Feature

●Tap Size: 4-40 UNC thread, 2B thread tolerance grade Straight flute design, downward shavings removal, precise and fast tapping High hardness and toughness for wear resistance
●M42 High Speed Steel: M42 is a high speed steel alloy with 8% or 10% cobalt, which has a red hardness better than traditional high-speed steel. M42 is less likely to chip when used for intermittent cutting than the same tool made with carbide hardness
●Application: Suitable for processing through holes or shallow stop holes. Ideal for drilling and tapping materials under HRC30 such as alloy steel, cast iron, stainless steel, brass, and aluminum
●Easy to use: Used in drilling machines, tapping machines, CNC, milling machines. When used with tapping oil, you get threads and more durable taps. It has only a base board without additional coating, suitable for a wide range of applications
●Tip: It is recommended to use the machine tap with a tap collet with overload protection. We do not recommend using your hands or using an electric drill, as the taps are prone to breaking. Add coolant during tapping and apply rust resistant oil for post-use maintenance
