The Carmex MTQ Thread Mills Long Reach Through Coolant are precision threading tools designed for metric threads with a 1.5 mm pitch, optimized for deep and hard-to-reach features. Built for machinists who need reliable, accurate threads in medium to large sizes, including threads at the base of the workpiece, these tools deliver steady performance with through-coolant efficiency.

• Long reach with through coolant: designed to reach deep into pockets and bases while delivering coolant through the tool for effective cooling and chip removal.
• Internal coolant bore: direct coolant to the cutting edge to maintain temperature control, improve tool life, and promote consistent thread quality.
• MT7 shank compatibility: engineered for precise fit in MT7 toolholders, ensuring reliable alignment and rigidity during demanding threads.
• High rigidity and stability: minimizes vibrations and deflection, enabling higher cutting speeds and feeds for faster cycle times without sacrificing accuracy.
• Overhang-capable design: supports extended reach setups without compromising precision, expanding the range of workholding and fixturing options.
• Thread length up to 3D: accommodates long-thread applications within a single pass, reducing rework and setup changes.
• Metric M x 1.5 threading: specifically optimized for metric threads with a 1.5 mm pitch, delivering consistent thread form across varied materials.

With the MTQ Long Reach Through Coolant thread mills, you gain precise, efficient threading where space is limited and access is challenging. The combination of short cutting length and high rigidity reduces cutting forces, supporting clean thread profiles and improved surface finish. The internal coolant and through-coolant design improve heat management and chip evacuation, enabling higher speeds and feeds and shorter cycle times. This makes the tool well-suited for mold and die work, aerospace components, and automotive assemblies where deep, accurate threads are critical. The MT7 shank and overhang-capable design provide versatile, stable performance across a range of materials and thread sizes, making this tool a dependable choice for demanding internal threading tasks.
