The Carmex MTQ Long Reach Through Coolant Thread Mills are engineered to thread medium to large UN-series threads in deep pockets and at the base of workpieces. Designed for MT7 tooling, they deliver robust rigidity and efficient coolant delivery to tackle demanding deep-threading tasks with confidence.

• Thread compatibility: supports UN, UNC, UNF, UNEF and UNS thread types for versatile threading in a single tool family
• Through-coolant design: integrated coolant bore enables effective cooling and chip evacuation directly at the cutting edge
• Long reach with overhang capability: optimized geometry allows threading deep features and base regions without compromising stability
• Rigidity and stability: high‑stiffness construction minimizes vibrations for clean thread profiles and consistent results
• Short cutting length: shorter engagement reduces cutting forces while maintaining productive chip loads
• Thread length capacity: accommodates thread lengths up to 3D for versatile deep-threading applications
• Shank compatibility: MT7 Morse taper shank for reliable toolholding and balanced rigidity in standard CNC executions

In practice, this tool delivers precise, repeatable threads in challenging deeper geometries, helping you reduce cycle times through higher cutting speeds and feeds. The through-coolant bore supports better temperature control and chip management, preserving surface finish and extending tool life even in arduous deep-threading scenarios. Ideal for production environments that require robust performance on medium to large UN-threaded features, the MTQ long-reach thread mill combines depth capability, coolant efficiency, and dependable stability in a single, easy-to-integrate solution.
