18.5mm Drill Bit 1/2" Reduced Shank 4341 High-Speed Twist HSS Nitriding Black 135° for Light-Duty Soft Metal Aluminum Alloy Wood Plastic

Key Features

• SIZE Cutting edge diameter 18.5mm, shank diameter 1/2 inch, total length 150mm/5.91 inch, flute length 80mm/3.15 inch, small and easy to carry, suitable for various material
• MATERIAL Precision-treated 4341 high-speed steel delivers superior hardness, making it ideally suited for high-friction applications. The material delivers exceptional wear resistance, while its nitriding black finish provides enhanced oxidation and corrosion protection, significantly extending tool service life
• 135-DEGREE SPLIT-POINT TIP Provides excellent processing stability, is suitable for hard metal, and can effectively reduce the risk of cutting edge chipping, improving drilling efficiency and hole quality.
• WIDE APPLICATIONS These drill bits are specifically designed for metalworking applications, effectively drilling through various metals, including thin steel, thin stainless steel, aluminum, copper, and brass. (They are not suitable for application with super-hard metals)
• TIP Use a slower drill speed. Drill a smaller hole first to ensure precise positioning and prevent drill deviation. When drilling thick workpieces, use water or coolant to lower the temperature and prevent the drill bit from overheating.
