Milwaukee Step Drill Bit 6-Piece Set 48-89-9224
Model Number: MIL48899224
ELIMINATE BINDING AND MAXIMIZE RUNTIME WITH JAM-FREE STEP BITS
Engineered for the high-torque demands of modern cordless platforms, this 6-piece step bit set solves the primary failure point of traditional drilling: heat-induced binding. The dual-flute geometry is precision-ground to clear chips faster, reducing friction and allowing your M18 or M12 drill to maintain peak RPM without bogging down. By optimizing the cutting angle, these bits deliver up to 50% more holes per battery charge, ensuring that your high-output batteries are utilized for maximum productivity rather than fighting resistance. The black oxide coating serves as a critical thermal barrier, preserving the cutting edge through repeated cycles in heavy-gauge steel and rigid plastics.
- / Jam-Free dual-flute design provides superior speed and control while preventing the bit from catching in high-speed applications.
- / Rapid Strike™ tip ensures fast, accurate starts without walking and generates significantly less heat for extended tip life.
- / 3-Flat Secure-Grip™ shank eliminates bit slippage in the chuck, ensuring 100% torque transfer during heavy drilling.
- / Laser-engraved reference marks provide permanent visibility of hole sizes, allowing for precise depth control even while the bit is spinning.
