| ▲The products are widely used in mining roadway support drilling, mining rock drilling, coal mine rock roadway, bridge excavation and other engineering construction. |
| ▲when the drill pipe is used with the drill bit, under normal circumstances the drill pipe should be larger than the diameter of the drill pipe, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of stuck drilling,holding and other phenomena, drilling should be stopped immediately or slowly drilled after drilling to ensure that the drill pipe does not bend and deform. |
