Adopted high-hardness ultra-coarse-grained hard alloy cutter bits, matched with high-quality alloy steel tooth bodies, and subjected to 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, interlayers, and thin rock formations, effectively preventing common problems such as tooth breakage, tooth loss, and flake detachment in downhole operations, and are suitable for harsh underground working conditions.
Designed with a professional imitation-shaped cutting tooth profile, they offer precise cutting angles and low coal-cutting resistance, enabling rapid separation of coal seams and crushing of coal-rock mixed strata. Suitable for continuous cutting by coal mining machines and rapid tunneling operations by roadheaders, they effectively improve underground mining and tunneling progress, reduce idle wear and energy loss of equipment, and enhance overall construction productivity.
The tooth body surface undergoes precision wear-resistant strengthening treatment, providing excellent wear resistance, corrosion resistance, and high-temperature resistance. For working environments with heavy dust, high humidity, and strong abrasion underground, it can continuously maintain stable cutting performance, significantly reduce wear speed, extend the service life of components, and reduce frequent replacement costs.
