MAXIMIZE TORQUE TRANSFER AND PRECISION IN LARGE-DIAMETER DRILLING
When your application requires a 9/16″ bore but your equipment is limited to a standard 1/2″ chuck, the Milwaukee 48-89-4634 Silver & Deming bit provides the mechanical bridge without sacrificing performance. Engineered with a Titanium coating to mitigate thermal buildup during high-friction metal drilling, this bit significantly extends service life compared to standard high-speed steel. The Secure Grip™ shank is a critical design element, featuring three flat sides that lock into the chuck to eliminate the rotational slippage often encountered when drilling high-carbon steel or thick gauge aluminum, ensuring every bit of motor torque is delivered to the cutting edge.
- / 135° Split Point eliminates bit walking on curved or flat surfaces for immediate, precision starts.
- / Titanium Coating reduces friction and heat for up to 3X longer life in demanding metal applications.
- / Secure Grip™ 1/2″ Reduced Shank features three flats to prevent spinning under high-torque loads.
- / Versatile geometry optimized for drilling in light gauge metal, high carbon steel, aluminum, wood, and plastic.
