HB-2 is a medium grain tungsten carbide grade developed for excellent wear resistance and abrasion durability. As a general-purpose carbide, HB-2 is ideal for finishing and semi-finishing cutting tools, offering a reliable balance of toughness and strength. It’s also well-suited for diamond coating, making it a great choice for specialized machining and wear part applications.
