General description These combined taps and drills are designed for efficient drilling, tapping, cutting, deburring, and milling in wood, soft metals, fine aluminum sheets (5-6 mm), and iron. The set includes 6 taps ranging from M3 to M10, allowing for versatile threading applications. The self-centering point eliminates the need for assisted center drilling or punching, enhancing ease of use and precision. Technical specifications Material: High-speed steel (HSS) Hex shank: 6.35 mm (1/4") Metric thread sizes: M3, M4, M5, M6, M8, M10 Pitch: 0.5 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.25 mm, 1.5 mm Quantity: 6 taps Installation Use on a threading machine, such as a lathe. Usage When drilling, inject water simultaneously to cool the drill bit. If cooling is not possible, maintain a lower drilling speed and avoid frequent drilling. Drilling and tapping can be performed in a single step, saving time and improving efficiency. Other information The taps are treated with nitriding for enhanced
