The Carmex Carbide Mini Thread Mill is a compact, high-precision tool designed for fast, accurate threading in metalworking. Ideal for machinists who need small metric threads with a single, versatile tool, it excels in deep holes and tight spaces while delivering reliable performance at higher speeds.

• Thread size: Metric M3.5 x 0.6 threads, suitable for small-diameter connectors, fasteners, and components.
• Material and coating: MT7 sub-micron carbide substrate with a TiAlN multi-layer coating for extended wear resistance.
• Through-coolant: Internal coolant channels deliver through-the-flutes cooling and chip evacuation, ideal for deep-hole threading.
• Flute geometry: Spiral flutes provide smooth cutting action; 3–5 flutes shorten the machining cycle and reduce cutting forces.
• Compatibility: Works for both internal and external threads using a single tool; accommodates a wide range of pitches.
• Performance: Optimized for medium to high cutting speeds with short machining times, including hardened materials up to 45 HRc.
• Durability: Short tool profile minimizes deflection and prevents broken taps; triple-coated design extends tool life.
• Deep-hole threading: Specifically engineered to enable threading in deep holes with efficient coolant delivery through the flutes.

The result is precise, repeatable threads with excellent surface finish, even in tough alloys. By combining internal and external threading capabilities in one tool, you reduce downtimes and tool changes while maintaining tight tolerances. The MT7 carbide core and TiAlN coating resist wear at high speeds, delivering consistent performance across jobs and increasing overall productivity in high-speed threading tasks.
