SIZE: Cutting edge diameter: 14mm, shank diameter: 1/2 inch, total length: 150mm/5.9 inch, flute length: 56.388mm/2.22 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.
