The straight-line series drill bits have simple manufacturing process, convenient regrinding, reliable operation, and strong adaptability to rock mass properties. It is often used with light internal combustion electric pneumatic and hydraulic rock drills to drill holes below the diameter in various types of rocks.
Due to its low price and other characteristics, it is still the main type of drill bit used in small and medium diameter rock hole drilling projects in my country's mining industry.
Our company's straight-shaped bit has the following significant advantages
. Complete range of specifications
From diameter to diameter, diameter to diameter, diameter to diameter, etc.
. Reasonable material selection and excellent manufacturing
Strict quality control, not only focusing on the intrinsic quality of the product, but also very fine surface treatment.
. Scientific design, beautiful appearance and unique packaging.
. Reasonable product structure
High, medium and low-end products to meet the needs of different customers. The alloy classification is suitable for rocks with different hardness coefficients.
. Be brave in innovation and continue to improve.
. The sales channels are smooth and the service network is sound.
Cross-type drill bit refers to a drill bit with four pieces of carbide embedded in the head of the drill bit. The product is made of high-quality steel and processed by a special heat treatment process. It has a variety of different design models to adapt to different operating environments. Tapered hole drill bits with various taper connections are a supporting product for the tapered rod (finished drill bit). They are connected to the tapered drill bit through the tapered hole. They are currently the most commonly used drill bit type in China. The advantage of the cross-shaped bit is that it is suitable for drilling fractured rock formations and highly abrasive rock formations under the condition of a rock drill with a large impact power, and has strong resistance to radial abrasion. Corresponding to different rock types, different brands and models of alloys must be selected.
The cross drill bit series is the main variety among the international flake series drill bits. The diameter of the drill bit is within the range, and it has strong adaptability to rock drilling conditions and is almost not limited by the rock drilling machine model and rock mass performance. In mining projects in many countries, such as Sweden and Canada, cross and ball tooth drill bits are commonly used instead of straight drill bits.
On the basis of comprehensively absorbing foreign experience in the cross drill bit process, combined with the current status of my country's materials and drill tool manufacturing technology, our company has adopted a brand-new approach in four aspects, including geometric structure and parametric material manufacturing technology. Design, reaching the highest domestic level.

The ball tooth series drill bits
have a long passivation life, and their non-grinding life is about
times the grinding life of the blade head of the same diameter. It is beneficial to save auxiliary working hours, reduce workers' physical labor and speed up the project. Therefore, taper connection and threaded connection ball bits of different diameters are widely used in various types of hard and brittle rocks to cooperate with drilling rigs for rock drilling. Swedish engineering and technical personnel believe that the combination of
ball-tooth bit
and hydraulic rock drilling rig is the best match for modern rock drilling technology.
In recent years, ball tooth series bits have developed rapidly at home and abroad. It is realized with the goal of quickly drilling holes with hydraulic rock drills to save auxiliary drilling hours and increase industrial drilling speed.
Compared with traditional blade drill bits, cylindrical tooth drill bits have the characteristics of longer grinding cycle and faster drilling speed. They can be divided into the following categories
Hole cylindrical tooth drill bits
Down the hole The column-tooth bit is a drill bit used in conjunction with a down-the-hole impactor. It cooperates with the impactor through splines to perform drilling operations. It is widely used in open-pit mining, quarries, hydropower projects, water well drilling, and drilling. The support of the excavation side pillars is divided into low pressure down-the-hole column bits, medium and high air pressure down-the-hole column bits. The hole column drill is used in conjunction with the down-the-hole impactor. It has the characteristics of straight drilling, fast speed, and high drilling efficiency. The characteristics of deep holes have been widely used in recent years
Threaded connection column teeth
Threaded connection column teeth are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (pneumatic drill bits) A drill bit used in conjunction with the drill rod). It uses different forms of threads to cooperate with the drill rod to perform drilling operations. The diameter of the drill bit ranges from ￠￠. It is mainly used in the mining of underground mines, the mining of open-pit mines, and the opening of blast furnaces in steel plants. Fast and convenient grinding
High-speed connection cylindrical bit
Taper connection cylindrical bit is mainly a drill bit used in conjunction with the pneumatic rock drill and the taper rod. It is connected with the drill rod through the taper. Drilling operations are mainly used in the excavation of tunnels supported by secondary crushing anchors in mines.
