The Carmex Thread Mills Long Reach Through Coolant MT7 is a precision threading solution designed for UN threads, engineered to tackle medium to large sizes in deep workpieces and base features with consistent accuracy.

• Thread forms supported: Universal UN family compatibility (UNC, UNF, UNEF, UNS) for versatile applications.
• Long reach / deep threading: Optimized geometry enables reliable threading in deep pockets and challenging base locations.
• Through coolant: Internal coolant bore delivers coolant directly to the cutting edge for efficient cooling and chip evacuation.
• Thread lengths up to 3D: Capable of threading lengths up to three times the thread diameter in a single setup.
• MT7 shank: Robust MT7 interface ensures secure tool retention in standard milling machines.
• High rigidity and stability: Designed to minimize vibrations, supporting higher cutting speeds and feeds for faster cycle times.
• Overhang capability: Suitable for setups that require tool overhang without sacrificing performance.
• Low cutting forces: Short cutting length reduces load on the tool and machine, promoting stable, precise threads.

In practice, this thread mill delivers clean, consistent UN threads even in recessed or base-level features. The through-coolant design helps maintain tool life and finish quality by managing heat and swarf in demanding deep-threading tasks. With its rigid construction and ability to handle overhangs, the MT7 version supports efficient multipass or single-pass threading workflows, reducing cycle times while maintaining tight tolerances. Ideal for aerospace, automotive, and general engineering applications where reliable UN threading in hard-to-reach areas is essential.
