The Carmex carbide thread mill is a precision internal-threading tool designed for machinists who demand clean, reliable threads in metal parts. Built for versatility and longevity, it’s ideal for assemblies, fixtures, and projects where accurate internal threads matter.

• Thread Mill Type: Single-point carbide thread mill with a full-profile geometry for cutting internal threads.
• Size & Shank: 5/16" diameter, 14 x 14 size with MT11 Morse-taper shank for compatible toolholding.
• Internal Threading Capabilities: Supports internal threads including ISO M1 x 0.25 and 0-80 UNF; capable of ACME thread profiles as part of the line.
• Depth Capability: Thread depth up to 3.5 × the thread diameter, depending on profile, enabling deep, accurate threads in a single setup.
• Flutes: Multi-flute design (3–4 flutes) for efficient chip evacuation and stable cutting in a range of materials.
• Material & Coating: MT11 ultra-fine sub-micron carbide grade with triple blue PVD coating for reduced wear and longer tool life.

This tool delivers precise thread forms with tight tolerances, minimizing rework and enhancing hole quality. The combination of carbide hardness, advanced MT11 grade, and specialized coating translates to longer tool life, better surface finish, and reliable performance in challenging materials. Whether you're fabricating aerospace components, automotive fixtures, or precision molds, this internal-thread mill provides a robust, repeatable solution for high-quality threads in blind or through holes.
