ANXCD5CSCarbide Spiral Flute Tap Metric 5CSSold0pcsA French-brand spiral flute tap built from solid carbide, the 5CS, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 7 sizes (thread dia 3~12, pitch 0.5~1.75, thread length 7.5~30mm, overall length 46~82mm, shank dia 4~8.5mm). A TiCN coating boosts wear resistance and tool life. Suitable for machining carbon and alloy steel, cast iron, non-ferrous metals like aluminium and copper, workpiece hardness up to HRC55. French brand, consistent quality.

Product Overview: Tungsten Carbide Spiral Flute Tap Metric – 5CS 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 metric spiral blind hole tapping accuracy and ultimate tool durability.
- Tungsten Carbide Ultra-High Hardness Capability: Manufactured with tungsten carbide, with maximum machining hardness up to HRC55 — delivering superior wear resistance and cutting edge strength compared to any high-speed steel tap including HSS-PM, recommended for precision blind hole tapping of high-hardness materials where HSS taps struggle to perform adequately, serving as the ultimate solution for high-hardness material metric blind hole tapping.
- Spiral Flute Blind Hole Design: Features a spiral flute tap design that pulls chips upward and out of the hole — recommended for metric blind hole tapping of carbon steel, cast iron, and non-ferrous metals, effectively resolving chip accumulation at the hole bottom to ensure smooth blind hole tapping and thread accuracy in high-hardness materials.
- TiCN Advanced Coating Enhancement: The surface is treated with TiCN coating, providing higher hardness and wear resistance compared to standard TiN coating — combined with the outstanding characteristics of the tungsten carbide substrate, recommended for long-duration continuous blind hole tapping of high-hardness materials, effectively extending tool change intervals.
- 7 Metric Specification Precise Coverage: Available in thread diameter 3–12mm and pitch 0.5–1.75mm across 7 specifications — recommended as the top-performance stock tool for high-hardness material metric blind hole spiral tapping.
【Machining Applications & Uses】
- Primary Use: High-hardness material metric precision blind hole spiral tapping, hardened steel and high-hardness cast iron blind hole thread forming, and NC machining center high-hardness material automatic blind hole tapping.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC55, where the tungsten carbide substrate combined with TiCN coating delivers outstanding high-hardness 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 tungsten carbide high-hardness capability combined with spiral chip evacuation design 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, while the tungsten carbide substrate prevents built-up edge from affecting thread quality.
