The OSG RC BSPT A-Straight Flute Tap is a precision threading tool built for cutting British Standard Pipe Taper (BSPT) threads. Designed for both through-hole and blind-hole applications, it delivers reliable, consistent BSPT threads in demanding metalworking environments.

• Thread Type: BSPT (British Standard Pipe Taper) threading for standard pipe fittings.
• Flute Design: A-Straight Flute promotes straight chip flow, ideal for long-chip materials.
• Material: Powder Metal substrate for enhanced wear resistance and durability.
• Coating: TiCN-coated surface reduces friction and improves heat resistance, extending tool life.
• Applications: Suitable for both through-hole and blind-hole BSPT tapping (DIN5156).
• Size / Pitch: 3/8 in nominal diameter x 19 BSPT thread profile.
• Direction: Right-hand threading for standard tapping operations.
• Standards: DIN5156 compliance ensures compatibility with widely used BSPT fittings.

With its powder-metal base and TiCN coating, this tap is built to withstand the heat and wear of repeated BSPT tapping, delivering longer tool life and more consistent thread quality. The straight flute design ensures efficient chip evacuation from deep or through-holes, reducing the risk of clogging and imperfect threads. The right-hand orientation aligns with common machining setups, making it a reliable choice for pipe fittings, hydraulic components, and other BSPT-driven projects. DIN5156 support adds confidence that your BSPT threads will mate smoothly with standard fittings, helping you achieve precise, repeatable results with every tap.
