Drill Bits

Brief Introduction:

Sinorock® self drilling rock anchor system can overcome the problems of difficult to drill holes in loose and broken soil. It can realize the stabilization of side slope. Drill bit is a part of Sinorock® self drilling rock anchor system,which consists of rock anchor, plate, nut, coupling, drill bit and centralizer.

Application:

1. Management of geological disasters.
2. Reinforcement of underwater projects.
3. Supporting of underwater projects.

Feature:

1. Various processing methods are available. Steel drill bit is produced by casting or machining methods, and tungsten carbide drill bit is produced by machining processing method.
2. Properties of the drill bits are designed according to the requirements of construction. Cutting part and button of the drill bits are ensured specific hardness and the drill bit body needs to have high toughness so that drill bit will have good performance in the construction.
3. Drill bits are designed according to the standard of rock drilling tools.
4. Abundant types of drill bits to adapt to different layers according to different rock conditions, different shapes of cutting parts can be designed. Base on large amount of testing and data validation, Sinorock works out a set of standard for the choice of drill bits, which can provide efficient and accurate construction guidance for clients.
5. Cross-sectional area of the drainage hole should be not less than the cross-sectional area of the inner diameter of self drilling rock anchor.
