Our patented Ice Bits are equipped with dual carbide cutter, and a single hollow flute body milled from a single piece of alloy steel for strength. The carbide cutter is brazed to a steel body with a hardened steel cutting edge. This combination allows the icebits to bore ice quickly and easily while leaving little or no residue producing a clean smooth hole. Our Ice Bits are self feeding and requires less torque. It can be used with electric, air, or gasoline powered drill motors and impact wrenches. Custom made to order.
