S1356LLZ-28
Product Description
The driving tooth is a rock-breaking tool for coal mining machines, tunnel boring machines and other equipment. It is welded with a low-alloy steel blade body (such as 42CrMo, 35CrMnSi) and a cemented carbide blade head (tungsten-cobalt alloy).
Product advantages
Efficient rock breaking: Tungsten carbide bits (HRA≥85) can cut rock formations with a hardness of less than 12 degrees, and the rock breaking efficiency is 20%~30% higher than traditional bits. Long-life design: Using passivation technology, the service life is 5 to 6 times that of blade bits of the same pecification.

Classification application
The conical tooth head has strong impact resistance and is suitable for hard rock or semi-coal rock working conditions. Low cutting resistance and used for coal seam mining.
Scope of application
Coal mining: Suitable for coal mining machines, boring machines and other equipment, covering coal seams, hard rocks and semi-coal rock formations. Tunnel engineering: such as shield machines and rotary cutter picks (such as BZ47 series), used for tunnel boring and foundation construction.
Product performance
Impact resistance: Special tooth head design (such as tapered, curved) distributes stress, reduces the risk of broken shank, and adapts to Complex rock conditions. Process verification: Through hot mounting process and alloy composition optimization (such as increasing Co content), the comprehensive performance reaches the international level, and the domestic replacement cost is reduced by 30% to 50%.
