Carmex MT line solid carbide internal thread mills deliver precise, cost-efficient threading for UN family threads. Designed for machining professionals, these tools make reliable internal threads in metal parts with consistent results.

• Thread forms supported: Internal threads in UN family formats (UN, UNC, UNF, UNEF, UNS)
• Size: 1/4"-20 thread size for common UN threading applications
• Shank: MT7 Morse Taper shank for secure toolholding and broad machine compatibility
• Material: Solid carbide construction for rigidity, wear resistance, and long tool life
• Flute count: 3–5 flutes to optimize cutting action, chip evacuation, and finish
• Cutting geometry: Geometry optimized for clean, accurate internal thread generation with minimal chatter

Use cases span precision assemblies in automotive, aerospace, and general mechanical components where reliable UN-threaded connections are essential. The 3–5 flute design supports higher feed rates and efficient material removal, helping reduce cycle times without sacrificing thread accuracy. Ideal for both prototyping and production environments where consistency and durability matter most.
