Elephant rock hole opener suitable for all types of non-excavation drill and can be extended for a variety of rock formations hole construction.

Features of the rock reamer with roller cones:

1. The roller cones has suitable tilting angle and inlayed strengthened alloy on the cone palm which prevent premature wear of the palm;

2. With the cone anti-dropout technology, to maximally prevent downhole accidents caused by cone body dropout after damages of bearing;

3. Timely cooling in the welding process prevent the seal damage caused by the overheat of the roller cone;

4. Selection of the most suitable tooth based on the different formations, thus to promote the construction efficiency;

5. For large-scale reaming, weight reduction design effectively reduces the weight, linear change tendency of the pipeline trajectory to reduce the blocking when the reaming and dragging are conducted.

Features of the rock reamer with replaceable roller cutters：

1. The roller cutter wheel body is cold mounted with tungsten carbide, providing good rock breaking effect; bearings featuring large diameter enables great impact resistance;

2. The mainly body made of great solderability alloy steel, quenched and tempered has great tensile resistance and can satisfy the tensile demand of large HDD rigs;

3. Reliable connection between the wheel body and the main body can facilitate on-site replacement of the wheel, no need of large professional hydraulic machines;

4. Suitable shapes of the roller cutters can be installed at the customer's specific rock formations, enhancing working efficiency and lengthening working life.
