The OSG Rp (BSPP) A-Spiral Flute threading tap is a precision tapping solution designed for creating British Standard Pipe Parallel threads in blind holes. Built for machinists who demand reliable, repeatable BSPP threading in compact components, this tap delivers clean, accurate results with every use.
- Thread type: Rp (BSPP)—British Standard Pipe Parallel threads for blind-hole applications
- Flute design: A-Spiral flute for efficient chip evacuation and smoother cutting
- Material: Powder metal body for enhanced durability and wear resistance
- Coating: TiCN coating reduces friction and increases hardness for longer tool life and higher cutting speeds
- Drive/hand: Right-hand threading for standard tapping operations
- Hole compatibility: Ideal for blind holes (DIN5156) while also performing well in through-hole scenarios
- Size / pitch: 1/8 x 28 for precise BSPP threading in small components
- DIN standard: DIN5156 specification support for BSPP tapping
This tap is engineered to deliver dependable performance in tight spaces, with a focus on clean thread formation and extended tool life. The TiCN coating and powder-metal construction work together to minimize wear in demanding environments, enabling higher cutting speeds and better heat resistance. The spiral flute aids chip management, reducing the risk of binding and broken taps in both blind-hole and slim-profile applications. Whether you’re fabricating hydraulic fittings, pneumatic lines, or compact plumbing components, this tap helps you achieve precise BSPP threads that seal reliably and perform consistently over time.
