Product Overview: HSS Tiger Stainless Steel Spiral Point Tap UNF – 5SFP 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 stainless steel fine thread tapping accuracy and tool durability.
• UNF Stainless Steel Fine Thread Dedicated Optimized Design: Features a spiral point tap geometry specifically optimized for the difficult-to-machine characteristics of stainless steel — including high toughness, susceptibility to work hardening, and continuous chip formation — recommended for precision UNF stainless steel fine thread machining applications where standard UNF taps are prone to tooth chipping due to adhesion or work hardening, serving as the dedicated solution for UNF stainless steel fine thread tapping.
• 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 difficult-to-machine materials such as stainless steel.
• Black Oxide Surface Treatment: The surface is treated with black oxide (Steam Oxide) finishing, providing good lubricity and anti-adhesion characteristics — more effectively reducing friction between chips and the tool compared to uncoated tools, recommended for suppressing built-up edge and adhesion issues during UNF stainless steel fine thread tapping to maintain fine thread quality and tapping stability.
• Spiral Point Through-Hole Design: Features a spiral point tap design that pushes chips forward and out of the hole — recommended for stainless steel UNF through-hole tapping operations, effectively managing continuous chip evacuation to ensure smooth fine thread tapping and thread accuracy.
• 6 UNF Specification Precise Coverage: Available in thread diameter 1–5 inches and pitch 20–36 TPI across 6 specifications — recommended as the dedicated high-performance stock tool for UNF stainless steel fine thread through-hole tapping, addressing precision machinery and North American specification stainless steel workpiece fine thread tapping requirements.

【Machining Applications & Uses】

• Primary Use: Stainless steel UNF fine thread through-hole precision tapping, North American specification precision stainless steel component fine thread forming, and NC machining center UNF stainless steel automatic tapping.
• Recommended Work Materials:
  • M-Class (Stainless Steel): SUS304, SUS316, SUS420, and other high-toughness stainless steel — the sole dedicated recommended application scenario for this series, where the UNF stainless steel fine thread dedicated geometry combined with HSS-EX substrate and black oxide surface treatment effectively addresses the unique UNF stainless steel fine thread tapping challenges of work hardening, continuous chip formation, and adhesion, recommended for use with appropriate cutting fluid.
