ANXCD5EDSpiral Flute Tap 15° German EMUGE Metric 5ED已售出0個A German-brand spiral flute tap built from HSS-E, the 15 5ED, ideal for tapping blind (non-through) holes — its spiral flutes pull chips back toward the shank, keeping the hole bottom clear. Available in 5 sizes (thread dia 5~12, pitch 0.8~1.75, thread length 12.5~30mm, overall length 70~110mm, shank dia 5.5~8.5mm). A TiN coating adds a hard golden film for better wear and anti-galling, extending tool life. Suitable for machining carbon and alloy steel, stainless steel, non-ferrous metals like aluminium and copper, workpiece hardness up to HRC40. German brand, consistent quality.

Product Overview: HSS Spiral Flute Tap 15° German-Made Metric – 5ED Series
【Product Features & Why We Recommend It】
- German Brand Premium Quality: Originating from a professional German cutting tool brand with rigorous quality control — recommended for precision machining users with the highest demands on metric spiral blind hole tapping accuracy and tool consistency.
- 15° Small Helix Angle Stable Design: Features a 15° small helix angle design — providing higher cutting edge rigidity and tool body strength compared to 45° large helix angle taps, recommended for blind hole tapping of harder or short-chip materials such as carbon steel and alloy steel, maintaining more stable tapping torque and thread accuracy under higher cutting resistance conditions.
- HSS-E Cobalt High-Performance Substrate: Manufactured with cobalt high-speed steel (HSS-E), with maximum machining hardness up to HRC40 — delivering superior red hardness and wear resistance compared to standard HSS, recommended for long-duration stable spiral blind hole tapping of carbon steel, stainless steel, and non-ferrous metals.
- TiN Coating Enhancement: The surface is treated with TiN coating, providing good wear resistance and heat resistance — combined with the outstanding characteristics of the HSS-E substrate, recommended for continuous blind hole tapping across various materials, effectively extending tool change intervals.
- German Manufacturing Precision Guarantee: German manufacturing precision and quality control — recommended for precision blind hole tapping applications with strict requirements on thread tolerance grades and fit accuracy, ensuring consistent thread dimensional accuracy across every tap.
- 5 Metric Specification Precise Coverage: Available in thread diameter 5–12mm and pitch 0.8–1.75mm across 5 specifications — recommended as the German quality stock tool for steel material precision metric blind hole spiral tapping.
【Machining Applications & Uses】
- Primary Use: Carbon steel and alloy steel metric precision blind hole spiral tapping, stainless steel and non-ferrous metal blind hole thread forming, and NC machining center high-quality automatic blind hole tapping.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — recommended for hardness below HRC40, where the 15° helix angle provides high cutting edge rigidity combined with HSS-E substrate and TiN coating, representing the ideal application scenario for this series and delivering stable blind hole tapping performance in higher-hardness steel materials.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the cobalt content of HSS-E combined with TiN coating effectively suppresses cutting heat accumulation, recommended for use with appropriate cutting fluid.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the 15° spiral design ensures stable blind hole chip evacuation, preventing built-up edge from affecting thread quality.
