Key Features

• 5/16" (7.94 mm) Diameter: A versatile size commonly used for drilling holes to mount brackets, hangers, clamps, and various hardware on passenger cars, light trucks, and equipment.
• High-Speed Steel with Black Oxide Finish: Offers enhanced heat and wear resistance for drilling through mild steel, aluminum, and non-ferrous metals, while also reducing friction and providing surface corrosion resistance.
• 135° Split Point: This self-centering point minimizes bit walking on curved or painted surfaces, often eliminating the need for a pilot hole or center punch and improving drilling accuracy from the start.
• Optimized Flute Design & Reinforced Web: Engineered for efficient chip evacuation, which reduces heat buildup and adds core strength to the bit, helping to prevent breakage during continuous or high-duty-cycle operations.
• 3-Flatted Shank: Designed to prevent bit spin in both keyed and keyless chucks, ensuring stable operation and improved torque transfer across cordless drills, drill presses, and magnetic base drills.
