DIYers and professionals, this step drill bit is a game-changer for clean, precise holes! Made from M35 Cobalt High-Speed Steel with a nano-blue coating that reduces friction and extends tool life. The four spiral flute design efficiently clears chips and reduces heat buildup during drilling. It covers three step sizes from 3/16 inch up to 1-3/8 inches, with popular sizes like 7/8, 1-1/8, and 1-3/8 inches clearly labeled. The 3/8 tri-flat shank prevents slipping in your drill chuck. Perfect for drilling through 1/8 inch thick stainless steel, metal sheets, wood, plastic, aluminum, and copper. The stepped design means you can create multiple hole sizes with one bit, making it super versatile for various projects. Whether you're working on metal fabrication, woodworking, or general repairs, this bit delivers smooth, burr-free holes without the need for multiple drill bits. The quality construction means it will last through many projects without dulling quickly. Comes with a satisfaction guarantee - if the hex shank snaps, they'll replace it. Seriously worth adding to your toolbox if you do any kind of drilling work!
