Product Overview: HSS Oversize Tap Spiral Flute UNC – 5OUS 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 UNC thread repair and oversize blind hole tapping accuracy and multi-material versatility.
- UNC Oversize Tap Spiral Flute Blind Hole Repair Design: Features a spiral flute oversize tap geometry that pulls chips upward and out of the hole — with a thread diameter specification larger than standard taps, recommended for UNC blind hole thread repair and oversize machining after thread stripping, chipping, or damage, effectively restoring North American specification workpiece threaded hole functionality, serving as an essential tool for on-site maintenance and equipment repair.
- HSS-EX Ultra-High Performance Substrate: Manufactured with HSS-EX ultra-high performance high-speed steel, with maximum machining hardness up to HRC45 — delivering superior hardness, toughness, and wear resistance compared to standard HSS and HSS-CO, recommended for long-duration stable UNC spiral blind hole repair tapping across various materials.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous UNC oversize spiral repair tapping of carbon steel, stainless steel, cast iron, and non-ferrous metals, effectively extending tool change intervals.
- 66 UNC Specification Wide Coverage: Available in thread diameter 1–5 inches and pitch 13–56 TPI across 66 specifications — recommended as the most comprehensive UNC blind hole spiral oversize repair tapping stock tool for factories and maintenance centers, covering all types of thread repair needs for common North American specification workpieces.
【Machining Applications & Uses】
- Primary Use: UNC blind hole stripped thread repair and oversize tapping, North American specification damaged threaded hole functionality restoration, and on-site equipment maintenance UNC thread repair.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC45, where HSS-EX combined with TiN coating delivers stable UNC spiral oversize repair tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the spiral flute design effectively manages continuous chip upward evacuation, recommended for use with appropriate cutting fluid.
- K-Class (Cast Iron): Cast iron and gray iron — the TiN coating provides outstanding wear-resistant UNC repair tapping tool life.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the spiral flute design ensures smooth blind hole chip evacuation, preventing built-up edge from affecting UNC repair thread quality.
