The OSG Metric Spiral Flute Threading Tap is designed for machinists who need precise, durable threads in blind holes. Built from HSS-E with a steam oxide coating, this tap delivers consistent results for M7 x 1 threads in demanding production and prototype environments.

• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance, empowering reliable threading under load.
• Coating: Steam oxide finish reduces friction and improves wear resistance, extending tool life during high-speed threading.
• Flute Design: Spiral flute configuration promotes efficient chip evacuation, minimizing clogging in blind-hole applications.
• Thread Form: Metric M7 x 1 thread profile provides precise, standard-compliant threads for common assemblies.
• Application: Optimized for blind-hole tapping, delivering smooth entry, stable cutting, and consistent thread quality.
• Durability: Coated HSS-E construction maintains sharpness longer and withstands repeated use in challenging materials.

With this tap, you gain predictable thread engagement, reduced rework, and longer tool life in demanding environments. The spiral flute design minimizes chip buildup, promoting cleaner holes and faster cycle times. The combination of HSS-E and steam oxide coating delivers dependable performance for prototyping and production tasks, helping critical assemblies meet exacting tolerances every time.
