M3 x 0.5mm Metric Tap Set, Tungsten Steel, Taper and Plug Thread Cutter TD034

Product Information

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. Yes, these RS PRO hand set taps are supplied with a durable polypropylene case offering a durable and secure storage solution. 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: Fractional drill bit sizes: the sizes are written as irreducible fractions. ANSI B94.11M-1979 sets size standards for jobber-length straight-shank twist drill bits from 1/64 inch through 1 inch in 1/64 inch increments.

Got the tool tray - really good fabrication - many thanks – we were really impressed with the finish / welds etc. To all the staff at Sams Fabrications I would like to send you a big thank you for the extra effort you put in to getting our product to us in such a timely manner. Introducing HSS (high speed steel) straight flute, taper hand taps from our trusted own brand RS PRO, a range of tools for cutting thread into material such as metal bolts. 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. RS PRO hand tap sets are manufactured from high speed steel (HSS), offering excellent corrosion resistance and the ability to withstand higher temperatures. They also feature a blue stream tempered finish helping to reduce friction and produce a cleaner thread.Number drill bit sizes: the sizes are indicated in numbers, range from size 80 (the smallest) to size 1 (the largest). Number and letter sizes are commonly used for twist drill bits rather than other drill forms. As per the ISO metric screw thread standard, the thread depth should be 0.614 x pitch, which is why a smaller pitch number also results in a lower thread depth value. Now engineers can sit down and manually calculate the right tap drill. Or they can consult a tap drill chart like those found in the next section. Letter drill bit sizes: the sizes are indicated in letters, from size A (the smallest) to size Z (the largest).

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. Thread Geometry And Drilling The Hole The drill size chart contains tools up to 1.5 inches in diameter, but larger tools are also commonly used. Introducing HSS metric hand tap sets from our trusted own brand RS PRO, a range of sets with tools ideal for cutting thread into material such as metal bolts. The durable taps included in these sets are ideal for use with a tap wrench or drill, providing excellent results for a variety of applications. The sets include the 3 most common types of tap including a taper tap, second tap and bottom tap, allowing you to carry out a range of tapping tasks from starting a new thread to cutting a straight thread as soon as the tap enters the hole.RS PRO hand tap sets are manufactured from high speed steel (HSS), offering excellent corrosion resistance and the ability to withstand higher temperatures.

For each thread count, the equivalent thread pitch is provided and for metric taps, the approximate thread count is shown based on the pitch. Lastly, the recommended tap drill size is provided for each standard tap size. This size drill bit should be used for drilling the initial hole that will then be tapped. I have attached a drawing of another piece of equipment, could you have a look at it and quote for me. 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. Tap Drill Chart (mm and inches) 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).The data chart below shows the standard metric ‘coarse’ threads and their drill holes sizes were are most commonly used when tapping sheet metal fabrications.
