Application
Tungsten carbide button is often used as drilling tools for shearers and mining machinery tools. They can also be used in heavy excavator bits.
Grade Equal to ISO Category Number Density (G/cm3) Hardness (HRA) Bend Strength (TRS/N/mm2)
Feature
Tungsten carbide button has high wear resistance and impact toughness, and has higher drilling speed than similar products. Tungsten carbide button bit has a long service cycle of passivation, and its non-grinding life is about 5-6 times of the grinding life of the same diameter drill bit, which is conducive to saving auxiliary working hours, reducing physical labor of workers and speeding up the project efficiency.
