#1 Black Oxide Step Drill Bit (13-Steps), 1/8 in. - 1/2 in.

Step Drill Bits with JAM-FREE Performance are designed for optimal use with cordless drills at high speed. They feature a dual-flute design that offers up to 2X quicker hole-making times, up to 4X increased lifespan, and up to 50% more holes per battery charge compared to other options. These bits are perfect for creating both large and small-diameter holes in materials like steel and plastic. The Rapid Strike tip enables quick, precise starts while producing less heat, which contributes to a longer lifespan for the bit tip. The black oxide coating further improves durability, hole quality, and the overall life of the bit. For ease of use and precision, each bit is marked with laser-engraved reference points that are visible during drilling. The 3-flat Secure-Grip shank guarantees a firm connection with the drill chuck.
