How are drill bits classified?



The drill rods can be divided into hydraulic rock drill rods and pneumatic rock drill rods based on the different supporting equipment. Hydraulic rock drill rods have a wider application and higher quality requirements. Depending on the application environment of the drill rods, they can be classified into surface drilling rig supporting drill rods and underground rock drilling trolley supporting drill rods. The underground working environment is more complex, especially due to the erosion from mine water and slag, which imposes higher requirements on the drill rods. Based on the thread form of the drill rods, they can be divided into male thread drill rods and female thread drill rods, with male thread drill rods being more widely used.
