Made of high-hardness ultra-coarse-grained hard alloy cutter bits, matched with high-quality alloy steel bodies, and processed through overall tempering and head hardening heat treatment, it offers high hardness and excellent toughness. It can perfectly handle high-frequency impact crushing of coal seams, interlayers, and thin rock layers, effectively preventing common downhole problems such as tooth breakage, tooth loss, and tooth shedding, and is suitable for harsh downhole working conditions.
With a professional bionic cutting tooth profile design, the cutting-in angle is precise and the coal-breaking resistance is low, enabling rapid peeling of coal seams and crushing of coal-rock mixed layers. It is suitable for continuous cutting of coal mining machines and rapid tunneling operations of roadheaders, effectively improving underground mining and excavation progress, reducing equipment idling loss, and enhancing overall construction productivity.
