Feature
1. Cutting ring with rock drilling bits and releases the internal stress of rock；
2. Rock drilling bits perform stage breaking and drilling;
3. Small barrel facilitates the coring operation; large barrel performs stage breaking;
4. Applicable layers: backfill layer, medium weathered rock, bedrock;
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;
Application
1. Core barrel with bullet teeth is used for cutting an annular ring in rock or concrete(also reinforced concrete).
2. Core barrel with roller bits is used in very strong rock formations(compressive strength >100Mpa).
3. 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.
