Irwin Unibit Step Drills use a unique single flute design to drill perfectly round holes in thin materials quickly and with less effort than a standard bit. Unibits incorporate cutting steps of progressively larger diameter, making it possible to drill up to 13 different hole sizes with a single bit. Once the desired hole diameter is obtained, the hole is automatically deburred by the cutting edge of the next step.
