ANXCD5EZSpiral Flute Tap 45° German EMUGE Metric 5EZ已售出0個Made of HSS-E, the 45 5EZ is a German-brand spiral flute tap, 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). 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 45° German-Made Metric – 5EZ 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.
- 45° Large Helix Angle Optimized Design: Features a 45° large helix angle design — providing stronger upward chip pulling capability compared to standard 30–35° helix angle taps, recommended for blind hole tapping of continuous-chip materials such as stainless steel and non-ferrous metals, ensuring smoother chip evacuation, effectively reducing tapping torque and preventing hole bottom chip accumulation to improve blind hole thread quality.
- 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.
- 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 precision metric blind hole spiral tapping, addressing common precision mechanical component metric blind hole tapping requirements.
【Machining Applications & Uses】
- Primary Use: Metric precision blind hole high-efficiency 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 45° helix angle combined with HSS-E substrate delivers stable blind hole tapping performance.
- M-Class (Stainless Steel): SUS304, SUS316, and other high-toughness stainless steel — the 45° large helix angle design effectively manages continuous chip upward evacuation, while the cobalt content of HSS-E suppresses work hardening, recommended for use with appropriate cutting fluid.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — the 45° large helix angle ensures smooth long chip evacuation in blind holes, preventing built-up edge from affecting thread quality.
