Meet Carmex MTQ Long Reach Through-Coolant thread mills — a precision threading tool designed for medium to large threads in deep workpieces, including base-area features. Built for rigidity and reliability, it supports through-coolant operation to keep cutting zones cool and clear.

• Through-Coolant bore: Internal coolant delivers coolant directly through the tool to the cutting edge, improving cooling and chip evacuation in deep pockets.
• Long-reach geometry: Extended cutting length enables threading in tall workpieces and from underside surfaces without repositioning.
• High rigidity and stability: Robust tool body minimizes chatter for clean, accurate thread profiles even at higher feeds.
• Thread length capacity: Capable of threading up to 3D in a single setup, expanding opportunities for deep-threading tasks.
• MT7 shank: Compatible with standard MT7 toolholders for secure, repeatable performance.
• Low cutting forces: Short cutting length reduces forces at the cutting edge, supporting smoother operation and longer tool life.

This MTQ thread mill provides a practical, dependable solution for manufacturing tasks that demand precise metric threads in challenging locations. The combination of deep reach, internal coolant, and a rigid design translates to tighter tolerances, reduced cycle times, and better surface finishes—especially when threading into base features or through-holes. It’s ideal for shops prioritizing repeatable performance in aerospace, automotive, or general engineering applications where deep, high-quality threads matter.
