Made of ultra-coarse-grained hard alloy cutter teeth with high hardness, matched with high-quality alloy steel tooth bodies, and processed through overall tempering and tooth-head strengthening heat treatment, they offer high hardness and strong toughness. They can perfectly handle high-frequency impact and crushing of coal seams,夹矸, and thin rock layers, effectively preventing common underground problems such as tooth breakage, tooth fracture, and tooth loss, and are suitable for harsh underground working conditions.
