In fact, according to the most recent 2017 USCTI Data, over 25% of the US Market uses our form taps for their applications. Jarvis can optimize Jarflo forming tap designs utilizing variations in the number of lobes and lube grooves, variable cutdown lengths, and controlled minor diameters to maximize productivity and provide the lowest cost-per-hole. This feature displaces material evenly resulting in reduced torque requirements. They are also manufactured with the crest location in the cutdown section in perfect lead with the crest location in the full diameter. Jarflo forming taps are produced with ground radius crests designed to reduce torque requirements by as much as 50%. Our innovative designs are used for a wide variety if applications including: Jarflo is the premier name in roll form tapping. Because no metal is cut away, the possibility of producing oversized threads is greatly reduced. 1 language Read Edit View history Schematic of a machine tap Below is a comprehensive drill and tap size chart for all drills and taps, imperial and metric, up to 36. Stronger threads: The grain flow of formed threads – as a result of form tapping – follows the contour of the thread resulting in greater thread strength.īetter thread gaging: Forming taps rearranges the metal in the hole to create the thread. Longer tap life: Jarvis’ industry-leading forming taps last 3 to 20 times longer than cutting taps because they have no cutting edge to dull. This leads to cost savings and greater returns, which in the end equals a stronger hold and a bolstered bottom line. This enables cleaner holes with improved surface finish. Thus, the absence of chips eliminates the need for flutes, resulting in a solid, stronger tap for your application.Ĭhipless tapping: Since the thread is formed and not cut, there are no chips to interfere with the tapping process or to cause chip-removal problems in blind holes. Our company utilizes the latest technology and equipment to provide our customers world. Stronger taps: The absence of cutting material due to the use of forming taps eliminates chip residue. UPMOLD is a full-service injection molding molds builder specializes in the tooling design, engineering support, molds building and qualifying of plastic injection molds, UPMOLD operates with plastic injection presses ranging from 45T to 600T operating 24/6. Some of the benefits of form tapping include: In fact, there are many applications, which now specify Jarvis’ crest radius because of the extra strength they provide. Our rounded shoulders can dramatically increase tap life and create much stronger threads. The crest radius provides an edge prep for forming taps. But Jarvis ground crest radius has significant advantage in a wide variety of applications. This truncated thread form works the best in some applications. Thread percentage : (77 thread is what you want to use) A 100 thread is 3/4 qtr, or (6/8 th ), of the full 60° triangle which is the maximum allowed height of a full thread, the 'V' shape, including flats. Traditionally, taps are produced with crest flats. NOTE: The tap drill size of a hole that will be cold form tapped is usually bigger than it cutting tap counterpart. Third Party Inspection can be performed on request at buyer’s care and expense.You will not find any forming taps (Jarflo’s) that work as well as ours! Jarvis Cutting Tools has the ability to grind either a crest flat or a crest radius. This depends on the size and pitch of the thread and the material threaded.
