Using high-hardness ultra-coarse-grain carbide cutter tips, paired with high-quality alloy steel cutter bodies, and subjected to overall tempering and head strengthening heat treatment processes, they offer high hardness and excellent toughness. They can perfectly withstand high-frequency impact crushing in coal seams, interlayers, and thin rock layers, effectively preventing common downhole problems such as cutter tip breakage, tooth breakage, and blade shedding, and are suitable for harsh underground working conditions.
The cutter body surface is treated with precision wear-resistant strengthening, providing outstanding wear resistance, corrosion resistance, and high-temperature performance. For working environments with heavy underground dust, high humidity, and strong abrasion, it can continuously maintain stable cutting performance, greatly reduce wear speed, extend the service life of components, and reduce the cost of frequent replacement.
