The OSG Threading Tap Rp (BSPP) A-Spiral Flute is a precision cutting tool engineered to create British Standard Pipe Parallel (BSPP) threads in blind holes. Designed for machinists and shops that demand clean, dependable BSPP threads, this tap delivers consistent results and long tool life.

• Thread type: Rp (BSPP) with right-hand rotation, sized 3/8 x 19 for standard BSPP applications
• A-Spiral flute design: Optimized for efficient chip evacuation in confined blind holes, reducing snagging and stalling
• Material: Powder metal construction for enhanced durability and wear resistance
• Coating: TiCN coating lowers friction and increases hardness, enabling higher speeds and improved wear performance
• DIN standard: DIN5156 compliance ensures precise BSPP thread geometry compatible with standard fittings

This tap is ideal for machining BSPP threads in tight or restricted cavities, where reliable chip control and durable performance matter most. The combination of powder-metal robustness, TiCN hardness, and an A-Spiral flute delivers clean, accurate threads with fewer inserts or reworks, making it well-suited for hydraulic, pneumatic, and piping assemblies that rely on dependable BSPP connections.
