Description
The OSG Rp BSPP A-Spiral Flute Tap is a high-performance threading tool designed to create precise BSPP (British Standard Pipe Parallel) threads in blind holes. Built for professional machinists and production environments, it delivers clean, repeatable threads for BSPP fittings and hydraulic components.
- Thread type: Rp (BSPP) right-hand thread for standard BSPP fittings.
- Flute design: A-Spiral flute provides efficient chip evacuation in blind holes, reducing clogging and rework.
- Material: Powder metal construction delivers excellent durability and wear resistance for demanding machining.
- Coating: TiCN coating lowers friction, increases hardness, and extends tool life at higher speeds and temperatures.
- Size and standard: 1/2 in. diameter with 14 TPI; DIN 5156 compatibility ensures consistent, accurate threads.
- Applications: Suitable for both blind holes and through-hole tapping, ideal for BSPP fittings in hydraulic and pneumatic systems.
This tap helps you achieve accurate BSPP threads quickly, with reduced tool wear and fewer reworks. The TiCN coating and powder-metal core support higher-speed tapping in tougher materials, while the spiral flute design ensures reliable chip clearance in tight blind holes. Rely on its proven geometry and construction for dependable performance in everyday machining of BSPP components.
