Carmex Thread Mills Solid Carbide - Internal & External Thread - NPT - 1/2, 3/4 x 14 - MT7

Carmex MT Thread Mills deliver precise, cost‑effective threading for both internal and external NPT features, built around a solid carbide core and a reliable MT7 shank. Designed for machinists who value consistency and efficiency, these tools help you produce clean, accurate threads in fewer passes.

• Solid carbide construction: High rigidity and wear resistance for stable, repeatable thread profiles across multiple machines and materials.
• MT7 shank: Standard milling interface for broad compatibility with common tool holders and CNC setups.
• Internal & external threading (NPT): Flexible capability to cut both bore threads and external pipe threads in a single operation.
• 3–5 flute design: Optimized geometry for efficient material removal, improved chip evacuation, and better surface finish.
• Sizes supported: Suitable for 1/2" and 3/4" nominal NPT threads with 14 TPI, enabling common pipe-thread applications.
• Cost‑effective threading solution: Multi-flute efficiency and carbide durability reduce cycle times and tooling costs in production environments.

These MT thread mills are well suited for workshops and production floors that need reliable threading without the complexity of changing tools frequently. Use them for threaded bores on housings, fittings, hydraulic components, and other assemblies requiring precise NPT threads. Pair with appropriate feeds and speeds to maximize tool life and finish, and you’ll enjoy consistent results across repeated runs and different materials.
