Top hammer shank adaptors, the role of which in rock drilling is to directly bear the impact energy and torque of the rock drill, and is used to transfer the energy from drill rig to drill rod. One end of the shank adaptor is connected to drill rig, and another end is connected to drill rod, so that the energy of drill rig can be transmitted to drill bit, and finally achieve the purpose of drilling.
Retract drill bit china are mainly used in loose rock mass with relatively broken rock. The retrac skirt design can assist in retrieving the drill tool, reduce the phenomenon of bit stuck and buried, and help improve the straightness of the borehole.
As a China retrac button bit supplier, we can provide you with high-quality button bit includes retrac rock drill bits, such as R25 retract button bit, R28 retract button bit, R32 retrac button bit, R35 retrac button bit, R38 retrac button bit, t38 button bit, T45 retract drill bit, T51 retract drill bit, GT60 retract button bit, ST58 retrac button bit, ST68 retrac button bit, SR35 retrac drill bit and other types of rock drill bit.
Several customers have been tried for this by drilling 'holes' on the new iPhone 7 after watching this prank video on YouTube, suggesting that the process may help them bring back their missing 3.5mm headphone jack.
In quarry and aggregate industries, the application of top-hammer rock drilling rigs can improve operational efficiency, safety and stability, as well as adapt to the increasingly stringent emission reduction and environmental protection standards.
With the attention and investment of the infrastructure industry at home and abroad, in many construction industries with high construction difficulty and high risk, the mechanized drilling and blasting construction of rock drilling rigs have gradually replaced the pneumatic drilling and blasting construction with more personnel, high labor intensity, large safety risk, and low efficiency.
Reaming bit, also known as pilot reamer bit, is a hole opener that drills a pilot hole to a certain depth and then reams the hole to a larger diameter. It is mainly used for center hole reaming in long hole drilling. Threaded reaming bits are divided into integral reaming bit (dome type, pilot type) and split-type reaming bit. Our reaming button bits are mainly dome reaming bits and pilot reaming bits, such as R25 reaming bit, R28 reaming bit, reaming bit R32, R35 reaming bit, R38 reaming bit, T38 reaming bit, T45 reaming bit, T51 reaming bit, ST58 reaming bit, ST68 reaming bit, SR35 reaming bit.
MF rod, also known as speed drill rod, has a male thread at one end and a female thread at the other end. It can directly connect to the shank adapter without the aid of a coupling sleeve, which eliminates the defect that the equal diameter thread connection is prone to vibration. The quick-change properties of male/female rods improve the overall drilling efficiency.
Litian shank adapters select high-quality alloy structural steel as raw materials, adopt advanced thread manufacturing technology and surface treatment technology, and are manufactured according to precise tolerances, which can minimize the loss of impact energy during the transmission process.
Our shank adapters are applicable to various brands of rock drills, such as Sand vik (Tomrock) rock drills: HL300, HD400, HL500, HL600, HL700, HL850, HL1000, HL1500, HLX5, RD520 series, etc.
Raise boring cutter (RBM cutter) is a tungsten carbide insert roller cutter mounted on the reaming head of raise boring machine (RBR, raise borer), which is an excavation tool for breaking rocks. As the most important raiseboring drilling tools, the raise boring cutters are mainly used in the construction of vertical shafts, inclined shafts, surge shafts, ventilation shafts, and escape shafts, and can be widely applied in underground engineering construction fields such as mine, hydropower, transportation and so on.
The construction of every tunnel excavation and underground project requires the coordinated operation of various types of equipment. Rock drilling tools & tunneling tools used in underground tunnel construction are crucial instruments for penetrating and breaking through rock layers. Choosing the right rock tools not only withstands the harsh conditions and high pressure encountered during tunnel construction but also significantly enhances the speed and safety of underground tunnel construction. This, in turn, shortens project timelines and improves cost-effectiveness.
Litian shank adapters use high-quality alloy structural steel, and adopt a complete set of mature technology such as advanced surface treatment technology, smelting technology, and mechanical processing technology, which can greatly reduce the loss of energy in transmission and make the rock drilling speed fast.
