1. Long service life. Its service life is 1-1.5 time than traditional cutting teeth;
2. High efficiency. Its working efficiency is 2.5 time than traditional cutting teeth;
3. Good energy efficiency. Replacing frequency dropped substantially, shortens the coal winning machine downtime,reduce the mining cost.
Our coal cutting picks bits are in all sizes, mainly used in coal mining and roadway, tunnel, the ground trenching engineering excavation, such as the main blending coal winning machine, boring machine, milling planer and other equipment.
