Milwaukee 27/64" Thunderbolt Black Oxide Jobber Length Drill Bit 48-89-2727

REINFORCED CORE TECHNOLOGY FOR HIGH-TORQUE DRILLING APPLICATIONS

Standard drill bits often fail at the web when subjected to side-load pressure, but the Thunderbolt design addresses this structural weakness head-on. By utilizing a thicker core, these bits provide the rigidity needed for drilling through tough alloys and curved surfaces where standard bits might snap. The parabolic flute geometry is engineered to eject chips rapidly, reducing heat buildup—the primary enemy of bit longevity. For professionals using high-torque cordless drills, the 3-flat shank ensures the bit stays locked in the chuck, preventing the frustrating spin-out that ruins both the bit and the workpiece.

• / Thunderbolt Web Design: Features a thicker core than standard bits to provide ultimate strength and protection against side-load breakage during heavy-duty use.
• / 135° Split Point: Precision-ground tip starts on contact to eliminate walking, ensuring accurate hole placement without the need for a center punch.
• / Parabolic Flute Geometry: Specifically engineered to clear chips and debris quickly, keeping the bit cool and extending the cutting life.
• / 3-Flat Secure-Grip™ Shank: Eliminates bit slipping in the drill chuck, providing maximum torque transfer and control.
• / Black Oxide Coating: Provides essential lubricity and corrosion resistance, reducing friction and heat during high-speed drilling.
