The Carmex MTZ Thread Mills are carbide, through‑coolant tools engineered for precision threading in through‑holes. Designed for MT7 toolholders and machines without external coolant, they deliver coolant directly to the cutting edge for a smoother, cooler, more reliable cut.

• Material: Carbide for exceptional rigidity, wear resistance, and long tool life
• Through-Coolant Flutes: Integrated coolant channels deliver coolant directly to the cutting edge for efficient cooling and chip evacuation
• Threading Focus: Optimized for through‑hole threading with direct chip removal, improving surface finish and tolerance control
• Thread Form: G (55°) thread geometry with BSF/BSP compatibility for versatile applications
• Shank: MT7 toolholder compatibility for broad CNC compatibility and quick changes
• Size: x 11 diameter/length specification as indicated by the product title

This tooling excels in situations where through‑hole threading is essential, such as in fasteners, components with internal threads, or assemblies requiring reliable internal engagement. The through‑coolant design minimizes heat buildup at the cutting edge, reducing built‑up edge, extending tool life, and delivering consistent thread quality. Compared to standard dry‑drilling or non‑coolant thread mills, the MTZ range maintains performance in materials that generate higher cutting temperatures, while remaining compatible with machines that don’t have an external coolant supply. Ideal for precision shops and maintenance environments seeking dependable, maintenance‑friendly thread milling without added coolant infrastructure.
