The Carmex Thread Mills Solid Carbide external tool is engineered for precise UNJ thread milling, delivering reliable, high-quality external threads in demanding materials. Designed for professional workshop environments, it combines robust carbide construction with a geometry aimed at top-tier surface finish and efficiency.

• Material: Solid carbide construction for outstanding rigidity, wear resistance, and long tool life in tough metals.
• Threading compatibility: External thread mill compatible with UNJ thread forms (UNJC, UNJF, UNJEF, UNJS) for versatile applications.
• Size and geometry: 12 mm diameter with 18 mm length of cut, optimized for consistent thread pitch and accuracy.
• Shank type: MT7 taper shank for secure, high-torque engagement on compatible CNC machines.
• Flute design: Spiral flutes that enhance surface finish on threaded features and improve chip evacuation during cuttings.
• Flute count: Multi-flute configuration (3–5 flutes) to balance fast material removal with precise thread quality.

This tool is ideal for manufacturing teams focused on repeatable UNJ threads in automotive, aerospace, and industrial components. The combination of spiral flute geometry and a multi-flute count translates to smoother threading operations, fewer passes, and cleaner, more consistent thread profiles—helping parts assemble with reliable torque and engagement. The MT7 shank provides stable drive in rigid setups, enabling high-performance milling without sacrificing precision.
