Carmex MT7 Solid Carbide Internal Thread Mills are built for precise metric threading in tight spaces, delivering reliable internal threads on M10 and M12 x 1.5 fasteners. Designed for shops that value efficiency and cost control, this toolline focuses on dependable performance and long tool life.

• Material: Solid carbide for high rigidity and wear resistance in demanding threading applications.
• Threading capability: Internal thread milling for metric sizes M10 and M12 x 1.5, enabling accurate, repeatable threads.
• Flute count: Multi-flute design (3–5 flutes) to improve cutting action, chip evacuation, and hole finish.
• Interface: MT7 shank interface for strong, stable engagement with standard milling machines and holders.
• Design focus: Geometry and cutting edges optimized for stable thread formation and consistent results across materials.
• Value proposition: Part of Carmex MT line, engineered to provide efficient, cost-effective threading without sacrificing quality.

This internal thread mill is ideal for manufacturing environments that need clean, accurate metric threads in limited-access areas—supporting applications in automotive, machinery, and pneumatic/hydraulic components. By milling threads rather than tapping, you gain better control over thread integrity, reduce the risk of cross-threading, and extend tooling life, all while keeping tooling costs in check. Whether you’re prototyping a new part or sustaining high-volume production, the MT7 internal thread mill helps you achieve precise threads with repeatable results.
