ANXCD5HUSHigh Speed PM Spiral Flute Tap UNC 5HUS已售出0個A French-brand spiral flute tap built from powder-metallurgy HSS, the UNC 5HUS, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 8 sizes (thread dia 1~5, pitch 13~40, thread length 2.5mm, overall length 44~85mm, 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, workpiece hardness up to HRC42. French brand, consistent quality.

Product Overview: High-Speed Powder Metallurgy Spiral Flute Tap UNC – 5HUS 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 high-hardness material UNC spiral flute tap accuracy and tool durability.
- High-Speed Spiral Flute UNC Blind Hole Design: Features a spiral flute tap design that pulls chips upward and out of the hole — recommended for UNC blind hole tapping of carbon steel and stainless steel, effectively resolving chip accumulation at the hole bottom to ensure smooth UNC blind hole tapping and thread accuracy in high-hardness materials.
- HSS-PM Powder Metallurgy High-Performance Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), with maximum machining hardness up to HRC42 — delivering extremely uniform carbide distribution, outstanding toughness, and wear resistance, recommended for long-duration stable high-speed UNC spiral blind hole tapping of carbon steel and stainless steel, providing superior tool life compared to standard HSS and HSS-CO.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous high-speed UNC spiral tapping of carbon steel and stainless steel, effectively extending tool change intervals and suppressing cutting heat accumulation.
- 8 UNC Specification Precise Coverage: Available in thread diameter 1–5 inches and pitch 13–40 TPI across 8 specifications — recommended as the dedicated high-performance stock tool for high-hardness material UNC blind hole tapping, covering common North American specification high-hardness workpiece blind hole tapping requirements.
【Machining Applications & Uses】
- Primary Use: High-hardness material UNC blind hole high-speed spiral tapping, NC machining center UNC high-efficiency automatic blind hole tapping, and precision UNC blind hole thread forming in carbon steel, alloy steel, and stainless steel.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC42, where HSS-PM combined with TiN coating delivers outstanding high-speed UNC blind hole tapping wear resistance performance, representing the ideal application scenario for this series.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the spiral flute design effectively manages continuous chip upward evacuation, while the HSS-PM powder metallurgy substrate suppresses work hardening, recommended for use with appropriate cutting fluid.
