Precision internal-threading tool designed for metric sizes M3, M3.5, and M4 x 0.5, delivering accurate threads in a compact, single-pass operation. This Carmex MT11 single-point carbide thread mill is built for dependable performance in professional machining environments.

• Threading capability: Internal threads are generated in a single pass, enabling fast, reliable production across common standards (ISO M1 x 0.25 to 0-80 UNF).
• Flute design: Multi (3–4) flutes provide stable cutting action and efficient chip evacuation for clean thread profiles.
• Coating and grade: MT11 Ultra-fine sub-micron grade with a triple blue PVD coating for wear resistance and long tool life.
• Profile and versatility: Full-profile internal thread milling geometry optimized for consistent engagement when cutting internal threads.
• Metric sizes supported: Designed for metric threading applications, including M3, M3.5, and M4 x 0.5.
• Material compatibility: Part of Carmex’s solid carbide thread-milling family, intended to perform across a range of materials used in precision components.

These features combine to deliver precise, repeatable internal threads with fewer passes and less tool-changing overhead. The carbide construction paired with MT11 coating helps extend tool life in demanding materials, while the advanced flute geometry supports smooth operation and excellent thread finishes in compact features and small-diameter holes.
