Milwaukee Thunderbolt Black Oxide 1/16" Drill Bit 12-Pack 48-89-2820

ENGINEERED FOR RIGIDITY AND PRECISION IN HIGH-SPEED DRILLING

The Milwaukee Thunderbolt Black Oxide series addresses the primary failure point of small-diameter bits: core fragility. While standard 1/16" bits are prone to snapping under side-load or high-torque applications, the Thunderbolt web features a significantly thicker core to provide superior structural integrity. This reinforced geometry, combined with a parabolic flute design, ensures that heat is dissipated quickly through efficient chip ejection, extending the service life of the cutting edge. For professionals working on curved surfaces or stainless steel, the 135-degree split point is essential, providing an immediate, precision start that eliminates the need for center punching and prevents bit walking.

• / Thunderbolt Web: Thicker core construction provides ultimate strength and protects against breakage from side-load pressure.
• / 135° Split Point Tip: Starts on contact to keep the bit from walking, ensuring fast and accurate hole placement in metal, wood, and plastic.
• / Parabolic Flute Form: Specially designed to clear chips and debris rapidly, keeping the bit cool and maintaining cutting efficiency.
• / Black Oxide Coating: Provides essential lubricity and corrosion resistance for long-term durability in demanding jobsite environments.
