WESTport Forming Taps are designed to produce precision internal threads through a chipless forming process rather than conventional cutting. Instead of removing material, the tap displaces the workpiece material to form the thread profile. This process creates stronger threads with excellent surface finishes while eliminating chip generation, making Forming Taps an outstanding choice for high-production manufacturing and blind-hole applications. WESTport offers Forming Taps in both left-hand and right-hand configurations to meet a wide range of production requirements.
Because no chips are produced during tapping, Forming Taps simplify machining operations where chip evacuation is difficult or impossible. This is especially beneficial in blind holes, where chips produced by conventional cutting taps can accumulate, damage threads, or lead to premature tap failure. The lobed thread-forming geometry contacts the workpiece at multiple points, allowing the material to flow into the finished thread shape while maintaining excellent dimensional consistency. This design supports faster tapping speeds, increased production efficiency, and highly repeatable thread quality.
WESTport manufactures Forming Taps using premium High-Speed Steel (HSS), cobalt, powdered metal, and other high-performance tool materials selected to match the application. Every tap is precision manufactured to provide accurate thread geometry, excellent wear resistance, and long service life. Standard sizes are available, while custom Forming Taps can be produced for special diameters, pitches, thread lengths, left-hand or right-hand configurations, and customer-specific requirements.
Forming Taps perform exceptionally well in ductile materials such as aluminum, brass, copper, low-carbon steel, stainless steel, and many other materials that possess sufficient ductility for thread forming. By preserving the material's grain flow rather than cutting through it, the resulting threads often exhibit improved strength and fatigue resistance compared to conventionally cut threads.
Whether your operation involves prototype work, automated CNC machining, or high-volume production, WESTport Forming Taps provide a dependable solution for manufacturers seeking improved productivity, longer tool life, and consistent thread quality. Since 1989, WESTport has supplied precision quality assurance products and custom manufacturing solutions to manufacturers throughout North America and around the world.

Technical Information
Forming Taps utilize a lobed thread profile that plastically displaces material rather than removing it. Because the process is chipless, proper tap drill size and adequate lubrication are essential to achieving optimum thread quality and maximizing tool life. Forming taps are best suited for ductile materials capable of flowing during the thread-forming process. WESTport offers both standard and custom Forming Taps engineered to match specific production requirements.
