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.
