Milwaukee 21/64" Thunderbolt Black Oxide Drill Bit 48-89-2822
ENGINEERED FOR EXTREME DURABILITY AND PRECISION DRILLING
The Milwaukee 48-89-2822 21/64" ThunderboltĀ® Black Oxide Drill Bit is designed to solve the most common failure point on the jobsite: bit breakage. By utilizing the proprietary ThunderboltĀ® web, which features a significantly thicker core than standard jobber bits, this bit provides the structural integrity needed to resist side-load snapping during aggressive drilling. The parabolic flute design is a critical mechanical advantage, facilitating rapid chip evacuation to prevent heat buildupāthe primary enemy of bit longevity. Whether you are drilling through stainless steel, wood, or curved surfaces, the 135Ā° split point ensures an immediate start without the need for a center punch, maintaining high-precision hole placement every time.
- / ThunderboltĀ® Web Design: Thicker core provides ultimate strength and protects against side-load breakage during heavy-duty applications.
- / 135Ā° Split Point Tip: Starts on contact to prevent walking, ensuring fast and accurate hole placement without the need for a pilot hole.
- / Parabolic Flute Geometry: Clears chips and debris faster to keep the bit cool and extend the sharp life of the cutting edge.
- / 3-Flat Secure-Grip Shank: Prevents the bit from slipping in the chuck under high torque, maximizing power transfer and safety.
- / Black Oxide Coating: Provides superior lubricity and corrosion resistance for smoother drilling in tough jobsite materials.
