The OSG Metric Spiral Flute Threading Tap in M5 x 0.8 is engineered for precise blind-hole threading, delivering clean, consistent threads with durability you can rely on. Designed for professional machinists and shop floors, it balances performance and longevity in demanding metalworking tasks.

• Material: HSS-E (high-speed steel with cobalt) for exceptional hardness and wear resistance in demanding cutting conditions.
• Finish: Steam Oxide Coated Plus to enhance lubricity, reduce friction, and improve wear and corrosion resistance.
• Flute design: Spiral flute geometry optimized for efficient chip evacuation in blind holes, minimizing binding and heat buildup.
• Thread size: Metric M5 x 0.8 threading, suitable for standard metric fasteners and assemblies.
• Application: Ideal for blind-hole tapping across a range of ferrous and non-ferrous metals, delivering reliable start and steady depth control.
• Precision and durability: Consistent thread form with controlled chamfer and ground geometry to extend tool life and maintain tight tolerances.

This threading tap enables accurate, durable M5 x 0.8 threads in blind holes, helping you reduce thread defects and improve assembly reliability. The combination of HSS-E material and Steam Oxide coating delivers dependable performance under higher cutting temperatures, while the spiral flute design facilitates steady chip clearance, supporting faster, more controlled tapping and longer tool life. Whether you’re building precision components or performing routine maintenance, this tap provides the trusted efficiency and consistent results you expect from OSG.
