Industrial grade Rotating Scratchers consist of a split collar which houses double coiled external and internal bristles. These Rotating Scratchers have the external bristle system inclined 200 and shielded by slight elevations in the collar. These Rotating Scratchers serve to remove mill scale and other foreign matter from the casing with the help of internal bristles. These Industrial grade Rotating Scratchers reduce the abrasive action when casing is run into the hole and improve the bounding of cement to the casing.
