This set includes three standard step drill bits that replace 28 individual drill bits allowing for you to spend more time working, than swapping out drill bits.
Our step down drill bit made of high-speed steel with titanium coating for added durability and bit life. Suitable to drill though plastic, aluminum, copper, stainless steel, and many other types of sheet metal.
Two-flute spiral design provides faster, smoother cutting without walking and a tri-flat shank to ensure a firm grip. Our titanium 2 step bits for metal are perfect for all your DIY, general building, and engineering tasks.
Comes with one 3/16-inch to 1/2-inch six-step bit, 1/4-inch to 3/4-inch nine-step bit, and 1/8-inch to 1/2-inch 13-step bit.
Cuts through steel, sheet metal and other surfaces with only a small amount of pressure and deburrs as you drill. Our unibit step drill bit is compatible with most drills on the market.
