ANXCD5FSPM General Purpose Spiral Flute Tap UNF 5FS已售出0個A French-brand spiral flute tap built from powder-metallurgy HSS, the UNF 5FS, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 28 sizes (thread dia 1~9, pitch 16~64, thread length 2.5mm, overall length 42~105mm, shank dia 3~14mm). 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, cast iron, non-ferrous metals like aluminium and copper, workpiece hardness up to HRC35. French brand, consistent quality.

Product Overview: Powder Metallurgy General-Purpose Spiral Flute Tap UNF – 5FS 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 American standard fine thread spiral flute tap accuracy and multi-material versatility.
- Spiral Flute UNF Fine Thread Blind Hole Dedicated Design: Features a spiral flute tap design that pulls chips upward and out of the hole — recommended for UNF fine thread blind hole tapping operations, effectively resolving the chip accumulation issue at the hole bottom, ensuring smooth UNF fine thread blind hole tapping and thread accuracy, where the fine thread design also provides higher thread strength and locking reliability compared to UNC coarse threads.
- HSS-PM Powder Metallurgy High-Performance Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), delivering more uniform carbide distribution, higher toughness, and superior wear resistance compared to standard HSS and HSS-CO — recommended for long-duration stable UNF fine thread blind hole tapping across various materials.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous UNF spiral tapping of carbon steel, alloy steel, stainless steel, cast iron, and non-ferrous metals, effectively extending tool change intervals.
- 28 UNF Specification Precise Coverage: Available in thread diameter 1–9 inches and pitch 16–64 TPI across 28 specifications — recommended as the dedicated high-performance stock tool for UNF fine thread blind hole tapping in factories and machining centers, covering common North American fine thread specification workpiece blind hole tapping requirements.
【Machining Applications & Uses】
- Primary Use: UNF fine thread blind hole multi-material spiral tapping, NC machining center UNF automatic blind hole tapping, and North American fine thread specification cross-material blind hole thread forming.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC35, where HSS-PM combined with TiN coating delivers stable and long-lasting UNF fine thread blind hole tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the spiral flute design effectively manages continuous chip upward evacuation, combined with HSS-PM substrate to suppress work hardening, recommended for use with appropriate cutting fluid.
- K-Class (Cast Iron): Cast iron and gray iron — the TiN coating provides outstanding wear-resistant UNF fine thread blind hole tapping tool life.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the spiral flute design ensures smooth UNF fine thread blind hole chip evacuation, preventing built-up edge from affecting thread quality.
