Carmex MT Line Thread Mills in solid carbide deliver precise internal and external NPT threading in a compact, cost-efficient package. Designed for machinists and job shops, these MT7-thread milling tools streamline production by handling both sides of the thread in a single tool.

• Tool Type: Thread mill capable of creating both internal and external NPT threads with a single tool, reducing setup and tool changes.
• Material: Solid carbide for high rigidity, wear resistance, and consistent thread profiles over many cycles.
• Threading Capability: Internal and external thread milling (NPT) to produce accurate pipe-thread features directly on the mill.
• Thread Sizes: Compatible with 1/16" and 1/8"-27 NPT thread forms for common small-diameter applications.
• Shank Type: MT7 Morse taper shank for secure, rigid mounting in compatible milling machines.
• Flute Count: 3–5 flutes designed to optimize cutting action, chip evacuation, and surface finish during threading.
• Design Focus: Optimized for efficient threading workflows, delivering reliable performance at a lower tooling cost per thread.

By pairing internal and external NPT thread milling in one carbide tool, you reduce inventory, simplify tooling strategies, and achieve repeatable thread quality. The multi-flute geometry supports steady chip control and smooth cutting, helping you maintain tight tolerances on small-diameter threads. Ideal for production runs and development work alike, this tool helps you move from prototype to production faster without compromising thread accuracy.
