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

Product Information

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.

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

Machine Taps

Letter drill bit sizes: the sizes are indicated in letters, from size A (the smallest) to size Z (the largest). RS PRO hand tap sets are manufactured from high speed steel (HSS), offering excellent corrosion resistance and the ability to withstand higher temperatures. 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. 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.

The drill size chart is a table list standard size drill bits in several measurement systems, including fractional, metric, wire gauge number, and letter. Fractional sizes are measured in inches, while metric sizes are measured in millimeters. The wire gauge and letter systems refer to tool diameters that increase as the wire gauge decreases from #107 to #1 and then continues from A to Z. The decimal equivalents of the diameters are shown in both English and Metric units. 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. RS PRO hand tap sets are manufactured from HSS (high speed steel), offering a durable and reliable selection of tools and are available in a range of thread sizes from M3 to M12.

Testimonials

When manufacturing custom CNC machining parts, holes with screw threads are often required for fastening the finished part or facilitating the building. One of the most common ways to produce the thread holes is to drill a hole of the right size with a drill bit and tap it with a tap. People would need a drill size chart and tap size chart to determine the proper tap drill for a certain thread size or proper tap for an existing hole. 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. 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:
