Product Overview: Powder Metallurgy General-Purpose Spiral Flute Tap Metric – 5TR 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 metric spiral flute tap accuracy and multi-material versatility.
- Spiral Flute Blind Hole Dedicated Design: Features a spiral flute tap design that pulls chips upward and out of the hole — recommended for metric blind hole tapping operations, effectively resolving the chip accumulation issue at the hole bottom common with spiral point taps, ensuring smooth blind hole tapping and thread accuracy, making it the preferred tap type for blind hole applications.
- HSS-PM Powder Metallurgy High-Performance Substrate: Manufactured with powder metallurgy high-speed steel (HSS-PM), delivering more uniform carbide distribution, higher toughness, and superior wear resistance compared to standard HSS and HSS-CO — recommended for long-duration stable blind hole tapping across various materials.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — recommended for continuous spiral tapping of carbon steel, alloy steel, stainless steel, and cast iron, effectively extending tool change intervals.
- 99 Metric Specification Ultra-Wide Coverage: Available in thread diameter 1.4–30mm and pitch 0.3–3.5mm across 99 specifications — recommended as the most comprehensive metric blind hole tapping stock tool for factories and machining centers, covering all thread size requirements within a single series.
【Machining Applications & Uses】
- Primary Use: Metric blind hole multi-material spiral tapping, NC machining center high-efficiency automatic blind hole tapping, and cross-material standard metric blind hole thread forming.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC35, where HSS-PM combined with TiN coating delivers stable and long-lasting blind hole tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the spiral flute design effectively manages continuous chip upward evacuation, combined with HSS-PM substrate to suppress work hardening, recommended for use with appropriate cutting fluid.
- K-Class (Cast Iron): Cast iron and gray iron — the TiN coating provides outstanding wear-resistant 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 blind hole chip evacuation, preventing built-up edge from affecting thread quality.
