Carmex Thread Mills Long Reach Through Coolant are engineered for internal threading of UN profiles (UNC, UNF, UNEF, UNS) in medium to large sizes, with a focus on deep workpieces and base-side features. Built for MT7 spindles, these tools deliver reliable precision and versatility in challenging machining scenarios.

• Through-Coolant Design: internal coolant bore directs cooling to the cutting edges for better temperature control, chip evacuation, and extended tool life.
• Long Reach Geometry: optimized long-protrusion profile to reach deep pockets and base-side threads without sacrificing rigidity.
• UN Thread Compatibility: specifically shaped to mill internal UNC, UNF, UNEF, and UNS threads with consistent pitch and surface finish.
• MT7 Shank Interface: rigid MT7 shank provides secure seating and minimal runout for stable, accurate milling in demanding workpieces.
• Rigid Cutting Action: design minimizes vibrations during threading, enabling higher speeds and feeds for shorter cycles without compromising thread quality.
• Depth-Ready Performance: capable of handling thread milling in deep features and at base positions, expanding the range of manufacturable geometries.

By combining long reach, through-coolant delivery, and a stable MT7 interface, Carmex Long Reach Through-Coolant Thread Mills deliver precise UN-threading in challenging workpieces—from automotive components to aerospace inserts and mold features. Expect cleaner thread profiles, improved surface finish, and more efficient cycles in deep or base-side applications.
