Techgong tunnelling tools are ubiquitous in the construction of the tunnels of Chinas vast rail network. They have proven highly effective in dealing with calcified layers and hard cobbles as well as large gravel and pebble content. They have also been effective in sandstone, quartz and granite conditions.

 

Techgong provide a wide range of cutters, scrapers and rippers as well as customising bits and wear materials to suit specific client applications. We also supply picks, sleeves and holders for road headers.
