The OSG Threading Taps Rp (BSPP) A-Spiral Flute is a precision tapping tool designed for creating BSPP (British Standard Pipe Parallel) threads in blind holes. It’s ideal for machinists and maintenance technicians working with hydraulic and pneumatic assemblies that require reliable, leak-free connections.

  • Thread Type: Rp (BSPP) parallel pipe thread for standard BSPP fittings and seals in blind-hole applications.
  • A-Spiral Flute: Optimized spiral flute design for efficient chip evacuation and reduced built-up edge, even in tight blind holes.
  • Material: Powder metal construction delivering enhanced wear resistance and extended tool life under demanding tapping conditions.
  • Coating: TiCN coating lowers friction and increases hardness for higher-speed machining and improved longevity.
  • Handedness: Right-hand threading compatible with common BSPP tooling and assemblies.
  • Size: 1/16 x 28, suitable for small-diameter BSPP threads found in compact components.
  • DIN Standard: Conforms to DIN5156 threading practices for reliable, repeatable results.
  • Application: Specifically designed for blind holes, delivering clean, accurate thread profiles for secure connections.

In practical use, this tap provides consistent, precise Rp BSPP threads in blind holes, enabling reliable seals in hydraulic and pneumatic systems. The combination of powder-metal durability and TiCN coating supports higher cutting speeds, better heat resistance, and longer tool life, making it well-suited for production runs or precision repairs. The A-Spiral flute aids chip removal to minimize snagging and ensure smooth tapping, even in confined workspaces. Ideal for shops that value dependable performance, repeatable results, and efficient workflow when working with small-diameter BSPP threads.
