The Carmex MTD Thread Mill is a precision carbide tool engineered to drill, chamfer, and thread mill internal holes in a single pass. Designed for high-volume production and UN/UNC/UNF/UNEF/UNS thread forms, it delivers consistent, ready-to-use threads with fewer tool changes.

• Two-fluted drill/thread milling cutter: Performs drilling, chamfering, and thread milling in one operation to shorten cycle times and simplify setups.
• 45° chamfer: Creates a reliable lead-in for clean, accurate thread starts in mass-production environments.
• Internal coolant bore: Directs coolant to the cutting edges and the interior of the hole for effective cooling and chip control.
• MT7 Sub-Micron carbide grade: Balances high hardness with toughness to withstand demanding materials and long production runs.
• PVD triple coating: Enhances wear resistance and provides smooth cutting performance for extended tool life.
• Right- and left-hand internal threads: Flexible threading capability without the need to change tools.
• Suitable for blind and through holes: Versatile for a range of hole depths and workpiece geometries.

By consolidating drilling, chamfering, and thread milling into a single toolpath, the Carmex MTD Thread Mill reduces cycle times and minimizes tool changes without compromising thread quality. The combination of a precisely engineered 45° lead, advanced carbide grade, and protective coatings delivers consistent, high-quality internal threads across UN/UNC/UNF/UNEF/UNS specifications. Ideal for high-volume manufacturing, mold making, and precision assemblies, this tool helps shops improve throughput while maintaining dependable thread integrity.
