Friction welding drill rods Drilling Rig Tools Heat Treated Carbon
Alloy Steel
1. Our series anchor drilling tools include all kinds of drill
rods,casing,eccentric drill tool,concentric drilling tools and
hammers.These products can meet various construction requirements
of clients.
2. Anchor drill rod is mainly suitable for DTH hammer.It features
large rigidity,good tightness,low torque and small resistance.The
drill rods have many specifications,such as 73mm and 89mm.
3. Among these tools,eccentric drill tools and casing are usually
matched with DTH hammer.The hammer has features of simple
structure,reliable operation,good performance and convenient
maintenance,it can match all kinds f anchor drill rods and casing.
4. These products are reliable,they have stable performance and can
fulfill various drilling construction,such as DTH hammer,drilling
with casing and RC drilling,the products can suit the drilling in
crushed and complex formations.
5. The operations are very simple,remote operation can be
realized,these products can effectively reduce labor intensity and
auxiliary time.
Drilling rod is used for percussion-rotary drilling with
down-the-hole (DTH) hammer (including hydro-hammer and
pneumatic-hammer). High rigidity, good sealing ability and uniform
outer diameter are structure feature of external flush rod,
therefore, it has advantages of low rotary torque and resistance.
Main dimensions as follows: Diameter(mm)×length(m)
Φ50×1.0, Φ50×1.5, Φ73×1.0, Φ73×1.5, Φ89×1.0, Φ89×1.5, Φ114×1.0,
Φ114×1.5
The material has been specially heat treated,it has advanced leak
proof structure,it is made of carbon alloy steel.
Special specifications can be manufactured according to customer's
requirements

High rigidity, good sealing ability and uniform outer diameter are
structure feature of external flush rod, therefore, it has
advantages of low rotary torque and resistance.
The drill rod body and joint are welded through friction welding
technique,the welding strength and straightnee of the rod.
The drilling rod is applicable to many fields,such as geological
disaster prevention and control,urban high building foundation
treatment and tunnel collapse.
