The Matco Tools 4-pc Extra-Large Hyper-Step Drill Bit Set, No. DB4HSXL, is designed to cut faster and is ideal for cutting sheet metal and hardened metals like broken fasteners. The extra-large set includes sizes 11/16", 3/4", 7/8", and 1" with flats and 1/2" reduced shanks. The patented Hyper-Step design in large sizes eliminates the need for up to two pilot holes that traditional drill bits require and stays sharp up to four times longer compared to conventional and other specialty tip designs, the company says.
