There are a number of different types of thread taps that are used to cut threads in holes drilled into round stock, flat work pieces, or castings. These taps are made to cut specific types of internal threads. If a user attempts to use the wrong tap, it can lead to problems such as breakage and burrs. Understanding the various types of taps and their applications enables users to choose the right tap for their application.
Threading tool kits are used to create threads inside a hole. Thread tapping is done by making a helical groove on a hole by the use of hand tools or powered equipment like lathes. The thread tap is inserted into the hole and is rotated while gradually completing the thread. The process of threading is to be taken up in two stages, first by making a starting guide called bottom shoulder brazed to the tool and second by the creation of the actual thread.
Threading tool kit are used in Hole Making Operations. Depending on the type of material being made and the particular end use, these may be plain, taper, plug, bottoming etc. The size used varies from 0.50 mm (1/32”) to 40mm. Thread taps are of different types; these are used using special tools. The forms of thread taps include plug, taper and bottoming, and they differ based on the need and purpose.The form of the thread tap must be selected in accordance with the equipment used to facilitate efficient operations. Thread taps are tools for cutting internal and external threads and making internal diameter threads. Thread taps are basically the same as threading cutters, when we talk about their basic shapes, look and working principle. But they have the differences in cutting mechanism and threading characteristics.
There are different types of thread taps that are used for a variety of reasons and purposes
1. Straight Flute Taps (Hand Taps)
Straight flute taps are very similar to plug taps but they also have straight flutes instead of spiral flutes. The straight flute tap has a very shallow taper per millimeter so that it can be used with deep threads without any risk of breaking off when tapping into difficult materials. Straight flute tap has a single start thread at right angles to the shank. This type can be used in blind holes or in ways that intersect hole walls at an included angle within 90 degree range. Straight flute taps are available in the two main configurations, tapered and plug. The tapered variety has been designed for use with turned work, where a shoulder is provided at the bottom of the hole and this allows for a quicker transition from turning to tapping than the plug design.
2. Spiral Point Taps (Bull Nose Taps)
The most popular threading tools kit taps are spiral point taps, or thread mills. Spiral point taps have a spiral flute which gives the tap its cutting action, rather than a solid shank. Spiral point taps range from 1 mm to 6 mm in diameter, and are available in both right hand and left hand threads. Note: A special left hand thread is when a clockwise turning motion (as viewed from the top of the threaded insert) tightens the part as you turn – but if you were to turn the part counter-clockwise, it would loosen. When threading tools kit a hole for the mounting of a pipe or engine, it's important to remember that the thread should be on the side of the flat of the threads. If you allow them to be in any other spot, it will cause a skewed hole and make it hard to install.
3. Spiral Flute Taps (Gun Taps)
Spiral flute taps: ( Gun Taps) are a class of taps that have a spiral at the cutting edge of the tap, rather than one or more flutes. These types of taps were popular back in the day for two reasons: First, they are capable of producing threads with tiny pitches (although this comes at a cost: accuracy). Second, they can generate much faster threading speeds. As they create the thread by "dragging" rather than "scoring," they are capable of generating full depth threads in a single pass.
Spiral flute taps are used either when a cylindrical hole must be reamed to a defined depth and spiral flutes increase the removal of chips helping reduce the load on the drill, or when a helical groove is to be cut in a workpiece. The angle of the taper, lead and pitch vary according to the diameter and depth of the hole and the length of thread desired. The spiral flutes are located by a spacing tool based on their pitch. Gun taps, which are similar in appearance to bottoming taps, are best suited for rough work.
4. Roll Form Taps (Thread Forming Taps)
Roll form taps (thread forming taps) are a very specific type of tap that is often misunderstood. In fact, there are many micro-mini threading and threading taps that have been misclassified as roll form taps, when they are most definitely not. A roll form tap is something entirely different. Volkel has many types of thread tap that is used to cut a tap hole in soft materials. They generally enter the hole without difficulty and are used to cut threads in soft or deformed metals. Roll form taps are designed for use in soft materials such as aluminum, magnesium and copper.
