Meet the Carmex Carbide Mini Thread Mill—precision threading for small-diameter workpieces. Ideal for machinists and engineers who need reliable M2.5 x 0.45 threads in tight spaces, with the versatility to cut both internal and external threads in a single tool.

• Tool Type: Carbide mini thread mill designed for metric M2.5 x 0.45 threads (MT7 grade) with a compact form for confined areas.
• Material & Coating: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10–K20) for wear resistance at higher speeds.
• Flute Design: Spiral flutes with 3–5 cutting edges for smooth cutting action and reduced cutting forces.
• Coolant Through Flutes: Through-flute coolant enhances chip evacuation and performance in deep-hole threading.
• Versatility: Capable of producing both external and internal threads, enabling a wide range of pitches with one tool.
• Performance in Hard Materials: Suitable for hardened materials up to 45 HRc, expanding application across demanding components.
• Depth & Speed Advantage: Short profile and multi-flute geometry deliver shorter machining times at medium to high cutting speeds.
• Durability: Special triple coating and robust geometry extend tool life and reduce the risk of tool breakage in tough materials.

These features translate into practical benefits: you can thread hard, high-strength materials with confidence, complete complex threads in tight pockets, and reduce cycle times without sacrificing thread quality. The combination of through-coolant performance, spiral cutting action, and a compact profile makes this mini thread mill a dependable choice for precision assemblies, medical devices, aerospace components, and electronics housings where exact M2.5 x 0.45 threads are required.
