The Carmex Thread Mills Solid Carbide - Fast Type with Internal Coolant Bore is a high-performance threading tool designed for CNC machinists who demand speed and precision in UN-thread milling. Built for production environments, it combines a large flute count with an integrated coolant bore to deliver fast, clean threads across UNC, UNF, UNEF, and UNS specifications.

• Tool family: Solid carbide thread mill from the FMT/Fast MT line, engineered for high-speed threading and long tool life
• Diameter: 9/16 in
• Shank: MT8 Morse taper shank for secure mounting in standard milling machines
• Flute count: 5–8 flutes to accelerate material removal and improve finish
• Internal coolant bore: Built-in coolant channel for effective cooling, chip evacuation, and reduced built-up edge
• Thread compatibility: Optimized for UN threads, including UNC, UNF, UNEF, UNS
• Material: Solid carbide construction for rigidity and wear resistance

With the FMT/Fast MT design, you can expect shorter cycle times and consistent thread quality even in challenging materials. The high flute count and internal coolant work together to minimize heat, flush chips away, and extend tool life, making it ideal for high-volume production or intricate prototypes that require precise thread engagement. The MT8 shank ensures compatibility with common CNC spindles, enabling reliable performance and quick tool changes.
