Description
The Carmex MT solid carbide internal thread mill is engineered for precise metric thread milling on CNC machines. It’s built for shops that demand reliable, cost-efficient internal threading for standard metric sizes.
- Thread sizes: Internal milling support for M24 and M28 x 3 metric threads, enabling common applications with a single tool.
- Flute count: 3–5 flutes designed to balance cutting efficiency, chip evacuation, and thread quality.
- Material: Solid carbide construction for exceptional wear resistance and long tool life under demanding speeds and feeds.
- Shank compatibility: MT7 interface for quick tool changes and rigid seating on compatible CNC milling centers.
- Designed for efficiency: Geometry optimized to reduce cycle times while delivering clean, accurate threads.
Achieve repeatable, high-quality metric threads with fewer passes and lower tool cost per thread. The MT line’s multi-flute design improves stability and thread accuracy, while the solid carbide body stands up to tough materials and high-speed conditions. With MT7 compatibility, you gain strong rigidity and easy integration into existing machining setups, making this tool ideal for production runs, repairs, and prototype threading tasks alike.
