The OSG Rp (BSPP) A-Spiral Flute threading tap is a precision tool for creating British Standard Pipe Parallel threads in blind holes. Designed for machinists and production environments, it delivers clean, reliable BSPP threads with consistent performance.

• Thread type: Rp (BSPP) threads per DIN5156 for blind-hole applications, ensuring standard compatibility with BSPP fittings.
• Flute design: A-Spiral flute promotes efficient chip evacuation and reduces clogging in tight blind holes.
• Material: Powder metal construction delivers excellent wear resistance and longer tool life under demanding cutting conditions.
• Coating: TiCN coating lowers friction, increases surface hardness, and supports higher-speed machining and temperature tolerance.
• Cut direction: Right-hand operation, suitable for clockwise rotation in typical milling and drilling setups.
• Size: 1/4 x 19 BSPP threading, providing a precise fit for common BSPP components.
• Applications: Optimized for creating BSPP threads in blind holes and for through-hole projects that require reliable sealing interfaces.

These features translate into real-world benefits: precise, clean threads that resist seizing and galling, improved chip control to minimize rework, and extended tool life in high-speed or high-temperature environments. The TiCN coating enhances performance during repeated threading cycles, while the powder-metal body offers durability without adding excessive weight. Ideal for hydraulic, pneumatic, and fluid-handling assemblies that rely on robust BSPP connections.
