Our preferred supplier partners that offer a comprehensive range of Form taps include Balax, Dormer, Emuge, North American Tool & Sandvik Coromant. This, combined with the newest coatings, guarantees a very long tool life in most applications. Tap designs have changed considerably in that time. Ideal for Non-Lead Screw Tappers: the ability to form their own lead makes Form taps especially well suited for machines without lead screws.Ĭold forming technology has been used to produce threads for more than 100 years.Form taps can be operated at higher speeds and feeds than conventional taps. More Efficient Production: longer tap life, less tap breakage, and faster tapping speeds combine to reduce cycle time and machine downtime.Longer Tap Life: forming taps can last 3 to 20 times longer than cutting taps because they have no cutting edge to dull.Since the metal’s structure is cold worked along the thread profile, the threads produced are generally stronger and have a smooth, burnished surface finish. Stronger Taps: the absence of chips eliminates the need for flutes, resulting in a solid, stronger tap.Because no metal is cut away, the possibility of producing oversized threads is greatly reduced. Better Thread Gaging: forming taps rearrange the metal in the hole to create the thread.This is especially true for materials that work-harden such as steel and stainless steel. Stronger Threads: the grain flow of formed threads follows the contour of the thread, resulting in greater thread strength.Making threads without chips produces excellent thread surface quality, eliminates the risk of poor threads due to axial “mis-cutting”, increases static and dynamic strength of threads and allows elevated tapping speeds. Chip-less Tapping: since threads are formed and not cut, there are no chips to interfere with the tapping process or cause chip-removal problems in blind holes.However, suitable materials react to form tapping in different ways. Tapping via form tapping is appropriate for materials with tensile strength less than 1,200 N/mm 2 and fracture strain of 5 percent or less.Īs a rule of thumb, if a continuous chip is created when drilling, then the material is likely malleable enough and a good candidate for form tapping the threads. This larger hole is generated to allow room for the material to flow to create the minor diameter of the thread.įorm tapping is typically used in steels, stainless steels, light metal alloys and non-ferrous materials. One thing to really keep in mind is that form tapping requires a larger drill than a typical drill size for a cut tap. ![]() Roll form tapping has several benefits over cut tapping such as faster cutting speeds, stronger threads, no chips generated, stronger tap and longer tool life. Form tapping, also known as Roll Form tapping, is typically used in applications where traditional cut tapping is unsuitable. ![]()
