Unground carbide blank rods are raw sintered tungsten carbide bars without precision outer diameter grinding, also known as sintered carbide blanks. They come with natural sintered surface and basic dimensional tolerance, serving as the base raw material for further grinding, polishing and cutting tool manufacturing.
Compared with ground H6/H7/H8 carbide rods, unground carbide blanks feature lower production cost and shorter delivery lead time. Customers can conduct secondary outer circle grinding, length cutting, chamfering and forming according to their own tool processing requirements.
