Made with ultra-coarse-grained carbide cutter heads of high hardness and fitted with high-quality alloy steel teeth, the entire body is quenched and tempered, and the head is strengthened by heat treatment. It offers high hardness and excellent toughness. It can perfectly handle high-frequency impact and crushing in coal seams, interlayers, and thin rock layers, effectively preventing common downhole problems such as tooth breakage, tooth loss, and tooth detachment, and is suitable for harsh downhole working conditions.
Designed with a specialized imitation-form cutting-tooth profile, it features precise cutting-in angle and low coal-cutting resistance, enabling rapid separation of coal seams and efficient crushing of mixed coal-rock strata. It is suitable for continuous cutting by coal mining machines and rapid tunneling by roadheaders, effectively improving underground mining and tunneling progress, reducing no-load equipment loss, and enhancing overall construction productivity.
