Drilling Tools Core Barrel Bucket With B47K22H Teeth For Hard Rock Construction
Application:
1.Fractured rocks and hard rocks that the hardness is less than 80 MPa, relatively hard bedrock formations, large boulder layers and hard permafrost layers.
2.Apply to obvious layered medium weathered sandstone (high probability of coring) hard rock cutting.
3.In higher compactness of soil or part of the soft rock strata,slippage due to selection of friction Kelly bar,can try to use core barrel.
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.Barrel adopts spiral wear resistant strips ,anti-attrition,prolong service life.
5.Adopts wear resistant block between teeth holders due to protect teeth holder and stiffening ring from serious wearing .
