Suitable for processing through-hole threads. For fast tapping in aluminum, die steel, stainless steel, bronze, hard plastics, etc.. Titanium coating provides excellent corrosion resistance and improves wear resistance. Used on drilling machines, tapping machines, CNC and milling machines. Use with tapping oil to get higher quality threads and more durable taps. Machine taps are suggested to be used with tap chucks with overload protection. Not recommended for hand use and electric drill tapping. Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Chips are not easy to stick to the tool. Cobalt high speed steel tool features high hardness (HRC65-66) and high red hardness, high wear resistance, good for general purpose applications. Suitable Lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
