Milwaukee 27/64" Thunderbolt Black Oxide Drill Bit 48-89-2827

ENGINEERED FOR EXTREME DURABILITY AND SUPERIOR CHIP CLEARANCE

When drilling through tough metals or curved surfaces, the primary failure points are typically side-load breakage and excessive heat buildup. This Thunderbolt series bit is engineered with a significantly thicker core than standard jobber bits, providing the structural integrity required to withstand high-torque applications without snapping. The 135-degree split point ensures immediate engagement upon contact, preventing the bit from walking and allowing for precise hole placement even in portable drilling scenarios. By integrating a parabolic flute design, this bit manages heat and debris more efficiently, ensuring a longer service life and cleaner results in professional-grade materials.

• / Thunderbolt Web: Features a thicker core to protect against side-load breakage and provide ultimate strength in demanding applications.
• / 135° Split Point: Starts on contact to prevent the bit from walking, ensuring fast and accurate hole placement without a center punch.
• / Parabolic Flute: Clears chips and debris rapidly to keep the bit cool and maintain cutting efficiency over extended use.
• / 3-Flat Secure-Grip Shank: Specifically designed to prevent the bit from slipping in the chuck, with a reduced diameter for 3/8" compatibility.
• / Black Oxide Coating: Provides essential lubricity and resists corrosion to maintain performance in wood, metal, and plastic.
