Description

The Carmex MTQ Thread Mills Long Reach Through Coolant are precision threading tools designed for medium to large threads in deep cavities and base-side features. Engineered for stability and high-speed performance, they deliver reliable thread formation where conventional tools struggle.

  • Package quantity: 4-piece set of long-reach, through-coolant thread mills designed for metric threads.
  • Through coolant design: Coolant is delivered through the tool to the cutting zone, improving chip evacuation and extending tool life in challenging deep pockets.
  • Long reach with MT7 shank: Optimized geometry paired with an MT7 interface provides high rigidity and secure engagement in overhang applications.
  • Internal coolant bore: Built-in coolant channel ensures effective lubrication directly at the flute/root, reducing heat and wear during threading.
  • Thread length capability up to 3D: Capable of threading lengths up to 3 times the thread diameter, enabling deeper threading in a single operation.
  • Overhang-friendly design: Short cutting length combined with a long reach supports aggressive setups without sacrificing stability.
  • Metric threading: Specifically optimized for metric thread profiles, delivering consistent pitch accuracy and clean thread forms.

These features translate into real-world benefits: you can thread deeply into workpieces without repositioning, leverage higher cutting speeds and feeds thanks to the tool’s rigidity, and achieve precise, repeatable thread quality even in base-side locations. The MTQ line minimizes vibrations and can shorten cycle times, helping you meet tight tolerances and finish projects faster with less post-processing. Ideal for manufacturing fasteners, hydraulic components, and precision assemblies, this long-reach thread mill is built to reach what others can’t.
