The Carmex MTQ Thread Mills Long Reach Through Coolant (MT7) come in a 12‑pack and are engineered for threading medium to large internal features in deep workpieces. Designed to reach into bases and tight depths with reliable through‑coolant delivery, these tools deliver consistent, accurate threads in demanding setups.

• Long reach with through coolant: Built to access deep internal threads and base features while delivering coolant directly to the cutting edge for better heat management and chip control.
• Internal coolant bore: Integrated coolant channel supports flush cooling and efficient chip evacuation, extending tool life and maintaining accuracy.
• Thread length up to 3D: Capable of threading depths up to three times the nominal diameter, enabling deeper threads without swapping tools.
• MT7 shank: Optimized for solid, rigid engagement in high‑precision machines, promoting stable geometry and concentric threading.
• Rigid tool body: Geometry and build prioritize stiffness to minimize vibration and deflection during heavy cutting.
• High‑speed capability: Designed to support higher cutting speeds and feeds, helping reduce cycle times while preserving thread quality.
• Overhang‑friendly design: Performs reliably with tool overhangs, expanding the range of viable setups and part geometries.
• UN/UNC/UNF/UNEF/UNS compatibility: Ready for common Unified National thread forms, simplifying program creation and workholding decisions.
• Pack size: 12‑piece set ensures you have multiple sizes on hand for quick changeovers and efficient production runs.

Benefits you’ll notice with these MTQ thread mills include faster cycle times without sacrificing precision, improved surface finish from reduced vibration, and dependable threading even in challenging, deep cavities. The through‑coolant design keeps temperatures down at the tool edge and enhances chip removal, which translates to longer tool life and more consistent thread tolerances. Ideal for manufacturing scenarios like engine blocks, hydraulic components, mold bases, and large housings, this MT7 tool family provides the reach and reliability needed to complete complex threads in a single setup.
