Meet the Carmex Thread Mills Carbide Mini Type MT7 – a compact, high‑performance thread milling tool engineered for machinists who require precise G and BSP thread forms in deep holes and across a broad range of materials. Designed for internal and external threads with a single cutter, it delivers fast, reliable threading at medium to high cutting speeds.

• Thread form and sizes: 55° G threads (BSF/BSP) with G1/2 and G7/8×14 sizing, optimized for versatile applications in hard metals and precision assemblies.
• Carbide grade and coating: MT7 sub‑micron carbide with a Titanium Aluminium Nitride multi‑layer coating (ISO K10–K20) for outstanding wear resistance and extended tool life.
• Through‑coolant design: Coolant through the flutes enhances chip evacuation and cooling in deep‑hole threading, reducing heat buildup and extending tool life.
• Flute geometry: Spiral flutes (3–5) deliver smooth cutting action, efficient chip removal, and reduced cutting forces thanks to the short profile.
• Depth and versatility: Enables machining in deep holes and can produce a wide range of threads and pitches using the same tool, including both external and internal threads.
• Material capability: General‑purpose performance suitable for all materials, including hardened workpieces up to 45 HRc, with reliable results at higher speeds.
• Durability and efficiency: Multi‑layer coating and short tool profile provide longer life and shorter machining times, helping you finish jobs faster with fewer tool changes.
• Practical reliability: Designed to minimize breakage and maintain consistent thread quality across challenging productions and repetitive runs.

This MT7 carbide mini thread mill is a thoughtful choice for engineers and production shops aiming for precise, repeatable threads in hard materials and tight spaces. Its combination of through‑coolant capability, versatile threading options, and durable coating translates to fewer tool changes, cleaner thread finishes, and improved uptime on high‑speed threading tasks.
