OPTIMIZED IMPACT-READY METAL BORE PERFORMANCE
The Milwaukee 48-89-9211 11 Step Drill Bit is engineered for the high-demand professional who requires maximum efficiency from their cordless fleet. By utilizing a dual-flute geometry specifically tuned for high-speed operation, this bit eliminates the common frustration of jamming and stalling in heavy-gauge metals. The integration of a Rapid Strike tip ensures your entry point is dead-accurate with zero walking, while the specialized Black Oxide finish maintains thermal stability, delivering up to 50% more holes per battery charge compared to standard competitive bits.
- / Rapid Strike Tip: Initiates fast, accurate starts on contact while generating significantly less heat for extended bit and battery life.
- / Jam-Free Performance: Optimized dual-flute design provides greater speed and control in high-speed cordless drilling applications.
- / Impact Rated 1/4″ Hex Shank: Offers extreme versatility for quick-change impact drivers while ensuring a slip-free grip in standard drill chucks.
- / Laser-Engraved Markings: Permanent reference marks allow for precise hole sizing without the guesswork, even after heavy use.
- / Black Oxide Finish: Enhances durability and corrosion resistance while improving capacity to hold drilling lubricants for cleaner finishes.
