Rock drill bit

Alias:Cylindrical drill bit, also known as ball tooth drill

The combination of rock drilling bit and hydraulic rock drilling rig is the best matching for modern rock drilling technology.

The most commonly used models of stud drills are [32 stud drills, 40 stud drills], taper connection drills 7°, 11°, 12°.

Product Description

Advantages of cylindrical drill bits:

It has the characteristics of long service life, accurate positioning, coarse cuttings, low dust, durability and no need for grinding. Compared with traditional chip drill bits, the drilling speed is fast, and the ball-tooth drill bit has a long passivation life cycle, and its non-grinding life is about It is 5-6 times of the grinding life of the same diameter blade head, which is beneficial to save auxiliary man-hours, reduce the physical labor of workers and speed up the project.
The hardest part of the column tooth bit is the upper column head, which is made of wear-resistant alloy, and the lower shank is cast steel. The threaded buttons below have inner threaded buttons and some without threaded buttons. When ordering, the type of thread should be determined according to the thread condition of the customer's drill pipe.

1. DTH cylindrical bit
DTH stud bit is a kind of bit used with DTH impactor. It is used for drilling operation through spline and impactor. It is widely used in open pit mining, quarry, hydropower engineering, and water well drilling Support of digging column, etc. It is divided into: low pressure DTH cylindrical bit, medium and high air pressure DTH cylindrical bit. The DTH cylindrical bit is used in conjunction with the DTH impactor, which has the advantages of straight drilling, fast speed, Features of deep drilling.

2. Taper coupling cylindrical drill bit
The taper connection column tooth bit is mainly used with the pneumatic rock drill and the taper rod. It is connected with the drill rod through the taper to carry out the drilling operation. excavation and other fields.

3. Threaded stud bit
Threaded connection column teeth are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (pneumatic drill rods). ￠32-￠203mm.
Advantages of rock drill bits:

Long service life, accurate positioning, coarse cuttings, low dust, durable without grinding, etc. , Compared with the traditional chip drill, the drilling speed is fast, the passivation service cycle of the ball tooth drill is long, and its non-grinding life is about 5-6 times of the grinding life of the same diameter blade bit, which is conducive to saving auxiliary man-hours. , reduce the manual labor of workers and speed up the construction speed.
The hardest part of the column tooth bit is the upper column head, which is made of wear-resistant alloy, and the lower shank is cast steel. The threaded buttons below have inner threaded buttons and some without threaded buttons. When ordering, the type of thread should be determined according to the thread condition of the customer's drill pipe.

Cylinder bits are mainly divided into the following categories: Class:
1. DTH cylindrical bit
DTH stud bit is a kind of bit used in conjunction with DTH impactor. It is used for drilling operations through spline and impactor, and is widely used in open-pit mining. , quarry, hydropower engineering, support of side column for drilling and excavation of water wells, etc. It is divided into: low pressure DTH stud bit, medium and high wind pressure DTH stud bit. DTH stud bit and DTH impact It has the characteristics of straight drilling, high speed and deep drilling.

2. Taper Coupling Cylindrical Bits
The taper connection column tooth bit is mainly used with the pneumatic rock drill and the taper rod. It is connected with the drill rod through the taper to carry out the drilling operation. excavation and other fields.

3. Threaded stud bit
Threaded connection column teeth are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (pneumatic drill rods). ￠32-￠203mm.
The rock drilling bit products produced by our company are widely used in various regions at home and abroad. The main domestic application areas are: China Coal Group, Longmei Group, Shenmei Group, Fengfeng Coal Industry, Kailuan Coal Industry, Lu'an Coal Industry , Yangmei Group, Jinmei Group, Xishan Coal and Electricity, Fenxi Coal Industry, Datun Coal Industry, Xinji Energy, etc.; the main use areas in foreign countries: Russia, Australia, Southeast Asia and Northern Europe.
