ANXCD5BFSYatora General Purpose Spiral Flute Tap UNF 5BFS已售出0個Crafted in HSS-EX, the UNF 5BFS is a high-quality French-brand spiral flute tap, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 34 sizes (thread dia 1~9, pitch 12~64, thread length 2.5mm, overall length 42~125mm, shank dia 3~20mm). 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 HRC40. French brand, consistent quality.

Product Overview: HSS Tiger General-Purpose Spiral Flute Tap UNF – 5BFS 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 blind hole tapping accuracy, multi-material versatility, and tool consistency.
- Tiger General-Purpose UNF Fine Thread Spiral Flute Blind Hole Design: Features a Tiger (TIGER) general-purpose spiral flute tap geometry that pulls chips upward and out of the hole — optimized for versatility across multiple materials, recommended for UNF fine thread blind hole tapping of carbon steel, stainless steel, cast iron, and non-ferrous metals, where the fine thread design provides higher thread strength and locking reliability compared to UNC coarse threads.
- HSS-EX Ultra-High Performance Substrate: Manufactured with HSS-EX ultra-high performance high-speed steel, with maximum machining hardness up to HRC40 — delivering superior hardness, toughness, and wear resistance compared to standard HSS and HSS-CO, recommended for high-demand applications requiring long-duration stable UNF fine thread blind hole spiral tapping.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous UNF fine thread spiral blind hole tapping across various materials, effectively extending tool change intervals and suppressing cutting heat accumulation.
- 34 UNF Specification Ultra-Wide Coverage: Available in thread diameter 1–9 inches and pitch 12–64 TPI across 34 specifications — recommended as the most comprehensive UNF fine thread blind hole spiral tapping stock tool for factories and machining centers, covering all types of blind hole tapping needs for common North American fine thread specification workpieces.
【Machining Applications & Uses】
- Primary Use: UNF fine thread multi-material general-purpose blind hole spiral tapping, NC machining center UNF high-efficiency automatic blind hole tapping, and North American fine thread specification cross-material UNF blind hole thread forming.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC40, where HSS-EX 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 Tiger general-purpose spiral geometry effectively manages continuous chip upward evacuation, combined with HSS-EX 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.
