The OSG Threading Tap is a precision metric fine tapping tool designed for blind-hole applications. Built for machinists who demand clean, accurate threads in tight cavities, it delivers reliable performance with long tool life.

• Size and standard: Metric fine thread, M9 x 1, optimized for DIN374 blind-hole tapping.
• Flute geometry: A-Spiral Flute for efficient chip evacuation in restricted holes and at higher speeds.
• FORM E geometry: Form-cut design that promotes consistent thread quality and smooth cutting action.
• Material: Powder Metal substrate offering enhanced wear resistance and toughness for demanding use.
• Coating: TiCN coating increases surface hardness and reduces friction, extending tool life.
• Cutting direction: Right-Hand threading for standard metric applications and common machining setups.
• Application: Specifically engineered for tapping blind holes, delivering reliable threads when access is limited.

Equipped with FORM E geometry, TiCN-coated powder-metal construction, and an optimized A-Spiral flute, this tap delivers durable performance and precise thread formation in challenging blind-hole tasks. The combination reduces wear, improves finish quality, and minimizes downtime, making it well-suited for automotive, aerospace, and precision manufacturing environments where tight-access threading is routine. Pair it with compatible tapping machines or hand-tapping operations to achieve reproducible M9 x 1 threads with minimal chatter and consistent results.
