The tungsten carbide rods(also named cemented carbide rods) are used in making high-quality carbide cutting tools for the machining of heat-resistant alloys and Ti alloy, such as end mill, drill, and reamer. They can withstand high compressive stresses imposed during cutting, as well as having good wear and oxidation resistance at the high temperatures reached.
Cemented carbide rods/round bars with coolant holes for milling have various dimensions, blanks or finished, and many different grades with different applications for customer selections.
