The Carmex MT7 Solid Carbide Internal Thread Mills are built for precise metric threading inside holes, delivering reliable performance for a range of metalworking applications. This line is designed for shops that prioritize accuracy, efficiency, and cost-effectiveness in thread production.

• Solid carbide construction: Rugged, wear-resistant body that holds its edge through repeated threading passes, even in tough materials.
• Internal thread milling capability: Precisely creates metric threads in holes, including M6 and M8 x 1, without the need for tapping.
• Flute count: 3–5 flutes optimized for clean cutting, smooth chip evacuation, and stable engagement.
• MT7 designation: Part of the MT7 family, aligned with Carmex's lineup of efficient thread milling tools.
• Size and compatibility: Designed to accommodate standard metric thread profiles M6 and M8 x 1 in through-holes and blind holes as required.
• Efficiency and cost-effectiveness: The multi-flute geometry and carbide construction reduce cycle times and tooling costs compared with traditional tapping, while delivering consistent thread quality.

With these tools, you gain the ability to produce accurate internal threads with fewer setups and less tooling changeover. The MT7 internal thread mill supports high-speed milling, improves surface finish on threaded holes, and reduces the risk of tool breakage due to its robust carbide composition. This makes it an excellent choice for fastener pockets, housings, enclosures, and other components requiring reliable metric threads in metal.
