M2 x 0.4mm Metric Tap Set, Tungsten Steel, Taper and Plug Thread Cutter TD035

Product Information

Hand tap sets are hand tools designed for thread cutting in holes into various materials such as steel allowing you to create a smooth and precise thread for bolts and other materials. They are widely used in applications including: The “M” indicates the “metric diameter” of its thread (see tap drill chart below), which in our case is 4 mm. The second number (0.7) is the pitch which corresponds to the distance between two adjacent threads in millimeters. Finally, 20 is the length of the bolt in mm, measured from the tip of the thread to the bottom of the head (with the exception of oval headed bolts). Some prefer to use somewhat arbitrary but reliable formulas like: “Dtap = Nominal Diameter – Thread Pitch”. This formula works for both metric and imperial units, and for all 60-degree threads (all ISO, DIN, UTS, UNC, UNS, and UNF bolts). The first tap drill chart below is in mm and the next in inches. Both are available as a printable tap drill chart PDF as well.

These durable taps are ideal for use with a tap wrench or drill, providing excellent results for a variety of applications. RS PRO straight flute, taper taps are available in a range of sizes from M2 to M20, offering a wide choice to suit various tasks.

Thread Taps | Thread Tapping Tool | RS - RS Components

RS PRO straight flute hand tap are manufactured from HSS (high speed steel), offering a durable and reliable selection of tools suitable for a range of thread sizes. These versatile hand taps also feature a blue stream tempered finish that reduces friction and produces a fine finish on the threads.

Depending on the type of tap being used and the applications, many can be used with a tap wrench or power tool. For smooth and precise thread cutting, a wrench tool is more suitable, whereas a power tool is suited to rapid thread cutting. Once attached, the hand tap can be rotated to cut the thread in the required material. OverWire is a measuring method to obatin the pitch diameter of threads. It is mostly used when a manufacturer does not have a Go/Nogo gauge for a thread.

Taper taps are often used to create new threads in materials and are ideal for tougher material such as steel, allowing for a gradual and smooth tapered cut. Second and plug taps have a shorter taper and more threads and are often used to create and re-cut threads at a faster rate. Unfortunately, due to the shape it can’t create a thread all the way to the end of the hole. So next comes the bottoming tap that has the capacity to do this. However, the bottoming tap cannot start the threading on an uncut hole, so it can only take part in the cutting process as the second or third tap. The taper tap is only used in certain situations such as when the material is very hard or the hole is too small. The taper tap features a smooth diameter transition that allows for a less aggressive cutting action. This minimises the risk of damaging the drilled hole. If the taper needs to go first, the intermediate tap follows second and the thread is finished with the bottoming tap.
