The OSG Threading Tap Metric A-LT-Spiral Flute is a precision right-hand tap designed for clean, reliable metric threads in blind holes. Built for demanding metalworking environments, it delivers consistent performance from start to finish on M4 x 0.7 applications.

• Tool Type: Threading tap for internal, blind-hole threads with metric sizing (M4 x 0.7) and a right-hand cut for standard assembly directions.
• Material: Powder metal body combines high strength with toughness to resist wear during deep tapping.
• Coating: TiCN coating enhances hardness and wear resistance while reducing friction for smoother cutting and longer tool life.
• Flute Design: LT (Long Taper) spiral flute promotes excellent chip evacuation, helping prevent clogging in deep blind holes and improving thread quality.
• Application: Optimized for precise threading in blind-hole configurations, including high-speed machining and challenging materials where dependable performance is essential.
• Orientation: Right-hand threading aligns with common assembly practices, ensuring straightforward use in standard production workflows.

The combination of a powder-metal backbone, TiCN coating, and a long-taper spiral flute translates into steadier starts, reduced tool drag, and longer longevity even under demanding tapping cycles. This tap is designed to deliver clean, accurate M4 x 0.7 threads in blind holes, helping to minimize rework and ensure consistent part quality across manufacturing runs. For best results, pair with appropriate cutting fluid and controlled speeds to maximize chip evacuation and surface finish, while protecting the tool through repeated cycles in high-speed applications.
