![]() ![]() ![]() Larger tools produce more friction and require more machine horsepower. When form tapping titanium, a lot of that heat penetrates the tool and causes premature failure.įorm taps are typically less than 3⁄4 ", or an M20, in diameter. Because forming doesn’t create chips, the heat must go into the tap or the material. During a tapping operation, heat enters the workpiece, tap and chips, he explained. “In addition to its high tensile strength and low ductility, titanium has very low thermal conductivity, meaning that it doesn’t absorb heat very well,” Gennuso said. ![]() Brittle materials, such as cast iron, do not flow well and cannot be form tapped. Material with a tensile strength of 160,000 psi and a maximum hardness of 36 HRC is about the limit for form tapping, although form taps for some materials up to 40 HRC are available.Ī range of metals can be form threaded, including aluminum, stainless steel, carbon steel, titanium and nickel. He estimates the ratio of cut taps to form taps used is about 100:1.įorm tapping requires a workpiece material that can actually flow to create the thread profile. But whether they call it form tapping, cold form tapping, thread forming, cold roll forming, roll forming, thread rolling, roll tapping or cold roll tapping, many metalworking professionals are unfamiliar with, according to Peter Gennuso, applications engineering supervisor for OSG Tap & Die Inc., Glendale Heights, Ill.Īl Zaitoon, marketing manager for YG-1 Tool Co., Vernon Hills, Ill., agreed that cut taps are more accepted and better understood. The process of displacing metal instead of cutting it is called many things. With that in mind, Jarvis’ exclusive tooling solutions have been continuously proven to reach far beyond the performance of the tools you are using now.Ĭontact us today to set up a free consultation and (if applicable) trial period to help cultivate the exact tool you need to achieve a competitive advantage.When the application is right, form tapping provides real production benefits. Standard catalog items can take you only part of the way why not experience an exclusive solution? It requires both you (the customer) and us (the supplier) to define the objective, test the options, measure the results, and implement the solution. Therefore, it requires work, discipline, and more work. In addition, our customers need a competitive advantage, and gaining an advantage in this competitive industry is not easy. Jarvis custom manufactures taps for all special and exotic requirements. Removed male center taps for shorter tap throw (as requested).Jarvis has the answer to maximizing tapping speed and optimizing cycle times.The premium A286 Jarhook tap is designed and produced with the combination of premium high speed steel substrate, the Titanium Carbo-Nitride (TiCN) surface treatment, and a free cutting geometry, which ultimately makes this product line the top choice for aerospace manufacturing companies looking for an A286 tap for their applicable fastener needs. Available in different configurations (spiral point, spiral flute, forming) for your application.Thus, this outperformed the competition at this speed by over 30%. In a controlled testing environment the 10-32 Jarhook A286 tap achieved an average tool life of 1,200 holes at a speed of 1,000 RPM in A286 6-point nuts. In fact, during extensive testing the Jarhook surpassed all of the competition in tool life and tapping speed. Our Jarhook tap is the best available tap for A286 fasteners. For this particular fastener, Jarvis has long been the purveyor of the Jarhook product line of taps. To bring to market superior cutting tools like the A286 Taps to bring out the most in any fastener application.įurtherly, since fastener manufacturers operate with very close profit margins, the taps used must be cost effective by generating long tool life and performing at a high rate, all at the lowest possible cost.įor instance, one such fastener that is of utmost importance when it comes to the tap is the A286 fastener. Lucky for you, that’s why Jarvis Cutting Tools exists. Tapping hardened steel / hard materials.A286 TAPS FASTENERS FOR AUTOMOTIVE, AEROSPACE AND GENERAL PURPOSE APPLICATIONS ALL DEMAND CONSISTENT HIGH QUALITY THREADS. ![]()
