A step bit, also known as a unibit, is a drill bit with a stepped profile that allows for drilling a range of hole sizes with a single bit. The bits are typically made of high-speed steel (HSS) and are available in a variety of sizes and shapes, including conical and hex. Step bits are commonly used in metalworking, woodworking, and plumbing applications.
Step bits offer several advantages over traditional drill bits, including the ability to drill holes in a variety of sizes without having to change bits. This can save time and effort, especially when drilling multiple holes of different sizes. Additionally, step bits are less likely to wander or slip than traditional drill bits, making them ideal for drilling in thin or delicate materials. The stepped profile of the bit also helps to create clean, burr-free holes.
