Drilling cross cutters core barrels for drilling gravel rock foundation rig
Advantages
1. Cross cutter core barrel is mainly used to break rock cores which remain in the borehole after using a core barrel, also suitable for drilling hard, jointed rock(<100Mpa) and for penetrating through layers containing boulders.
2. For the rock column that fails to take the core, this drill can effectively improve the drilling and slag carrying capacity and improve the drilling efficiency.
Customizable Items
1. Cutting DIA. Custom : design various cutting diameter based on demand, like φ850,φ1150 etc.
2. Shell HIT. Custom : design as demand, prolong or shorten, increase of efficiency by drilling more.
3. Key Component Reinforce Custom : strengthen the key component to extend life cycle;
4. Kelly Box Custom: custom Kelly box size based on the Kelly bar, like 130*130, 150*150,200*200 etc;
5. Teeth No. Custom : encrypt the drilling teeth based on demand etc;
