IRWIN Tools Step Drill Bit for Professionals, 1/8-Inch to 1/2-Inch

The Irwin 10231 Unibit #1 is a versatile 13-step drill bit designed to efficiently create round holes in thin materials, ranging from 1/8-inch to 1/2-inch in diameter, with steps incremented by 1/32-inch. This unique design significantly reduces the time spent switching between drill sizes, as each smaller bit serves as a pilot for the next.

One of the standout features of this drill bit is its patented single-flute cutting edge, which enhances control throughout the drilling process, ensuring a consistently true round hole every time. This functionality makes it an excellent choice for drilling into various thin materials, including stainless steel, copper, brass, aluminum, plastic, and laminates.

The SpeedPoint tip is another innovation that increases efficiency; it penetrates faster than earlier versions of Unibits and minimizes the risk of the drill bit walking during use. Additionally, the 3-flatted hex shank design prevents slippage in the drill chuck, ensuring that the bit remains securely in place while you work.

For convenience, drill diameters are clearly etched along the flute of the bit, making size identification quick and effortless. This thoughtful detail helps users maintain accuracy and streamline their workflow. With these features combined, the Irwin 10231 Unibit #1 not only enhances drilling precision but also improves overall efficiency for any project involving thin materials. Whether you're a professional tradesperson or a DIY enthusiast, this Unibit promises to be an essential addition to your tool collection.
