Product Description

Product Description

The column tooth bit, also known as the ball tooth bit, combined with the hydraulic rock drilling rig is the best match for the modern rock drilling technology.

The most commonly used models of cylindrical teeth are [32-column drill bits, 40-column teeth drill bits].
Taper connection drill bit Cylinder bit 7°, 11°, 12°

The advantages of the column tooth bit: long service life, accurate positioning, coarse cuttings, low dust, durability and no need for grinding, etc. Compared with the traditional chip bit, the drilling speed is fast, and the ball tooth bit is passivated. Long service life , its non-grinding life is about 5-6 times of the grinding life of the same diameter blade head bit, which is conducive to saving auxiliary man-hours, reducing the physical labor of workers and speeding up the project speed.
The hardest part of the stud bit is the upper stud, 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 teeth are mainly divided into the following categories:

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 It is divided into: low pressure DTH cylindrical bit, medium and high wind 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 column teeth are mainly used with hydraulic rock drills (or pneumatic rock drills) and hydraulic drill rods (pneumatic drill rods). ¢32-¢203mm.
