Suitable for processing through holes or shallow holes. For tapping aluminum, die steel, stainless steel, bronze, hard plastics. High-speed steel tool has high hardness and toughness for wear resistance. Features just the base substrate without any additional coatings, good for wide ranges of applications. 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 collets with overload protection. Hand use is easy to cause breakage to the tap due to uneven force. 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. M35 5% cobalt high speed steel tool features high hardness (HRC65-66) and high red hardness, high wear resistance. 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.
