The OSG BSF A-Spiral Flute Threading Tap is designed to cut British Standard Fine threads in blind holes with precision and reliability. Built for machinists, shop floors, and CNC operators, it delivers clean, accurate threads even in tight, non-through cavities.
- Thread Type: BSF (British Standard Fine), right-hand thread for standard tapping operations in blind holes.
- A-Spiral Flute Design: Optimized for chip evacuation in blind holes, reducing clogging and improving surface finish in restricted spaces.
- Material: Powder metal construction provides enhanced wear resistance and longevity under repeated tapping cycles.
- Coating: TiCN (Titanium Carbonitride) coating lowers friction and increases heat resistance for faster cutting speeds and longer tool life.
- Size & Standards: 1/2" x 16, DIN2184-1 compatibility for reliable performance in blind-hole applications.
In practice, this tap delivers durable performance in tough materials, maintains tight dimensional accuracy, and minimizes downtime through extended tool life. The combination of powder metal durability, TiCN coating, and the A-Spiral flute design helps you achieve consistent, high-quality BSF threads in challenging blind-hole assemblies, making it a dependable choice for precision threading tasks.
