The Carmex Long Reach Through-Coolant Thread Mills (Metric, MT7) are precision carbide tools built for threading medium to large metric sizes in deep cavities and at the base of workpieces. Designed for machinists who need reliable, accurate threads in hard-to-reach locations, these mills combine through-coolant efficiency with a rigid, stable design for consistent results.

• Through-Coolant Design: Internal coolant bore enables through-tool cooling, improving chip evacuation and allowing higher cutting speeds and feeds.
• Long Reach Geometry: Optimized for deep pockets and base-side threading, with a rigid tool body that maintains stability even with significant overhangs.
• High Rigidity and Stability: Short cutting length relative to reach minimizes vibrations, enhancing thread accuracy and surface finish.
• Depth Capability: Thread lengths up to 3D are supported, enabling efficient threading in challenging, deep features.
• Metric Thread Milling: Specifically designed for metric thread profiles, delivering reliable, repeatable results across a range of sizes.
• MT7 Shank Compatibility: Precision-ground MT7 shank provides secure seating in standard toolholders for dependable performance.

These tools empower you to thread deep features with confidence, reduce cycle times through higher speeds and feeds, and achieve clean, consistent metric threads even when access is limited. The MT7 long-reach, through-coolant design makes it a versatile choice for precision manufacturing, mold making, and automotive applications where deep, accurate threads are essential.
