Long Series Special Taps

WESTport manufactures Special Long Series Taps in both left-hand and right-hand configurations for applications requiring greater thread reach than conventional machine taps. Designed with an extended threaded section and increased overall length, these taps provide reliable access to deep bores, recessed features, and difficult-to-machine components while maintaining excellent thread accuracy and cutting performance. When standard taps cannot reach the required thread depth or machining location, WESTport's Long Series Taps provide a dependable custom-engineered solution.

Every WESTport Long Series Tap is custom manufactured to your exact specifications using premium High-Speed Steel (HSS), cobalt, powdered metal, or carbide materials selected specifically for your workpiece material and machining requirements. Precision grinding produces highly accurate thread geometry, smooth cutting action, and exceptional dimensional repeatability. WESTport manufactures Long Series Taps for Unified, Metric, ACME, Pipe Thread, NPT, NPTF, BSP, and many specialty thread forms, with custom diameters, pitches, thread lengths, chamfer styles, shank configurations, and overall lengths available to match virtually any application.

The extended design allows machinists to produce precision internal threads in deep cavities, thick workpieces, hydraulic manifolds, valve bodies, castings, molds, and other components where additional thread reach is essential. WESTport engineers each tap to minimize deflection while maintaining proper strength and chip evacuation for the intended machining process. Optional premium coatings further improve wear resistance, reduce friction, and extend tool life during high-volume production or when machining difficult materials.

Long Series Taps are widely used throughout the aerospace, automotive, defense, energy, hydraulic, medical device, mold and die, and heavy equipment industries. Whether producing prototype components or supporting continuous production, manufacturers depend on these specialty taps to deliver consistent thread quality while reducing setup challenges and improving machining efficiency.

Since 1989, WESTport has supplied precision thread gages, custom taps, hardness testing equipment, metrology products, and ISO/IEC 17025 calibration services to manufacturers worldwide. Our experienced engineering team works directly with customers to develop custom thread-cutting solutions that improve productivity, reduce downtime, and consistently produce precision threads for demanding industrial applications.
