The Carmex MT7 Solid Carbide Internal Thread Mill is a precision threading solution built for metalwork where accurate internal threads are required. Designed for machinists who value reliability and cost-efficiency, it delivers consistent results in a compact MT7 shank.

• Internal threading capability: Specifically engineered to cut internal threads to UNC/UNF/UNEF/UNS standards in a single operation.
• Thread size: 7/16 x 14 (major diameter 7/16", 14 TPI) for common fastener compatibility and versatile use.
• Flute count: 3–5 flutes for stable cutting, improved chip evacuation, and precise thread formation.
• Material: Solid carbide construction for exceptional wear resistance, rigidity, and long tool life in demanding applications.
• Shank: Morse Taper 7 (MT7) shank for secure, versatile toolholding in compatible milling spindles.
• Applications: Ideal for internal threading in through-holes and blind-holes across a range of metal workpieces.

This thread mill replaces traditional tapping in many workflows, offering consistent thread quality, reduced cycle times, and the ability to machine complex hole geometries with a single tool. The multi-flute design enhances cutting efficiency and surface finish, making it a reliable choice for production runs, maintenance, and prototype development where precise internal threads are essential.
