Drilling and tunneling equipment tools

The tunneling drill rig tools are important equipment widely used in tunneling and mining projects. They mainly use single hexagonal cross-section drill rods made of high-strength alloy steel, which have good toughness and bending strength. The drill bit is the part that directly breaks the rock, and there are various shapes and specifications available according to different rock types and operational requirements, typically with a drill bit diameter ranging from 35 to 48 mm. The coupling sleeve is used to connect the drill rod and the drill bit, ensuring a secure and reliable connection.
