ANVCD5AFPShort Thread Long Chip Spiral Point Tap UNF 5AFPSold0pcsThe UNF 5AFP is a French-brand spiral point tap made of HSS-EX, ideal for tapping through holes — its spiral point pushes chips forward for fast, clean threading. Available in 14 sizes (thread dia 1~5, pitch 20~80, thread length 3mm, overall length 36~85mm, shank dia 3~9mm). A TiN coating adds a hard golden film for better wear and anti-galling, extending tool life. Suitable for machining carbon and alloy steel, stainless steel, non-ferrous metals like aluminium and copper, workpiece hardness up to HRC30. French brand, consistent quality.

Product Overview: HSS Short Thread Long-Chip Material Spiral Point Tap UNF – 5AFP Series
【Product Features & Why We Recommend It】
- French Brand Professional Quality: Originating from a professional French cutting tool brand with rigorous quality control — recommended for users with high demands on UNF fine thread multi-material tapping accuracy and tool consistency.
- Short Thread Long-Chip Material UNF Fine Thread Dedicated Geometry: Features a spiral point tap geometry specifically optimized for the long-chip cutting characteristics of aluminum alloys and copper materials, as well as the continuous chip formation of stainless steel — recommended for applications prone to built-up edge, chip wrapping, and adhesion issues during non-ferrous metal and stainless steel UNF tapping, effectively improving fine thread tapping smoothness and thread quality.
- HSS-EX Ultra-High Performance Substrate: Manufactured with HSS-EX ultra-high performance high-speed steel, delivering superior hardness, toughness, and wear resistance compared to standard HSS and HSS-CO — recommended for long-duration stable UNF fine thread tapping of carbon steel, stainless steel, and non-ferrous metals.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance — combined with the short thread geometry design to effectively suppress built-up edge adhesion during non-ferrous metal machining, recommended for continuous UNF fine thread tapping across various materials to extend tool service life.
- Spiral Point Through-Hole Design: Features a spiral point tap design that pushes chips forward and out of the hole — recommended for multi-material UNF through-hole tapping operations, effectively managing long chip evacuation to ensure smooth fine thread tapping and thread accuracy.
- 14 UNF Specification Precise Coverage: Available in thread diameter 1–5 inches and pitch 20–80 TPI across 14 specifications — recommended as the dedicated high-performance stock tool for UNF fine thread multi-material through-hole tapping.
【Machining Applications & Uses】
- Primary Use: Multi-material UNF fine thread through-hole precision tapping, precision machinery UNF fine thread forming, and NC machining center UNF multi-material automatic tapping.
- Recommended Work Materials:
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the short thread long-chip material dedicated geometry combined with HSS-EX substrate and TiN coating effectively addresses long chip management, built-up edge, and adhesion challenges, representing the core recommended application scenario for this series, recommended for use with appropriate cutting fluid.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the short thread geometry combined with TiN coating effectively suppresses continuous chip formation and adhesion, recommended for use with appropriate cutting fluid to ensure UNF fine thread quality.
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC30, where HSS-EX combined with TiN coating delivers stable UNF fine thread tapping performance.
