The Carmex Spiral Flute UNC Supercut Tap is engineered for machinists who demand precise Unified National Coarse threading in demanding materials. Crafted with powder metal construction, it delivers reliable performance in high-speed tapping tasks.

• Thread type: Unified National Coarse (UNC) threading for standard coarse threads
• Size: 3/8 in diameter, 16 TPI (3/8-16 UNC)
• Flute design: Spiral flute for efficient chip evacuation, reducing clogging and binding during tapping
• Material: Powder metal construction offers durability and wear resistance under high-speed use
• Geometry: Supercut design provides optimized cutting action and smoother entry for longer tool life
• Applications: Ideal for high-speed threading operations and challenging materials where clean, consistent threads are essential

This tap helps you achieve consistent thread engagement with fewer reworks, thanks to improved chip clearance and a robust build. The combination of spiral flute geometry and powder metal construction supports longer tool life in production runs, while the 3/8-16 UNC size covers a wide range of common fastening and assembly needs. Perfect for machine shops, fabrication environments, and DIY enthusiasts tackling durable metal projects.
