Milwaukee 27/64" Thunderbolt Black Oxide Jobber Length Drill Bit 48-89-2735

REINFORCED CORE TECHNOLOGY FOR MAXIMUM DRILLING UPTIME

The Milwaukee 48-89-2735 is engineered to solve the most common failure point in jobsite drilling: bit snapping under side-load pressure. By utilizing the proprietary Thunderbolt® web—a significantly thicker core than standard jobber bits—this bit maintains structural integrity when drilling through tough alloys or curved surfaces where deflection is inevitable. The 135° split point eliminates the need for a center punch, biting into the material immediately to prevent walking and ensure hole concentricity. For high-volume applications, the parabolic flute geometry is critical, ejecting chips rapidly to minimize heat buildup and extend the life of the cutting edge, providing a superior professional ROI compared to standard high-speed steel alternatives.

• / THICKER WEB DESIGN: Engineered with a reinforced core to provide ultimate strength and protect against breakage during heavy side-load applications.
• / 135° SPLIT POINT: Delivers a precision start on contact, preventing bit walking for faster, more accurate holes in metal, wood, and PVC.
• / PARABOLIC FLUTE: Specifically designed to clear chips and debris quickly, reducing friction and heat for a longer-lasting cutting edge.
• / 3-FLAT SECURE-GRIP™ SHANK: Eliminates bit slipping in the chuck, ensuring maximum torque transfer and safety during high-torque drilling.
• / BLACK OXIDE COATING: Provides essential lubricity and corrosion resistance, maintaining performance in demanding jobsite environments.
