Carmex MT Thread Mills are solid carbide tools designed for precise internal thread milling in metal parts. Built for CNC machinists who need reliable, cost-effective threaded holes, these MT7-thread mills optimize the threading process from roughing to finishing.

• Internal thread milling: Specifically engineered to cut metric threads from the inside of holes with M5 x 0.8 pitch, using the MT7 interface for secure engagement.
• Solid carbide construction: Offers high rigidity, wear resistance, and long tool life for consistent thread quality across materials.
• 3–5 flute design: Optimizes chip evacuation and cutting stability, delivering smooth finishes and improved threading accuracy.
• MT7 shank compatibility: Standard machine interface that ensures strong grip, minimal runout, and reliable performance in compact setups.
• Cost-effective threading solution: Designed to balance performance and value, helping shops reduce tooling costs without sacrificing thread integrity.

This MT line is ideal for creating precise internal threads in aluminum, steel, and other metals, especially in through-holes and blind holes where tapping is impractical. Use cases include threaded inserts, housings, and components requiring robust internal threads with tight tolerances. The combination of multiple flutes, carbide rigidity, and MT7 compatibility translates to repeatable results, efficient material removal, and longer tool life in everyday threading operations.
