Meet the Carmex Thread Mills Carbide Mini Type — a compact, high-performance threading tool designed for metric M3 x 0.5 threads. Built for precision in internal and external threads, it leverages a robust MT7 shank for rigid, reliable performance at speed.

• Thread size: Metric M3 x 0.5 threading for small-diameter applications
• Tool grade & coating: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10-K20)
• Flute design: Spiral flutes with 3–5 features for smooth cutting and shorter machining times
• Shank: MT7 shank for strong, stable engagement in compact setups
• Coolant through-flutes: Through-coolant enhances deep-hole threading with efficient heat and chip management
• Cutting speed & efficiency: Optimized for medium to high cutting speeds, delivering faster cycles without sacrificing accuracy
• Material versatility: General-purpose performance across materials, including hardened steels up to 45 HRc
• Internal & external threads: One tool can produce both internal and external threads across a wide pitch range
• Durability: Prolonged tool life due to the special triple coating

Benefits: The combination of MT7 carbide and TiAlN coating delivers exceptional wear resistance at elevated speeds, extending tool life and reducing downtime. The short profile reduces cutting forces, enhancing stability and minimizing the risk of broken taps when threading in deep or hard materials. Through-flute coolant and spiral geometry enable efficient chip evacuation and smooth cutting in deep holes, allowing you to thread longer cavities with a single tool. This mini thread mill covers a broad range of pitches and works for both internal and external threads, simplifying setups and boosting productivity. Ideal for workshops and production environments that demand reliable threading on diverse materials, including hardened alloys, at medium to high speeds.
