The OSG Metric A-Spiral Flute Threading Tap with HB Weldon shank is a precision tapping tool designed for reliable threading of metric blind holes. Ideal for professionals and shops that demand consistent, accurate threads in metal components.

• Flute Design: A-Spiral flute optimizes chip evacuation in blind holes, reducing buildup and improving tapping reliability.
• Size and Thread: Metric M5 x 0.8 threading specification for common metric applications and compatibility with standard fasteners.
• Material: Powder metal construction delivers strong wear resistance and enduring durability under demanding tapping operations.
• Coating: TiCN coating provides a harder, low-friction surface to minimize wear and extend tool life.
• Shank Style: HB Weldon shank offers stable drive and precise alignment, enhancing concentricity during tapping.
• Handedness: Right-hand thread, suitable for typical clockwise tapping processes.
• DIN Standard: DIN 371/1835 compliance ensures broad compatibility with industry-standard blind-hole tapping tasks.

This tap excels in precision work where blind-hole geometry is common—such as housings, enclosures, and components using metric blind threads. The combination of a robust powder-metal body, TiCN-coated cutting edges, and a secure Weldon shank translates to smoother hole preparation, reduced rework, and repeatable, high-quality threads across production runs.
