When tool manufacturers are creating tools sometimes they are doing it out of pure Tungsten rods or other raw materials. These turnings that are created have value and can be shipped to RRCarbide.com for a scrap value and rebate. These turnings or chips could have an oil residue that would lessen the value of the scrap. Anytime that tungsten turnings are mixed with other turnings you will always receive a lower price due to the sorting.
