The DEWALT DWA1790IR set includes three step drill bits ranging from 1/8" to 7/8". They are made of high-speed steel with a titanium nitride (TiN) coating for durability. The bits are impact rated, meaning they are designed to withstand the high torque of impact drivers. The manufacturer part number is DWA1790IR.
