The Carmex MTQ Thread Mills Long Reach Through Coolant, Metric - x 1.5 - MT7 are precision tools engineered for threading medium to large sizes in deep workpieces, including features located at the base of the part. Designed for stability and reliability, they deliver clean, accurate threads even in challenging setups.

• Long reach with overhang capability: specifically built to thread in deep cavities and base features, expanding where standard thread mills can’t reach.
• Through-coolant design: internal coolant bore and through-coolant capability help flush chips, control temperature, and extend tool life during demanding cuts.
• MT7 carbide grade shank: constructed with Carmex MT7 carbide for enhanced rigidity and wear resistance in tough threading applications.
• Internal coolant through the flutes: some MTQ variants feature coolant delivery through the tool’s flutes, contributing to consistent penetration and surface finish in deep holes.
• Thread length up to 3D: capable of cutting relatively long threads to maximize material usage and reduce the number of passes in deep pockets.
• Relieved neck for deep work: relieved neck design facilitates long reach while preserving rigidity at the cutting edge.

With a focus on high cutting stability, these tools minimize vibration, enabling higher cutting speeds and feeds that can shorten cycle times without sacrificing thread quality. The short cutting length further reduces cutting forces, supporting durable performance in demanding environments while still accommodating substantial reaches. These benefits come together to deliver precise threads in challenging geometries, improved chip control, and reliable repeatability across heavy or intricate workpieces.
