Carmex Thread Mills Carbide Drill Mill - UN (UNC UNF UNEF UNS) - x 28 - MT7

The Carmex MTD Thread Mill is a carbide drill-mill that combines drilling, chamfering, and internal thread milling into a single, efficient operation. Designed for high‑volume production, it delivers consistent thread quality with fewer tool changes.

• Two-fluted design: Optimizes cutting stability for drilling and thread milling in one pass, with reliable chip control.
• 45° chamfer: Creates a precise starting chamfer for threads, reducing finishing steps and ensuring clean engagement.
• Internal coolant bore: Delivers coolant through the tool to cool the cut and evacuate chips for extended tool life.
• MT7 shank: Rigidity and compatibility with standard MT7 holders for dependable performance in demanding setups.
• Thread compatibility: Supports internal threads in UNC, UNF, UNEF, and UNS series, accommodating a wide range of applications.
• Left and right-hand capability: Accepts both directions for internal threading without the need for multiple tools.
• Coating and substrate: Optimised MT7 Sub-Micron carbide grade with a PVD triple coating for high hardness, toughness, and smooth cutting.
• Versatile hole applications: Suitable for both blind and through holes, enabling a single tool to handle diverse manufacturing needs.

This thread mill delivers tangible production benefits: shorter cycle times from combining drilling, chamfering, and threading; fewer tool changes; and consistently high-quality internal threads with improved surface finish. The combination of a robust two-fluted geometry, internal coolant, and advanced carbide coating helps maintain edge life and accuracy across demanding production runs. Ideal for shops focused on efficiency, repeatability, and fast setup in precision threading tasks.
