MAXIMUM EFFICIENCY HOLE PRODUCTION

Engineering a solution for high-volume mechanical and electrical rough-ins, the Milwaukee 4-Piece Step Drill Bit Set is purpose-built to maximize the performance of your cordless fleet. By integrating a dual-flute geometry, these bits significantly mitigate the heat build-up that compromises standard consumables, ensuring your technicians spend less time swapping bits and more time on the trigger. Optimized for high-speed drilling, this set offers a jam-free experience that translates directly to higher ROI on every job site through reduced downtime and superior hole quality.

  • / Rapid Strike Tip: Ensures immediate, accurate starts without walking, reducing heat generation for extended bit life.
  • / Dual-Flute Design: Engineered for cordless speed, delivering up to 2X faster hole times and 50% more holes per battery charge.
  • / Black Oxide Coating: Provides enhanced durability and corrosion resistance while maintaining edge sharpness through heavy use.
  • / Laser-Engraved Marks: Permanent reference marks allow for high-visibility sizing while drilling for total accuracy.
  • / Secure-Grip Shank: The 3-flat design eliminates bit slippage in the drill chuck, ensuring maximum torque transfer.
