Milwaukee 1/8″ Thunderbolt Black Oxide Drill Bit 2-Pack 48-89-2714

ENGINEERED FOR MAXIMUM CORE STRENGTH AND RAPID CHIP CLEARANCE

The Milwaukee 48-89-2714 Thunderbolt Black Oxide Drill Bit is engineered to solve the primary failure point of standard bits: core snapping under side-load pressure. By utilizing the Thunderbolt weba significantly thicker core than traditional twist bitsthis 1/8″ bit provides the structural rigidity required for aggressive drilling in metal, wood, and plastic. The parabolic flute geometry is specifically designed to accelerate chip ejection, preventing heat buildup and extending the life of the cutting edge during repetitive cycles. For professionals using high-speed portable drills, the 135-degree split point ensures the bit bites immediately upon contact, eliminating the need for a center punch and preventing walking on curved or polished surfaces.

• / Thunderbolt Web Design: Features a thicker core to provide ultimate strength and protect against breakage caused by side-loading.
• / 135 Split Point: Precision tip starts on contact to prevent bit walking, ensuring accurate hole placement without a pilot hole.
• / Parabolic Flute Form: Clears chips and debris faster than standard flutes to keep the bit cool and maintain cutting efficiency.
• / Black Oxide Coating: Provides essential lubricity and superior corrosion resistance for long-term jobsite durability.
• / 3-Flat Secure Grip Shank: Prevents the bit from slipping in the chuck under high torque loads (available on applicable sizes).
