Step drill bits are widely used in plumbing and general construction to make round holes in soft materials. However, they can also be applicable for very thin stainless steel, aluminum, brass, copper and other metals. These versatile tools are particularly handy when it comes to enlarging holes that have already been drilled. A step drill bit features a unique staircase profile that allows it to cut holes of different diameters. It has a smaller pilot drill point that drills the initial small holes, and to be able to achieve the desired size of the hole it’s recommended to advance the drill bit further into the material. Step drill bits are usually coated in a titanium-nitride coating that helps minimize heat build-up, enhance surface hardness and ensure long-lasting service.
Whether you are a professional contractor, a plumber or a hobbyist working on your own construction project, high-quality step drill bits offered on our website will give you the reliability and versatility you need to perform your tasks as easily and effectively as possible. Now you can create perfect round holes, enlarge the existing ones or deburr holes left by other bits using only one tool – and that’s the step drill bit. Here, we carry a full line of first-rate step drill bits that are made from the sturdiest materials such as high-speed steel to bring the ultimate in performance and wear resistance. Most step drill bits showcased in our online store have a flatted shank or hex shank that allows to avoid slipping in drill chuck.
