Grade HB-512 stands out for its high hardness and abrasion resistance, designed to meet the toughest demands in finish machining. Ideal for applications like drills, endmills, and reamers, as well as wear parts like EDM blanks, wire guides, and sandblast nozzles, HB-512 ensures minimal shock while delivering long-lasting tool life. It is perfect for working with stainless steels, titanium alloys, and heat-resistant steels where wear resistance is critical.
Exceptionally hard material for use in tools that require long-lasting edge retention and resistance to wear.
Provides superior performance with minimal shock for finish machining and high-quality surface finishes.
Ideal for machining tough materials, including stainless steels, titanium alloys, and heat-resistant steels.
Perfect for applications like EDM blanks, wire guides, and sandblast nozzles where wear resistance is paramount.
