The OSG UNC Spiral Flute Threading Tap No. 8 x 32 is a precision internal-threading tool designed for metalworking professionals who need clean, accurate threads in blind-hole applications.

• Thread size: No. 8 x 32 UNC
• Flute design: Spiral flute for efficient chip evacuation in blind-hole tapping
• Material: HSS-E (high-speed steel with cobalt) for durability and heat resistance
• Coating: Steam oxide finish to boost wear resistance and lubricity
• Application: Intended for tapping internal threads in blind holes
• Compatibility: UNC threading standard (No. 8-32)

This tap is built to deliver consistent thread quality under demanding conditions. The spiral flute design minimizes chip buildup, reducing heat and binding during deep or narrow-hole tapping. The HSS-E cobalt composition provides strength and heat tolerance, while the steam oxide coating extends tool life by reducing wear and galling. Rely on this tool for precise, repeatable threads that meet the needs of critical assemblies and repeatable machining tasks.
