Top Hammer Drilling Tools
Top hammer rock drilling toolsare kinds of rock tools widely used in top rock drillingapplications, such as open-pit mining, quarrying, underground mining, rock bolting, tunneling, and production drilling. The top hammer rods, top hammer tools, top hammer bitsinclude four parts: Drill bit, Drill rod, Shank Adapter, and Coupling Sleeve.

Top Hammer Rock Drilling Tools From Litian
Litian is a professional manufacturer of high-quality top hammer rock drill tools with optimal drilling hole quality, high stability, and long service life. The top hammer rock tool servicesare designed and produced to transmit high-frequency impact energy into the rock and minimize energy loss to improve the rock breaking rate, penetration rate, and productivity.
In terms of product consultation and rock tool services, we can select the most suitable rock drill tools and drilling construction schemes according to the user's construction conditions, rock type, mineral conditions and the drilling equipment, so as to help users improve drilling efficiency, reduce drilling costs, and achieve better comprehensive benefits and higher labor productivity.
What are the reasons that affect the service life of top hammer rock drilling tools?
①Raw material and technology
High-quality raw materials and advanced processing technology can guarantee the overall drilling quality of the rock drill tools from the source and prolong its service life. Choose qualified rock drilling toolsand rock drill accessoriesfrom large standardized manufacturers.
② Whether the rock drill tools assembly are concentric
When drilling rock, the shank adapter, the drill rod, and the couplings should be in concentricity. The misalignment of the three will cause bending and deformation of the top hammer drill tools, resulting in stress, resulting in the joint can not cooperate effectively, and causing looseness.
③ Improper use of rock drill tools
When connecting the top hammer rock drill tools, it is easy to damage the rock drill tools if there are mud and sand on the thread, or if there is no lubricating oil at the threaded connection. The combination using of the used drilling rig tool and the new drilling rig tool will shorten the service life of the drilling tool. In addition, the empty beating of rock drill tools should be avoided as far as possible.
④ Propulsion pressure and impact pressure
The propulsion pressure and impact pressure should be set within the rated pressure range.
If the propulsion pressure is too low, it will reduce the drilling penetration efficiency, cause the drilling tool assembly to loosen, and the transmitted energy will be lost, which will cause great stress and cause the instantaneous contact and separation of the contact and joint end faces. If the pressure is too high, the rotation speed of the drill bit is low, there is a danger of sticking, and the bending stress of the drill rod increases.
Improper adjustment of the impact pressure will directly affect the rotation speed and drilling efficiency, and will also affect the life of the drilling tool.
⑤ Rotation speed and rotation pressure.
The rotation speed should match the drill bit diameter and the impact frequency of the top hammer drill tool. The cemented carbide of the drill bit has to be rotated at an appropriate angle after each impact, so that new rocks are broken each time.
The normal rotary pressure can provide proper anti-sticking protection for the drill rod. The increment of rotary pressure is the key factor to maintain the tightness of the rock drill tools. if the tightness is not enough, it often causes heating of the joint, peeling off of the thread surface, early wear and even fracture of the thread.
