Product Overview: HSS Spiral Flute Pipe Tap PS – 5PSS 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 PS old-style parallel pipe thread spiral tapping accuracy and multi-material versatility.
- PS Old-Style Parallel Pipe Thread Spiral Flute Blind Hole Design: Features a spiral flute tap design that pulls chips upward and out of the hole — recommended for PS (old-style short thread parallel pipe thread) blind hole tapping operations, effectively resolving chip accumulation issues during pipe thread machining and ensuring parallel pipe thread profile accuracy, providing smoother chip evacuation in blind hole applications compared to the straight flute version (5PS).
- 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 PS spiral pipe thread tapping of carbon steel, stainless steel, and cast iron across various material conditions.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous PS pipe thread spiral tapping across various materials, effectively extending tool change intervals and suppressing cutting heat accumulation.
- Broad Material Compatibility: Covers carbon steel, alloy steel, stainless steel, cast iron, and non-ferrous metals — recommended as the standard configuration tool for cross-material general-purpose PS pipe thread spiral blind hole tapping applications.
- 8 PS Specification Precise Coverage: Available in thread diameter 1–3 inches and pitch 14–28 TPI across 8 specifications — recommended as the high-performance stock tool for PS pipe thread spiral tapping across various materials, covering common old-style pipe equipment and Japanese standard pipe fitting PS blind hole pipe thread requirements.
【Machining Applications & Uses】
- Primary Use: PS old-style parallel pipe thread spiral blind hole precision tapping, old-style pipe equipment maintenance and retrofitting blind hole thread forming, and stainless steel and cast iron pipe component PS blind hole pipe thread machining.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC30, where HSS-EX combined with TiN coating delivers stable PS spiral blind hole pipe thread tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel pipe fittings — the spiral flute design effectively manages continuous chip upward evacuation, while the HSS-EX substrate suppresses work hardening, recommended for use with appropriate cutting fluid.
- K-Class (Cast Iron): Cast iron and gray iron pipe components — the TiN coating provides outstanding wear-resistant PS pipe thread tapping tool life.
- N-Class (Non-Ferrous Metals): Aluminum alloys, copper pipe fittings, and other non-ferrous metals — the spiral flute design ensures smooth chip evacuation, preventing built-up edge from affecting PS pipe thread quality.
