Milwaukee 11/32" Thunderbolt Black Oxide Drill Bit 48-89-2838
REINFORCED THUNDERBOLT WEB FOR MAXIMUM RIGIDITY AND CORE STRENGTH
Engineered to solve the common failure point of standard high-speed steel bits, the Milwaukee Thunderbolt series utilizes a significantly thicker core to provide ultimate protection against side-load breakage. This 11/32" bit is optimized for the high-torque demands of cordless portable drills, where sudden binding can easily snap thinner bits. The parabolic flute geometry is a critical mechanical feature, designed to accelerate chip evacuation and minimize heat buildup, which directly extends the cutting life of the black oxide treated edges. Whether you are drilling through carbon steel, wood, or PVC, the 135-degree split point ensures the bit bites immediately on contact, eliminating the "walking" that ruins precision layouts on curved or polished surfaces.
- / Thunderbolt® Web Design: Thicker core provides superior strength and resists snapping under heavy side-load pressure.
- / 135° Split Point Tip: Starts on contact to prevent bit walking and ensures fast, accurate hole placement without a center punch.
- / Parabolic Flute Geometry: Clears chips and debris rapidly to keep the bit cool and maintain cutting efficiency in deep-hole applications.
- / 3-Flat Secure-Grip™ Shank: Machined flats prevent the bit from spinning or slipping inside the chuck during high-torque drilling.
- / Black Oxide Coating: Provides essential lubricity and corrosion resistance for long-term professional use.
