The OSG RC BSPT A-Spiral Flute threading tap is a precision tool designed for professionals who need reliable BSPT threads in blind-hole applications. Built from powder-metal and TiCN-coated, it delivers durable performance for demanding materials and tight tolerances.

• Thread type: BSPT (British Standard Pipe Taper), right-hand thread, 1/4" diameter with 19 threads per inch (1/4 x 19)
• Flute geometry: A-Spiral flute design that facilitates chip evacuation, ideal for blind-hole tapping and tight starts
• Material: Powder-metal body offering enhanced wear resistance and toughness for long tool life
• Coating: TiCN coating reduces friction and improves heat resistance for faster cutting and extended tool life
• Standards: DIN5156-compliant designation for BSPT thread accuracy and compatibility
• Applications: Optimized for blind-hole BSPT threading and through-hole work where reliable chip evacuation matters

The powder-metal construction delivers wear resistance and toughness that stand up to demanding materials and high-production environments. The TiCN coating lowers friction and improves heat resistance, enabling faster speeds and longer tool life. The A-Spiral flute actively pulls chips out of the hole, reducing binding and enhancing start-up performance in blind-hole scenarios. Together, these features support consistent BSPT thread quality and minimal downtime for hydraulic, pneumatic, and fluid-handling assemblies that require DIN5156 tolerances.
