Learn more about Klarna
Description
The OSG Metric Spiral Flute Threading Tap in M5 x 0.8 is a purpose-built tool for machinists who need precise, durable blind-hole threading in metric sizes. With HSS-E cobalt and a Titanium Nitride coating, it blends toughness with smooth cutting performance for demanding metalworking tasks.
- Size: M5 x 0.8 thread for metric blind-hole threading
- Material & Coating: HSS‑E (high-speed steel with cobalt) with Titanium Nitride (TIN) coating for improved wear resistance
- Flute Design: Spiral flute engineered for efficient chip removal in blind holes
- Application: Suitable for precise tapping of blind holes, delivering consistent thread quality
- Manufacturer: Engineered with OSG’s advanced threading technology for reliable, repeatable results
This tap is designed to form clean, accurate threads while resisting wear in tougher materials. The combination of HSS‑E and TiN coating reduces friction and heat build-up, helping extend tool life and maintain dimensional accuracy across multiple taps. Its spiral-flute geometry aids chip evacuation, minimizing clogging and surface defects in blind-hole applications. Ideal for critical machining tasks where consistent thread fit and long-lasting performance matter—enabling smoother assembly, reduced rework, and higher productivity.
