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> 100 Mpa).
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(< 1 00Mpa) and for penetrating through layers containing boulders.
Advantages
High quality raw materials and high steel strength.
Simple operation.
High wear resistance.
High drilling efficiency.
High hardness.
Good roundness of the cylinder.
Long using life.
