Low Tooth Loss Rate Anchor Drill Bit Using Advanced Alloy Tooth
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.
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
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
