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
