Carmex MTQ Long Reach Through-Coolant Thread Mills are the threading solution designed for machinists tackling medium to large threads in deep pockets and base-level features. This 20‑piece MT7 set provides reliable, precise threading with through‑coolant delivery across UN, UNC, UNF, UNEF, and UNS standards.

• Thread compatibility: Covers UN, UNC, UNF, UNEF, and UNS threads for versatile use in a single set.
• Long reach design: Optimized for deep holes, pockets, and base-side threading without repositioning the workpiece.
• Through‑coolant bore: Internal coolant channel delivers coolant directly to the cutting edge for improved chip evacuation and tool life.
• MT7 shank: Strong, rigid interface compatible with standard MT7 milling spindles for steady performance.
• Thread length capability: Thread lengths up to 3D to handle longer engagement in challenging geometries.
• High rigidity and stability: Engineered to minimize vibrations, enabling higher cutting speeds and feeds and shorter cycle times.
• Overhang support: Designed to maintain performance when used with extended reach in complex setups.
• Low cutting forces: Short cutting length helps keep cutting forces manageable, improving finish and tool life.
• Included quantity: 20 tools in the set, ready for a range of threading tasks.

By combining a long-reach profile with through-coolant delivery, these threads mills deliver precise, repeatable results even in deep cavities and base features. The MTQ design emphasizes rigidity to reduce chatter, enabling faster speeds and feeds to shorten cycle times. An internal coolant bore keeps chips moving away from the cutting edge, enhancing surface finish and extending tool life. With overhang capability and a compact cutting length, you can tackle base threading and deep-pocket work in a single setup, boosting productivity and consistency across jobs.
