Engineered for professionals who need reliable internal threading in hard-to-reach areas, Carmex Long Reach Through-Coolant Thread Mills (Metric, MT7) are a 3‑piece MTQ set designed to deliver precision on medium to large threads—even deep within the workpiece or at the base.

• Quantity: 3-piece set
• Tool Type: Long‑reach thread mills designed for metric threads with through‑coolant
• Reach: Extended reach to access deep pockets and base‑level threads
• Coolant: Internal through‑coolant bore for efficient cooling and chip evacuation
• Thread Length Capability: Thread lengths up to 3D for versatile applications
• Rigidity: High rigidity and stability to minimize vibration and ensure consistent results
• Cutting Forces: Short cutting length reduces cutting forces for smoother operation
• Interface: MT7 shank compatibility with standard milling machines
• Versatility: Supports overhangs, expanding machining setup options

In practice, the MTQ line focuses on delivering precise, efficient threading with fewer passes. The combination of rigidity and optimized geometry enables higher cutting speeds and feeds, helping reduce cycle times without sacrificing thread quality. The through‑coolant design keeps heat in check and promotes clean, accurate threads, while the long reach unlocks threading in internal features that would otherwise require multiple setups. This 3‑piece MT7 set is well suited for a range of materials and applications where deep, reliable thread milling is essential.
