The Carmex MT line Internal Thread Mill is a solid carbide solution built for precise, efficient internal threading on CNC machines. Designed for shops that need reliable UN-family threads (UNC, UNF, UNEF, UNS) in a cost-conscious package, this 3/4" diameter tool with a 10 TPI thread form delivers consistent results across production runs.

• Diameter & Thread Size: 3/4" diameter with a 3/4-10 UNC internal thread form, compatible with UNC, UNF, UNEF, and UNS standards.
• Flute Count: 3–5 flutes to optimize cutting action, finish quality, and chip evacuation during threading.
• Material: Solid carbide construction for rigidity, wear resistance, and long tool life in demanding threading applications.
• Shank Type: MT7 Morse taper shank for secure, repeatable seating in standard toolholders.
• Design & Efficiency: Geometry engineered to streamline the threading process, enabling smooth cutting and reliable thread formation with fewer passes.
• Applications: Ideal for internal threading in holes of various depths on a range of materials, supporting both prototypes and high-volume production needs.

The MT thread mills are a practical, cost-effective choice for shops aiming to simplify threading workflows without sacrificing thread integrity. The multi-flute design and carbide hardness translate to precise thread profiles, reduced cycle times, and longer tool life, helping you achieve repeatable results in standard UN-thread sizes every run.
