H.B. Carbide, a manufacturer and global supplier of carbide blanks and pre-forms, offers its HB-3 grade, a submicron carbide specially designed for use in cutting tools for highly abrasive machining applications and wear components.
With a 6% cobalt binder and 93 HRA hardness, grade HB-3 is well-suited for wear parts and cutting tools being used in non-ferrous, machining applications. It offers a homogenous microstructure and uniform grain distribution that makes this grade an ideal choice for cutting tools used for machining in ISO K20 applications; specifically aluminum alloys, graphite, fiber-reinforced materials and composites. It can be applied for use in drills and reamers, form tools, end mills, and other solid carbide cutters.
The high hardness and high wear resistance of HB-3 can also provide excellent performance in wear parts such as drawing tools and industrial-grade nozzles.
Importantly, with a 6% cobalt content, HB-3 has proven to consistently offer superior coating adhesion. This makes it an excellent substrate for toolmakers who will be applying diamond coating to their tools, especially those used for composite routing and drilling.
Says Jon Wyniemko, Director of Global Sales at H.B. Carbide, “In addition to HB-3 carbide being an outstanding substrate selection across a variety of high-wear-resistant material applications, the consistency of the H.B. Carbide manufacturing process ensures reliable performance and prompt lead times across a variety of blank configurations.”
H.B. Carbide company manufactures custom, standard, and altered blanks and pre-forms in a comprehensive selection of tungsten carbide grades. Vertically integrated, it manages the entire process from powder production through the delivery of high-performance, reliable near-net shaped blanks that address specialized customer application challenges across diverse industries. At H.B. Carbide, our results speak for themselves.
