The Carmex Long Reach Through-Coolant Thread Mill (Metric MT7) is a precision threading tool built for deep, hard-to-reach features. Designed for medium to large diameter threads, it combines rigid construction with efficient cooling to deliver reliable, high-precision results in demanding workpieces.

• Tool family: MTQ long-reach thread milling tools engineered for deep-threading applications
• Through coolant: internal coolant bore enables effective cooling and chip evacuation during cutting
• Long reach with compact cutting: extended shank and short cutting length for enhanced stability and lower cutting forces
• Thread length capability: supports thread lengths up to 3D to tackle deep or base features
• Rigid carbide construction: high stiffness to minimize vibrations and maintain thread accuracy
• Metric MT7 sizing: designed to fit a range of metric thread pitches with reliable performance
• Overhang tolerance: engineered to perform with overhangs, enabling versatile setups in deep workpieces

Engineered for productivity, this MT7 thread mill enables higher cutting speeds and feeds without sacrificing precision. The combination of rigidity and a through-coolant design reduces vibrations and heat buildup, promoting cleaner threads and longer tool life. Its long reach unlocks threading in deep pockets and at the base of parts, often eliminating the need for secondary operations or tool changes. For shops seeking dependable, repeatable threading in challenging geometries, this Carmex MTQ-based tool delivers consistent performance across a range of deep-hole and base-feature applications.
