Carbide Grade Selection

Grade HB-2

A Medium Grade Carbide

Reliable, All-Purpose Grade with Strong Wear Resistance

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.

Benefits

Excellent Wear Resistance

  • Withstands abrasive conditions for long tool life

Diamond Coating Ready

  • Ideal substrate for high-performance coated tools

Versatile Across Materials

  • Performs well on graphite, cast iron, and non-ferrous alloys

Broad Application Range

  • Ideal for finishing and semi-finishing tools like drills, end mills, and reamers, as well as wear parts, EDM blanks, seal rings, and industrial knives.
