roller bits are tools for boring into rock and earth. They are used to drill blasting holes and penetrate both soft and hard rock materials. Products are also used in many other mining, quarrying, tunneling, construction, geological exploration, and blasting applications. Roller bits can be classified as chiseling bits, tapered or threaded cross-style bits, anchor bits or self-drilling anchor systems, blasting furnace taping hole bits or rods, or coal cutter bits. They feature a hollow body with multiple, outward-extending wings.
