Set of 6 high-speed steel drill bits and taps, M3-M10 thread, 1/4 inch hex shank

These taps are made of nitrided high-speed steel, giving them high hardness and excellent corrosion resistance. Their helical flute design optimizes chip evacuation. Available in six different sizes, from M3 to M10, they allow for the creation of various threads. These taps also feature a drilling function, allowing simultaneous tapping and drilling for simplified use. Their use requires a machine tool, and they generally offer increased accuracy by minimizing human error.
