Carmex MT7 solid carbide thread mills are engineered for precise G-profile threading (55°) on internal and external surfaces, delivering reliable performance for BSP/BSF applications. Built for efficiency and long tool life, this MT line provides consistent thread quality with fewer tool changes.

- Solid Carbide Construction: high-hardness material for rigidity and wear resistance, supporting stable cuts at threading speeds.
- 3–5 Flutes: multi-flute geometry enhances cutting efficiency, thread accuracy, and chip evacuation for cleaner finishes.
- Internal & External Thread Milling: one tool handles both internal and external threads, reducing setup time and tooling counts.
- G (55°) Thread Profile: specifically shaped for 55-degree G-thread forms used in BSP/BSF standards, delivering consistent thread geometry.
- MT7 Shank Interface: robust MT7 engagement with standard tool holders for stable, repeatable threading performance.
- Cost-Effective Threading Solution: optimized flute count and geometry designed to maximize throughput without sacrificing thread quality.
This thread mill is ideal for production environments and precision assemblies where BSP and BSF connections are critical. Use it to machine piping fittings, valve components, and other parts requiring reliable G-thread threads with repeatable results. The MT7 design ensures a rigid cut, minimizes chatter, and supports efficient material removal—helping you achieve accurate threads every cycle.
