#4 Black Oxide Step Drill Bit (12-Steps), 3/16 in. - 7/8 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 provides up to 2X faster hole-making times, up to 4X longer 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 ensures quick, precise starts that produce less heat, which contributes to a longer lifespan for the tip. Additionally, the black oxide coating improves durability, hole quality, and overall bit longevity. For added convenience and precision, each bit is marked with laser-engraved reference points that are visible during drilling.
