The OSG UNC Spiral Flute Threading Tap No. 8 x 32 is a precision internal threading tool designed for blind-hole work, built for machinists and shops that demand reliable, accurate threads.

• Tool Type: UNC spiral flute threading tap for internal threads in blind holes
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
• Coating: Steam oxide coating to improve durability and heat tolerance
• Flute Design: Spiral flute geometry promotes efficient chip evacuation in confined blind-hole environments
• Size: No. 8 diameter with 32 threads per inch (No. 8 x 32 UNC)
• Application: Ideal for precision threading in steel and alloy workpieces where access is limited to blind holes
• Brand Advantage: Leverages OSG’s advanced threading technology for consistent, high-quality threads
• Durability & Life: Cobalt-enhanced substrate and steam-oxide coating extend tool life under demanding cutting conditions

Use this tap to create clean, accurate internal threads with reliable alignment and minimal walk-off. The combination of cobalt-enhanced HSS and steam-oxide coating delivers better heat resistance and longer tool life, helping you reduce downtime and maintain tight tolerances on critical components. Whether assembling machinery, repairing housings, or manufacturing high-precision parts, this No. 8 x 32 UNC spiral flute tap supports repeatable results and efficient machining workflows.
