The Carmex Thread Mills Carbide Drill Mill is a precision multitool engineered for high‑volume internal thread production. It combines drilling, chamfering, and thread milling in a single pass, making it ideal for shops that require fast, repeatable internal threads in UNC, UNF, UNEF, and UNS forms.

• Two-fluted drill/thread milling cutter: Performs drilling and thread milling in one operation for streamlined workflows and reduced tool changes.
• 45° chamfer: Provides an accurate thread start, improving cycle reliability in mass production environments.
• Internal coolant bore: Delivers coolant directly to the cutting edge to improve chip control and extend tool life.
• MT7 Sub-Micron carbide grade: Combines exceptional hardness and toughness with a tight, precise microstructure for consistent performance.
• PVD triple coating: Low-friction, high-performance coating for smooth cutting and longer tool life in demanding materials.
• Internal threading versatility: Fits both right- and left-hand internal threads, usable for blind and through holes with the same tool.
• Thread forms supported: Designed to accommodate UNC, UNF, UNEF, and UNS internal threads for flexible applications.
• High thread surface quality: Delivers reproducible, smooth threads suitable for precision assemblies and functional fits.

Designed for mass production, this tool minimizes cycle times by eliminating tool changes and consolidating multiple operations into one efficient cut. The combination of a robust carbide core, advanced coating, and integrated coolant makes it a reliable choice for challenging materials and high-output environments. Whether you’re equipment‑gating for automotive, aerospace, or general engineering applications, this Carmex thread mill helps you achieve consistent thread integrity with fewer passes and tighter tolerances.
