The OSG Threading Tap BSW A-Spiral Flute is a high-performance tool designed for cutting British Standard Whitworth threads in blind holes. Built for machinists and fabricators who demand precise, durable internal threads, this TiCN-coated powder metal tap delivers reliable results in challenging blind-hole applications.
- Thread Type: BSW (British Standard Whitworth) right-hand thread, DIN2184-1 compliant for consistent, standard-compatible taps
- A-Spiral Flute Design: Optimizes chip evacuation in blind holes to reduce sawing resistance and improve finish
- Material: Powder metal construction for enhanced hardness, wear resistance, and long tool life
- Coating: TiCN coating lowers friction and increases hardness, enabling higher cutting speeds and better heat resistance
- Hole Type: Specifically engineered for blind holes, helping maintain thread quality when the hole does not traverse the workpiece
- Size: 7/16 x 14 (major diameter 7/16 inch with 14 threads per inch) for precise, standard BSW threading
- Direction: Right-hand tapping—suitable for the majority of standard internal-threading tasks
- DIN Standard: DIN 2184-1 specification alignment to ensure compatibility with common tapping practices
This tap is built to deliver clean, accurate threads while withstanding demanding production environments. The TiCN-coated powder metal body provides durable performance across multiple jobs, and the spiral flute design helps keep chips moving away from the cutting edge—reducing the risk of binding in tight blind holes. Whether you’re building assemblies, repairing worn threads, or performing routine maintenance, this tap helps you achieve dependable results with fewer interruptions and longer tool life.
