Suitable for processing through-hole threads, and fast tapping in aluminum, die steel, stainless steel, bronze, hard plastics, etc.. M35 5% cobalt high speed steel features high hardness (HRC65-66) and high red hardness, high wear resistance. 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. High-speed steel bit has high hardness and toughness for wear resistance. Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Suitable lubricant is conducive to cutting or cooling, making cutting easier, improving smoothness and dimensional accuracy. Select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
