The Carmex MT7 internal thread mill is a solid carbide tool engineered for precise metric threading in hard-to-reach holes. Designed for engineers and machinists who need reliable, cost-efficient internal threads in M8 and M10 x 1.25, it’s built to perform in everyday production and job-shop environments.

• Tool Type: Internal thread milling tool for metric threads
• Material: Solid carbide for exceptional wear resistance and long tool life
• Flute Count: 3–5 flutes to enhance cutting stability and chip evacuation
• Thread Sizes: M8 and M10 x 1.25 (MT7 line)
• MT Line Advantage: Optimized threading performance with a cost-effective tooling approach
• Precision & Consistency: Delivers repeatable thread profiles across common metals

With the MT7 internal thread mill, you gain predictable thread quality, reduced cycle times, and lower tooling costs. The multi-flute geometry improves stability during plunge and full-length cuts, helping you achieve clean thread roots and consistent pitch. Its solid carbide construction withstands demanding machining conditions, making it a practical choice for routine production runs, maintenance, and repair work. Ideal for fastening assemblies in automotive brackets, machine housings, and equipment enclosures where accurate internal threads are essential.
