Carmex MT line Thread Mills deliver precise, cost-efficient internal threading for metric sizes on CNC machines. Designed for engineers and machinists who need reliable M3 and M4 x 0.5 threads without extra tapping steps.

• Solid Carbide Construction: High rigidity and wear resistance for consistent thread quality and long tool life.
• Internal Thread Milling: Create clean, finished threads from within the workpiece, reducing the need for taps.
• Metric Thread Range: Supported sizes include M3 x 0.5 and M4 x 0.5, enabling compact, common threaded features.
• Multi-Flute Geometry: 3–5 flute design enhances chip evacuation and precision during threading.
• MT7 Designation: Standardized MT7 tooling interface for compatibility with common tool holders.
• Cost-Effective Solution: Optimized for efficient threading with reduced cycle times and lower tooling costs.

This thread milling solution helps you streamline production by eliminating separate tapping operations, achieving accurate thread height, and delivering repeatable results across batches. The solid carbide construction withstands demanding materials and cutting conditions, while the 3–5 flute design improves surface finish and minimizes chatter. Ideal for small, metric threads in tight envelopes, it supports quick setups and consistent quality, making it a practical choice for shops focused on precision and value.
