Abstract: The present invention is directed to a cutting tip device, and method of using the device, for removing the build-up of particulate from an internal surface of a storage bin, such as a coal bunker or a grain silo. The cutting tip is attached to a source of compressed gas by a hose, and includes at least one internal gas passageway through which the compressed gas is forced. The compressed gas is at a predetermined minimum pressure and flow rate sufficient to cause the cutting tip to gyrate in an erratic fashion about the hose, and to strike the build-up with sufficient force to remove the particulate from the interior of the storage bin. By lowering a hose having the cutting tip attached to it into a storage bin and forcing compressed gas through the hose and cutting tip, the interior of the storage bin is cleared of its build-up.
