ANXCD5USHPM Hard Material Spiral Flute Tap UNC 5USH已售出0個A French-brand spiral flute tap built from powder-metallurgy HSS, the UNC 5USH, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 2 sizes (thread dia 1, pitch 13, thread length 2.5mm, overall length 85mm, shank dia 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, cast iron, non-ferrous metals like aluminium and copper, workpiece hardness up to HRC45. French brand, consistent quality.

Product Overview: Powder Metallurgy Hard Material Spiral Flute Tap UNC – 5USH 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 blind hole tapping accuracy and tool durability.
- Hard Material Spiral Flute UNC Blind Hole Dedicated Design: Features a UNC spiral flute tap design specifically optimized for high-hardness carbon steel, alloy steel, and cast iron — pulling chips upward and out of the hole, recommended for UNC blind hole tapping of high-hardness materials, effectively resolving chip accumulation at the hole bottom to ensure smooth UNC blind hole tapping and thread accuracy.
- HSS-PM Powder Metallurgy Premium Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), with maximum machining hardness up to HRC45 — delivering extremely uniform carbide distribution, outstanding toughness, and wear resistance, recommended for long-duration stable UNC spiral blind hole tapping of high-hardness difficult-to-machine materials, 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 UNC spiral tapping of high-hardness carbon steel, cast iron, and non-ferrous metals, effectively extending tool change intervals.
- Precise Specification Dedicated Coverage: Available in thread diameter 1 inch and pitch 13 TPI across 2 specifications — recommended as the dedicated high-performance tool for 1-inch UNC high-hardness blind hole tapping, addressing specific large-diameter North American specification high-hardness workpiece blind hole tapping requirements.
【Machining Applications & Uses】
- Primary Use: High-hardness material 1-inch UNC blind hole spiral tapping, hardened steel and high-hardness cast iron precision UNC blind hole thread forming, and NC machining center large-diameter UNC high-hardness automatic blind hole tapping.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC45, where HSS-PM combined with TiN coating delivers outstanding high-hardness UNC blind hole tapping wear resistance performance, representing the core advantage scenario for this series.
- K-Class (Cast Iron): High-hardness cast iron and gray iron — the spiral flute design effectively evacuates powdery chips, while the TiN coating provides outstanding wear-resistant UNC 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 UNC blind hole chip evacuation, preventing built-up edge from affecting thread quality.
