The OSG UNC A-Spiral Flute threading tap is built for high-performance tapping of UNC threads in blind holes, delivering clean, precise threads every time. Designed for machinists and manufacturers who demand durability and consistent results, it performs reliably in demanding materials and deep holes.

• Material: Powder metal body delivers exceptional durability, wear resistance, and strength for tough tapping tasks.
• Coating: TiCN coating increases hardness, reduces friction, and extends tool life for high-speed cutting.
• Flute Design: Spiral flute enables efficient chip evacuation in blind holes, reducing friction and chatter.
• Thread Type: UNC A thread form with right-hand operation for standard blind-hole tapping.
• Size & Standard: M6 x 32 with DIN2184-1 compliance ensures compatibility with common blind-hole specifications.

This tap helps you achieve reliable UNC threads in blind holes with fewer reworks and shorter cycle times. The combination of powder-metal construction and TiCN coating means you can push feeds and speeds while maintaining control, accurate thread profiles, and longer tool life. The spiral flute design provides smooth chip removal in recessed holes, making it ideal for automotive, industrial equipment, and precision assembly applications where consistency matters.
