The cutting teeth are made of high-hardness ultra-coarse-grained hard alloy cutters, matched with high-quality alloy steel tooth bodies. Through overall tempering and head strengthening heat treatment, they offer high hardness and excellent toughness. They can perfectly handle high-frequency impact crushing in coal seams, mixed rock, and thin rock layers, effectively preventing common downhole problems such as tooth breakage, tooth loss, and tooth shedding, and are suitable for harsh underground working conditions.
The tooth body surface undergoes precision wear-resistant strengthening treatment, providing outstanding resistance to wear, corrosion, and high temperatures. Designed for underground working environments with heavy dust, high humidity, and strong abrasion, they can maintain stable cutting performance continuously, greatly reduce wear speed, extend the service life of components, and reduce the cost of frequent replacement.
