Product Description


ISO9001 BQ BWL Drilling rods for Core Drilling Rig , Φ55.6 x 46 x 4.8 mm




Wireline drill tools can lift drill core from drill rods without picking up it. All the tools include parts of the drill tools, overshot assembly, wireline winch, drill rod, lifting appliance, holder and so on. Their advantages are higher penetration, higher core recovery ratio, longer bit life and lower labor intensity, and the advantages get more clear with the increasing of hole depth.

Q series wireline core drill rods are made of strong and ductile geological steel pipes which are entire-length thermal processed. Rod threads are formed using former cutters and specially hardened so that their accuracy and mechanism reach advanced world standard.                     
Now we have large quantity drill rods in store.

----- ISO9001: 9002 certificated
----- 50 years manufacturing experience
----- Super antiwear characteristic
----- Super long lifetime
----- Solid quality
Raw Materials:
ROSCHEN choose the best steel tubes in the market to manufacture our drill rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.
