WESTport manufactures Special Spiral Flute Tandem Taps for manufacturers requiring maximum thread accuracy, improved productivity, and exceptional tool performance in demanding blind-hole applications. Tandem taps combine roughing and finishing operations into a single tool, allowing threads to be produced efficiently while maintaining excellent dimensional consistency. When paired with a spiral flute design, chips are continuously lifted out of the hole, reducing chip packing and improving machining reliability in applications where conventional taps may struggle. Spiral Flute Tandems – Special are part of WESTport's custom tap offering for specialized manufacturing requirements.
Every WESTport Special Spiral Flute Tandem Tap is manufactured to customer specifications using premium High-Speed Steel (HSS), cobalt, powdered metal, or carbide materials selected for the workpiece and production environment. Precision grinding ensures accurate thread geometry, smooth cutting action, and excellent repeatability from the first part to the last. Our engineering team can manufacture tandem taps in Unified, Metric, ACME, pipe thread, and many proprietary thread forms while accommodating custom diameters, pitches, thread lengths, chamfers, coatings, and special design features.
The tandem design allows the leading section of the tap to progressively prepare the thread while the trailing section finishes the thread to its final size and form. Combined with spiral flute geometry, this results in efficient chip evacuation from blind holes, improved surface finish, and reduced cutting loads. These advantages help minimize tool wear, improve cycle times, and reduce the likelihood of broken taps in production environments.
WESTport Special Spiral Flute Tandem Taps are widely used in aerospace, automotive, hydraulic, medical, energy, and general industrial manufacturing where precision internal threads must be produced consistently over long production runs. Whether you require prototype tooling or high-volume production quantities, WESTport works closely with your engineering and manufacturing teams to develop a custom solution that maximizes machining performance and tool life.
Since 1989, WESTport has supplied precision quality assurance products and custom manufacturing solutions to manufacturers throughout North America and around the world. Our commitment to quality, responsive customer service, and technical expertise has made WESTport a trusted source for specialty tapping solutions.

Technical Information
Spiral Flute Tandem Taps combine the productivity advantages of a tandem tap with the chip evacuation benefits of a spiral flute design. The helical flutes direct chips upward and out of blind holes while the tandem geometry progressively roughs and finishes the thread in one operation. WESTport can customize thread form, flute geometry, chamfer style, coatings, overall length, and other design features to match your machining requirements and maximize tool performance.
