The Milwaukee SHOCKWAVE™ Impact Duty™ 3-Piece Step Bit Kit (Model 48-89-9254) is built for professional electricians and contractors who need fast, accurate holes in sheet metal, electrical panels, and enclosures — day in, day out. Including Step Bits #1, #2, and #4, this kit covers the most common hole sizes on the job site in a single purchase. Optimised for impact drivers yet fully compatible with drill/drivers, these bits feature a Rapid Strike™ tip for fast, walk-free starts and a dual spiral flute design that cuts up to 2× faster than competitive step bits. The titanium aluminium nitride (TiBone™) coating delivers 5× longer life, while the optimised SHOCKZONE™ shank absorbs torque peaks to prevent early shank breaks — keeping you drilling longer and replacing bits less often. Made in the USA with global materials.
