Carmex Thread Mills Solid Carbide - Fast Type - With Internal Coolant Bore - Metric - M4 x 0.7 - MT8

Carmex FMT/Fast MT solid carbide thread mills are built for speed and precision, tailored for metric M4 x 0.7 threading on CNC machines. Designed for production environments, they help you complete threads faster without compromising accuracy.

• Tool family: FMT/Fast MT line of solid carbide thread milling tools for high-efficiency threading.
• Shank & size: MT8 shank compatible with standard MT tool holders; designed for M4 x 0.7 metric threads.
• Flute count: High flute count (5–8) to increase material removal rates and shorten cycle times.
• Internal coolant bore: Built-in coolant channel delivers coolant directly to the cutting edges for better cooling and chip evacuation.
• Material quality: Solid carbide construction delivers hardness, wear resistance, and reliable performance in demanding materials.
• Geometry & precision: Optimized thread-form geometry provides clean, accurate threads with consistent finish.

This tool is ideal for machinists who need fast, repeatable metric threading in production runs, prototypes, or repair work. The combination of a high flute count and an internal coolant bore enables higher feed rates, improved heat management, and longer tool life, translating to lower overall manufacturing costs and steadier throughput. Use it for through-hole and blind-hole applications where M4 x 0.7 threads must meet tight tolerances and smooth surface finish, across a range of metallic materials. The MT8 interface ensures secure, quick tool changes on compatible CNC machines, making it a dependable choice for high-demand threading tasks.
