H.B. Carbide is an industry leader in top-quality tungsten carbide rod, blanks and preforms. We use high-quality materials and high-tech computer-controlled vacuum furnaces to produce a variety of cemented carbide preforms for many specialized applications. These custom and altered standard carbide blanks provide consistency, reliability and advanced capabilities for your most demanding applications.
Our expertise enables us to produce carbide preforms in just about any shape you require in a wide range of hardness and density. These preforms, which are near the final cutting tool shape, allow for major portions of carbide to be removed while still in the green state. Compared to the hard state, drilling of coolant holes, pre-fluting, and grinding different diameters are accomplished in a fraction of the time. We leave a minimal amount of grind stock, which saves you grinding wheel life and increases machine capacity.
