Strong Compatibility Round Shank Chisel Concrete Core Barrel
Application:
1.When rotating, the drill core of the core rock drill has several different cutting angles that are matched with each other, and it is repeatedly broken and knocked at the position of the ring groove in the hole.
2.Fractured rocks and hard rocks that the hardness is less than 80 MPa.
Feature
1.Cutting ring with rock drilling bits and releases the internal stress of rock;
2.Heightening design,high construction efficiency ,efficiency reduce construction cost.
3.Adopts wear resistant block between teeth holders due to protect teeth holder and stiffening ring from serious wearing .
