The OSG Threading Tap UNF A-Spiral Flute is a high-precision tapping tool designed for UNF threads in blind holes. Built for professionals in metal fabrication and precision machining, it combines durability with reliable performance to deliver consistent, accurate threads.
- Thread type: UNF (Unified National Fine) for precise threading in blind holes.
- A-Spiral flute: Optimized flute geometry for efficient chip evacuation and reduced clogging in blind-hole applications.
- Material: Powder metal construction for enhanced durability and wear resistance.
- Coating: TiCN (Titanium Carbonitride) coating to increase hardness, lower friction, and improve cutting performance.
- Orientation: Right-hand threading for standard tapping operations.
- Size: 3/8 x 16 UNF, DIN2184-1 compliant for compatibility with common UNF specifications.
The TiCN coating and powder metal base work together to extend tool life, especially under high-speed machining conditions, while the A-Spiral flute design supports steady chip flow and reduces the risk of rework due to chip buildup. The DIN2184-1 compliance ensures predictable results with standard UNF blind-hole tapping, helping you achieve clean, accurate threads on the first pass. Ideal for metal parts where blind holes are required, this tap supports tighter tolerances and consistent performance across production runs.
