drill, which bears the corrosion effect of stress such as axial tension and compression, bending and torsion, contact, and friction.
The coupling sleeve used for threaded connection rock drill tools is to use its thread to connect two or more drill rods or shank rods on the same axis, transfer the impact function of the rock drill, and achieve the purpose of drilling rock holes, which is the same as the drill rod. It acts as a stress wave propagation carrier.
Coupling sleeve classification
1. Classification by the geometric structure
There are straight-through coupling sleeves, reducing coupling sleeves, and middle-stop-type coupling sleeves.
2. Classification by thread structure
There are coupling sleeves such as wave thread, compound thread, trapezoidal thread, etc.
Product Parameters
Coupling sleeve type: full bridge coupling sleeve and reducing coupling sleeve
Thread size: R32, R38, T38, T45, T51.

The split set is widely used in coal mining. It is a new type of full-length anchor, and the three-dimensional part is a high-strength steel rod with a longitudinal slit. When installed in a hole slightly smaller than the pipe diameter, it can immediately apply radial pressure on the hole wall and the friction force to prevent the slide of the surrounding rock, plus the supporting force of the bolt tray, so that the surrounding rock is in a three-way stress state, and the rock stability is realized.
Advantage:
1. Good support effect.
2. Low support cost.
3. Low labor intensity.
Product parameters
Split set is mainly composed of anchor rod and tray.
The anchor rod has two wall thicknesses, 2.5mm and 3.0mm.
There are two types of trays, one with earhook and one without.
Common specifications: �?30, �?35, �?39, �?43, �?46.
