Product Overview: HSS Titanium Alloy Dedicated Spiral Flute Tap UNF – 5ZFS 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 titanium alloy and other difficult-to-machine material UNF fine thread spiral blind hole tapping accuracy and tool durability.
• Titanium Alloy UNF Fine Thread Blind Hole Dedicated Optimized Geometry: Features a UNF fine thread spiral flute tap geometry specifically optimized for the extreme difficult-to-machine characteristics of titanium alloys — including high strength, low thermal conductivity, and adhesion tendency — the spiral design pulls chips upward and out, recommended for titanium alloy UNF fine thread blind hole tapping operations, effectively managing chip evacuation and reducing cutting heat accumulation risk, while the fine thread design also provides higher thread strength and locking reliability compared to UNC coarse threads.
• HSS-PM Powder Metallurgy Premium Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), delivering extremely uniform carbide distribution, outstanding toughness, and wear resistance — recommended for long-duration stable UNF fine thread spiral blind hole tapping of extremely difficult-to-machine materials such as titanium alloys, providing superior tool life compared to standard HSS and HSS-CO.
• TiAlN Premium Coating Enhancement: The surface is treated with TiAlN coating, providing higher heat resistance and oxidation resistance compared to TiN and TiCN coatings — recommended for UNF fine thread spiral tapping of difficult-to-machine materials with high cutting temperatures such as titanium alloys, maintaining outstanding wear resistance performance even at elevated temperatures and significantly extending tool change intervals.
• 9 UNF Specification Precise Coverage: Available in thread diameter 1–9 inches and pitch 16–32 TPI across 9 specifications — recommended as the dedicated high-performance stock tool for titanium alloy and carbon steel/cast iron UNF fine thread blind hole spiral tapping, covering common North American fine thread specification difficult-to-machine workpiece blind hole tapping requirements.

【Machining Applications & Uses】

• Primary Use: Titanium alloy precision UNF fine thread blind hole spiral tapping, carbon steel, alloy steel, and cast iron UNF fine thread blind hole thread forming, and UNF difficult-to-machine material tapping operations in aerospace and precision machinery.
• Recommended Work Materials:
  • S-Class (Titanium Alloys): Ti-6Al-4V, pure titanium, and various titanium alloys — the most advantageous core recommended application scenario for this series, where the titanium alloy dedicated geometry combined with HSS-PM substrate and TiAlN coating effectively addresses the extreme challenges of high temperature, adhesion, and chemical reactions during titanium alloy UNF fine thread tapping, recommended for use with appropriate cutting fluid.
  • P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC35, where the TiAlN coating provides outstanding wear-resistant UNF fine thread blind hole tapping performance.
  • K-Class (Cast Iron): Cast iron and gray iron — the TiAlN coating's outstanding wear resistance characteristics provide excellent UNF fine thread blind hole tapping tool life.
