OSG Metric Spiral Flute Threading Tap M22 x 2.5 is a precision tool designed for professionals who need reliable internal threads in blind holes. Built from HSS-E (high-speed steel with cobalt) and finished with a steam oxide coating, it delivers lasting durability and consistent cutting performance in demanding metalworking tasks.

• Thread size: Metric spiral-flute threading tap for blind-hole tapping, M22 x 2.5.
• Material: HSS‑E (high-speed steel with cobalt) for enhanced hardness and heat resistance.
• Coating: Steam oxide finish to reduce friction and improve wear resistance under cutting temps.
• Flute design: Spiral flutes engineered for efficient chip evacuation in blind holes, promoting smoother cuts.
• Application: Optimized for precise thread formation in blind-hole environments across metalworking tasks.
• Durability: Robust core and coating extend tool life through repeated tapping cycles.
• Brand & Technology: OSG’s advanced threading technology delivers consistent, high-quality results project after project.

The combination of cobalt-enhanced HSS-E, steam oxide coating, and a spiral flute geometry translates to reliable thread quality, reduced risk of tap binding or breakage in restricted environments, and longer tool life. This makes the OSG threading tap a dependable choice for critical internal threads in production or precision assemblies, helping you maintain tight tolerances and steady throughput.
