Product Details

Low Tooth Loss Rate Anchor Drill Bit Using Advanced Alloy Tooth Assembly Process

 

 

Description:

 

Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Bits are held in a tool called drill, which rotates them and provides torque and axial force to create the hole. Sinorock drill bit is suitable for various ground condition. It is especially efficient and fast when drilling in hard and medium-hard rock.

Advantages

1, The hard alloy tooth material adopts high wear-resisting formula, and the breaking rate is less than 2%.

 

Fast, single-step anchoring system with simple equipment able to work with standard track drill (top hammer) or hand-held drilling equipment, eliminating the need for larger casing rigs.

Installation with simultaneous drilling and grouting possible, and post grouting system is simple.

Continuously drilling and grouting under high pressure causes the grout to permeate into looser soils and creates a bulb-effect for increased bond capacity.

The self‐drilling hollow bar anchor system is comprised of a hollow threaded bar attached with a drill bit that performs drilling, the hollow bar allows air and water to freely pass through the bar during drilling to remove debris, after drilling at the required depth is completed, grout fills the hollow bar through the pressure for their requirement and completely covers the entire bolt
Coupler: The couplers can be used to join hollow bars and extend the bolt length, it means the anchor can be elongated with the couplers
Plate and Nut: The plate and nut are installed according to their design requirement Drill Bit: The drill bit would be selected at the choice of ground condition
