The Carmex Fast Type solid carbide thread mill is a high-performance tool built for fast, precise thread milling on CNC machines. Designed for production environments that require UNC/UNF/UNE.../UNS threads, it delivers rapid cycle times without sacrificing accuracy.

• Diameter x pitch: 5/16" diameter with 18 threads per inch (5/16-18)
• Thread standards: Supports UN, UNC, UNF, UNEF, UNS threading
• Shank: MT8 Morse taper shank for secure toolholding
• Material: Solid carbide for exceptional rigidity and wear resistance
• Flute count: 5–8 flutes to reduce machining time while maintaining finish quality
• Internal coolant bore: Built-in coolant channel ensures efficient cooling and chip evacuation
• Fast Type geometry: Optimized for high-speed threading with consistent chip control
• Applications: Ideal for threading through-holes and through- or blind-hole work on metal components

The combination of a high-flute design and an internal coolant bore translates to faster cycle times, better temperature management, and cleaner thread profiles. The solid carbide construction provides the rigidity needed to maintain precise tolerances across challenging materials, while the MT8 shank ensures broad compatibility with common CNC spindles. This tool is well-suited for automotive, aerospace, and general manufacturing tasks where reliable UNC/UNF/UNE... thread milling is essential for production throughput and repeatable results.
