Product Overview: HSS Multi-Purpose Spiral Point Tap Imperial – 5GWP 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 standard demands on imperial thread tapping cost-effectiveness and multi-material versatility.
- Multi-Purpose Imperial Versatile Design: Features a multi-purpose spiral point tap geometry — recommended for imperial through-hole tapping across multiple materials from carbon steel and alloy steel to non-ferrous metals, effectively addressing diverse daily British standard machining needs with a single tool to reduce stock tool variety and management costs, well-suited for flexible scheduling in mixed-specification machining environments.
- 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 imperial tapping in daily machining applications, providing superior tool life compared to standard HSS.
- Black Oxide Surface Treatment: The surface is treated with black oxide (Steam Oxide) finishing, providing good lubricity and anti-adhesion characteristics — recommended for imperial tapping of carbon steel and non-ferrous metals, effectively reducing friction between chips and the tool and preventing built-up edge formation.
- Spiral Point Through-Hole Design: Features a spiral point tap design that pushes chips forward and out of the hole — recommended for multi-material imperial through-hole tapping operations, ensuring smooth chip evacuation and thread accuracy.
- 13 Imperial Specification Precise Coverage: Available in thread diameter 1–9 inches and pitch 8–40 TPI across 13 specifications — recommended as the economical and practical stock tool for daily imperial through-hole tapping in factories and machining centers, covering common British standard imported equipment maintenance and imperial component tapping requirements.
【Machining Applications & Uses】
- Primary Use: Imperial multi-material through-hole daily tapping, carbon steel and alloy steel imperial thread forming, and non-ferrous metal imperial 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 black oxide treatment delivers stable daily imperial tapping performance.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the black oxide surface treatment effectively suppresses built-up edge adhesion, while the spiral point design ensures smooth chip evacuation, recommended for use with appropriate cutting fluid.
