Alloy drill bits for rock drills come in three types: single - chisel type, cross - chisel type, and X - chisel type. The single - chisel type is suitable for drilling rock layers with low hardness using light - duty rock drills and is easy to grind. The cross - chisel type and X - chisel type are suitable for use with rock drills that have a large impact energy. They are used to drill fractured rock layers and highly abrasive rock layers and have strong resistance to radial abrasion.
