Milwaukee 48‑89‑9223 Shockwave Impact Duty 4‑Piece Step Drill Bit Set

Step Drill Bits with JAM-FREE Performance feature a dual-flute design delivering up to 2X faster hole times, up to 4X longer life, and up to 50% more holes per battery charge than competitors. Ideal for drilling small and large-diameter holes in steel and plastic, these bits are optimized for cordless drills in high speed. The Rapid Strike tip allows for a fast and accurate start that generates less heat, resulting in longer bit tip life. Black oxide coating enhances durability, hole quality, and bit life. Laser-engraved reference marks provide accuracy, and the 3-flat Secure-Grip shank ensures a solid connection with the drill chuck. The 4-piece set includes bits #1, #4, #7, and #12.
