The OSG Rp (BSPP) A-Spiral Flute Threading Tap is a precision tool designed for machinists who need British Standard Pipe Parallel threads in blind holes. Built for reliability in plumbing, hydraulic, and pneumatic assemblies, it delivers clean, accurate BSPP threads with long tool life.

• Thread Type: Rp (BSPP) parallel thread, DIN5156 compliant for BSPP fittings.
• A-Spiral Flute Design: Optimized for chip evacuation, reducing clogging and improving performance in blind-hole tapping.
• Material: Powder metal body offering enhanced wear resistance and extended tool life in demanding materials.
• Coating: TiCN coating lowers friction, increases hardness, and supports higher-speed machining with better heat resistance.
• Size & Orientation: Right-hand thread, 3/4" diameter with 14 threads per inch (3/4 x 14).
• Hole Type: Specifically suited for blind holes, delivering consistent, clean BSPP threads for reliable fittings.

With the TiCN-coated powder metal construction and the A-Spiral flute geometry, this tap provides smooth cutting action, steady chip control, and long-lasting performance. The precise DIN5156 threading profile ensures compatibility with standard BSPP fittings, helping you achieve leak-tight, dependable connections in hydraulic and pneumatic systems. Ideal for production runs or repair work, this tap supports repeatable results, reduced downtime, and accurate threading across materials commonly encountered in pipe fittings and mechanical assemblies.
