Carmex Solid Carbide External UNJ Thread Mill is a precision tool designed for engineers and machinists who need accurate external threads on UNJ forms. Sized for 6 mm diameter with a 32 mm reach and MT7 shank, it delivers dependable performance in tight tolerance applications.

• Diameter and length: 6 mm diameter with 32 mm length of cut for controlled, consistent threading.
• Shank: MT7 Morse taper shank for secure, rigid mounting on compatible CNC machines.
• Material: Solid carbide construction provides wear resistance and durable cutting stability for repetitive threading.
• Thread form compatibility: External UNJ threading capability supporting UNJ, UNJC, UNJF, UNJEF, and UNJS forms.
• Flute geometry: Spiral flutes engineered to enhance surface finish on threaded features and reduce chatter.
• Flute count: Multi-flute design with 3–5 flutes to maximize material removal and shorten cycle times.

This external UNJ thread mill is built to improve productivity without sacrificing precision. The combination of spiral flute geometry and a 3–5 flute configuration minimizes finishing passes while delivering cleaner thread starts and smoother engagement. The MT7 shank ensures solid seating and repeatable performance across production runs, making it well suited for aerospace fasteners, precision hydraulic components, and other high-accuracy threaded parts. Whether upgrading a milling cell or optimizing a dedicated thread-cutting operation, this Carmex tool helps you achieve tight tolerances, excellent surface quality, and faster overall throughput.
