Carmex MTQ Thread Mills Long Reach Through Coolant are designed for robust, precise threading in medium to large sizes, even in deep pockets or features near the base of a part. This 12‑piece MT7 set delivers elite rigidity and a through‑coolant design to keep cutting zones cool and chips flowing for demanding applications.
- Set Size: 12‑piece MT7 through‑coolant thread milling set for convenient stocking and project planning.
- Thread Forms: Compatible with UN, UNC, UNF, UNEF and UNS thread standards for versatile applications.
- Reach and Stability: Long reach with overhang capability maintains rigidity in deep workpieces and base‑level features.
- Internal Coolant: Through‑coolant bore delivers coolant directly to the cutting zone for improved heat management and chip evacuation.
- Cutting Geometry: Short cutting length reduces cutting forces while preserving stability, enabling higher speeds and feeds.
- Thread Length Capacity: Supports thread lengths up to 3D for flexible, one‑tool solution across varying depths.
These features translate into practical benefits: cleaner thread profiles, reduced cycle times from higher cutting speeds, and dependable performance when machining in hard‑to‑reach locations. The MTQ tools excel at deep threading tasks while maintaining control and longevity, making them a reliable choice for precision manufacturing across automotive, aerospace, and general engineering environments.
