![]() 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. ![]()
