Designed for threading medium to large UN-thread profiles in deep workpieces, including base-area applications, Carmex MTQ Long Reach Through Coolant thread mills deliver precision and versatility. This pack of 20 tools (MT7 shank) combines rigidity, efficiency, and deep-pocket capability to streamline complex threading tasks.

  • UN thread compatibility: Precisely machine UNC, UNF, UNEF, and UNS thread profiles with a dedicated through-coolant design.
  • Long reach with through coolant: Extended reach enables threading in deep cavities and hard-to-access areas while delivering flood cooling directly through the tool.
  • High rigidity and stability: Built to minimize vibrations, supporting smoother cuts and tighter tolerances in challenging workpieces.
  • Thread length up to 3D: Flexible accommodation for longer thread geometries without repositioning or secondary operations.
  • Overhang-capable design: Supports machining setups that require overhanging reach for base-level or recessed threads.
  • Short cutting length for lower cutting forces: Reduced cutting length translates to more stable cuts and longer tool life in demanding applications.
  • MT7 shank: Compatible with standard MT7 toolholding systems for reliable seating and precision
  • Pack size: 20 pieces per order, providing a ready supply for multiple thread sizes and jobs without frequent reordering.

These MTQ thread mills are ideal for production environments where deep-threading in large or medium-size UN threads is routine. Expect consistent thread quality, reduced cycle times thanks to higher speeds and feeds, and dependable performance when threading in base- or recess-area features. The combination of long reach, through-coolant cooling, and robust rigidity helps you tackle challenging geometries with confidence, while the included pack of 20 ensures you have the right tool on hand for diverse projects.
