When it comes to the cutting on the coral stratum and rock stratum containing hard coal gangue, the cutter pick made of ordinary alloy will be reluctantly qualified and is easy to be damaged and broken. In order to solve this tough problem, we have developed the new style of cutter pick with carbide tips.
The carbide tip for coal cutter picks is typically made of carbides with designations of JZ10CC and XR12CC, and has excellent breaking tenacity and heat resistance. Cutter picks with our carbide tips are applicable for both coal cutters and TBM cutters.
