Meet the Carmex Carbide Mini Type Thread Mill — a compact, high-performance threading tool designed for internal and external UN threads (UNC, UNF, UNEF, UNS). Sized for 3/8-16 and compatible with MT7 spindles, it delivers speed, versatility, and durability in a single tool.

• Thread types: Universal UN family compatibility (UNC, UNF, UNEF, UNS) for both internal and external threads.
• Thread size: 3/8-16 thread pitch, enabling common fastener standards with a single tool.
• Shank & compatibility: MT7 shank for secure, precise fits in standard high‑speed spindles.
• Material & coating: Carbide MT7 sub-micron grade with a Titanium Aluminium Nitride multi‑layer coating (ISO K10–K20) for long life and reliability.
• Flute design: Spiral flutes with 3–5 teeth for smooth cutting action and efficient chip evacuation.
• Coolant through flutes: Through‑the‑flutes coolant delivers effective cooling and chip removal, especially beneficial for deep-hole threading.
• Cutting performance: Engineered for medium to high cutting speeds with a short profile that reduces cutting forces.
• Material versatility: General purpose tool suitable for a wide range of materials, including hardened steels up to 45 HRC.
• Durability & life: Special triple coating structure enhances tool life and sustains performance over many cycles.

This thread mill makes deep-hole threading more efficient by combining fast cycle times with dependable accuracy. The TiAlN coating and sub-micron carbide substrate resist wear in tough materials, while the through‑coolant design and spiral flutes ensure clean, consistent threads across a variety of pitches. One tool covers a broad range of UN thread options and both internal and external threads, reducing tool changes and simplifying setups. For precision, speed, and durability in UN-thread milling, the Carmex Mini Type Thread Mill is a reliable choice.
